I will start by pinout check current + to ECM and - ground there is many .
A Quad driver work like a big fuse d?pends some are resettable and other not reset(ECM defect) if it is so then you have to check all solenoid not short to ground before replacing ECM it will burn without checking the solenoid
hope it help

It's a 1995 Saturn sl the clutch on ac compressor kicks on with direct power the engine fan also changed relays still get the code 26 quad drive modal need some help


This info is from 1998 Saturn Sl , my service info doesn't go to 95 . It's the same except for code numbers , My info is P0xxx #'s . The quad driver is part of the ECM - engine computer !
Here is a description from Saturn service info .
A quad driver module (QDM) is an electronic switch which completes a ground circuit when switching ON. The QDM independently controls 4 separate outputs. A load is connected between battery voltage and the QDM allowing the QDM driver to control the output. Each QDM has fault detection logic which compares QDM driver input and output voltages. The logic expects to measure less than 3 volts when the QDM driver is ON and greater than 7 volts when OFF. The QDM has only one fault line that will detect a fault on any of the 4 outputs. The scan tool can be used to cycle the outputs ON or OFF. The scan tool can also perform an automated test which can isolate the faulty circuit.
The quad drive it self may be bad , GM had a problem with these !
Did you check fuse's ?
Conditions for Setting the DTC
DTC P01650 and/or P1651 will set if:
?€¢
There is an open, short to ground or short to voltage on any of the QDM output circuits


?€¢
MIL (SERVICE ENGINE SOON) telltale circuit


?€¢
Upshift lamp circuit


?€¢
Cooling fan relay circuit


?€¢
A/C relay circuit


?€¢
Fault detected for 5 seconds for DTC P1651. Fault detected for 20 seconds for DTC P1650.

Important: The QDM circuit is continuously checked when the engine is running.

Tip

Understanding of your vehicle's trouble codes


First off this information is intended for your knowledge only. This is not a substitute for any specialized training that may be needed for your specific problem. That being said this list presents a general assortment of domestic generic obd2 codes (vehicles 96/present). Certain makes have their own specialized codes which may differ from these. Here is the basic breakdown of the obd code: you'll have a letter first and four numbers, the letters are p/powertrain, b/body, c/chassis, and u/network (most trouble codes listed on this site are p codes). The first number will be either a 0 or 1. 0 is a generic listing, 1 means it is a manufactuers specific code (remember I mentioned there are other variations like p2**** etc. they are not mentioned here). The second number represents the type of problem you'll encounter 1 being fuel & air metering, 2 is for injector circuit problems, 3 is misfires or faulty ignition system components 4 is emissions related 5 controls vehicles speed and idle 6 is for computer and auxiliary outputs 7 & 8 refer to faults in your transmission. The last 2 numbers in the code represent the problem. I will not list all of them, but I'll list a broad enough spectrum to give you an educated point of reference to check. p0100 mass or volume air flow circuit malfunction p0101 mass or volume air flow performance problem, p0102 mass or volume air flow cicuit low input p0103 circuit high input p0104 circuit intermittent p0105-9 manifold air pressure circuit problem p0111-14 intake air control circuit p0115-19 engine coolant temp. circuit p0120-24 throttle positioning sensor circuit p0125-26 insufficient coolant temp. p0126-167 O2 sensor problems p0170-75 fuel trim (too rich or lean) p0176-79 fuel composition sensor circuit p0180-89 fuel temp. sensor circuit p0190-94 fuel rail pressure p0195-99 engine oil temp sensor. Now into fuel injection injector circuit section: p0200-212 injector circuit malfunction p0213-14 cold start injector p0215 engine shutoff solenoid (Now that we know these are all p0 series codes I'll save myself some typing) 216 injection timing control 217 engine overheating condition 218 transmission overheating 219 engine reached speed limit (limiter) 220-29 throttle/pedal position sensor 230-33 fuel pump 234 engine overboost (turbo) 235-42 turbo boost sensors 243-250 wastegate solenoids 251-260 injection pump fuel metering controls 261-96 cylinder injection circuit faults. Now the p03 series, ignition system and misfires 300 mulitple misfire 301-12 represent those cylinders misfiring (1 for cyl. 1 and 5 for cyl. 5 etc.) 320-23 engine speed input 325-34 knock sensors 335-39 crankshaft positioning sensor 340-44 camshaft positioning sensor 350-62 these represent ignition coils (same as 301-312 did with cylinders above) 370-79 timing reference signal 380-81 glow plug heater circuit (diesel) 382 bad egr (exhaust gas recirculation) 385-89 crankshaft position sensor b. Now the p04 series for emissions related problems 400-08 exhaust gas recirculation flow (low or high) or circuit malfunction 410-19 secondary air injection system 420-34 catalyst system 440-55 evaporative emission control systems 460-64 fuel level sensor 465-69 purge flow sensor 470-79 exhaust pressure sensor/controls 480-85 electric cooling fans. Now onto the p05 series for idle/speed control 500-03 vehicle speed sensor 505-07 idle control system 510 closed throttle positioning switch 520-23 engine oil pressure sensor 530-34 a/c refrigerant pressure sensor 550-54 power steering pressure sensor 560-64 system voltage problems 565-599 are cruise control related. Now the p06 series for your computer output 600 communication link problem 601 internal control module memory 602 bad module programming 603 module kam error (keep alive memory) 604 module ram error (random access memory) 605 module rom error (read only memory) 606 pcm fault(powertrain control module) 608-9 control module vss output malfunction (in electronic circuits vss is the positive supply and vdd in the negative/ground source s=source and d=drain on mos transistor devices) 650 mil lamp circuit (malfunction indicator lamp or simply your check engine light) 654 engine rpm (revoultions per minute) output 656 fuel level output. Now for sections p07&800s transmissions (This section will be brief, I hate working on transmissions and do not specialize in them. A simple piece of debris/dirt when reassembling a rebuilt transmission in the valve body is enough to cause it to wear out rather quickly. Without the proper training and test equipment this is the most difficult part of the vehicle to diagnose or fix). p0700-02 transmission control system 703 torque converter/brake 705-709 trans. range sensor 710-14 trans. fluid temp. sensor 715-718 input/turbine speed 720-23 output speed sensor 725-29 engine speed input 730 incorrect gear ratio 731-35 are incorrect gear ratios for those individual gears (same as p0301-12) 736 incorrect reverse gear 740-44 torque converte clutch 745-49 pressure control solenoid 750-74 shift solenoid malfunctions 780 shift malfunction 781 1st-2nd shift 782 2nd-3rd 783 3rd-4th 784 4th-5th 785-89 shift/timing solenoid 790 normal/performance switch circuit 801 reverse inhibit control 803 1st-4th upshift (skip shift) solenoid control. I hope these definitions have given you a better understanding of where your problem/s may be located. To determine the exact problem like a low circuit voltage input etc, etc. your specific code/s will be needed to give you that more detailed info. If you provide me with that info along with the specifics of your vehicle: year, make, model, engine size and a brief description of the problem you've had I'd be glad to help you in anyway I can. Thanks again for using fixya your source for the answers you need for everyday problems. Posted by Edwin37323

Can you tell me the location of code reader 1991 capri ?


1991 is pre-OBD2. code readers will not work.
sorry.
however, all is not lost. Many cars have an alternate way of reading codes from the computer.
Toyota has a block under the hood and you short couple wires together and count engine light flashes
Chrysler you can turn the ignition key on and off a few times and count engine light flashes
in your case for GMs from 1982 to 1995
1: find the 12 pin connector under the dash and short the upper two rightmost terminals.
with the ignition "ON" and engine not running. The system will enter the diagnostic mode. In this mode, the computer will display a Code 12, three consecutive times, by flashing the "CHECK ENGINE", "SERVICE ENGINE SOON" or "MALFUNCTION INDICATOR LAMP" or light. A Code 12 consists of one flash, a short pause, then two flashes in rapid succession.
2:. After Code 12 is displayed, any stored trouble codes will be displayed by flashing the "CHECK ENGINE", "SERVICE ENGINE SOON" or "MALFUNCTION INDICATOR LAMP" light. All codes are displayed 3 times each then a code 12 will repeat. In the diagnostic mode, the computer will also energize all computer controlled relays and solenoids.

What does diagnostic code PO0706 and PO700 mean?


OBD II Fault Code
  • OBD II P0706
Fault Code Definition
  • Transmission Range Sensor Circuit Range/Performance
The purpose of the automatic transmission is to match the engine's optimum power and torque characteristics to the driver's desired rate of acceleration and speed by auto-selecting different gear ratios or 'speeds' to power the wheels. The Transmission Range Sensor (also referred to as the PRNDL input and/or neutral safety switch) tells the transmission control module (TCM) and the powertrain control module (PCM) that the transmission is in park, reverse, neutral, drive, low, 2nd, 3rd etc. It is attached directly to the manual valve of transmission, so when the shift lever is moved say from park to drive, the Transmission Range Sensor communicates this critical information to the above mentioned vehicle computer systems.

P0700
Many vehicles have a control module for the automatic transmission called a transmission control module (TCM). The engine control module (ECM) communicates with the TCM to monitor the automatic transmission for faults. If the TCM detects a fault in the automatic transmission and sets a transmission related fault code, the ECM is informed of this also and sets a P0700 in the ECM memory.

I need to know what the code 18 and 41 means for 93 Buick Park Avenue Ultra with a 3.8 litre supercharged eng


When fixing codes start with first code first / it dos not always mean that the sensor is the fault ,it could be in the harness / the plug or the ground. and reference signal should be tested , but in this case you most likely could get away with replacing the cam sensor, that would be the Lest expensive and easiest to start with,to git to it you will have to remove the alternator hope this is help full, the other code suggest that it could be the crank sensor , that and the plug for it does fail quite often but first things first feel free to ask if you should have any further questions , Thank you ,

How do i get the trouble codes off a 1989 mazda mpv?


http://img178.imageshack.us/img178/3331/obdikx3.jpg

The above link is to a diagram of your ALDL connector, all you need is a paper clip, straighten out the paper clip and insert one end into the diagnostic test pin and one in the system ground pin (terminals A & B).

Then put the key in the ignition and turn it to the on position but DO NOT start the engine. You will then see the check engine light flash. It will initially start by flashing once, then a pause and then flash twice and it will repeat this three times. That flash sequence indicates 12, which just means the system is operating. Its the flash sequences after that that will give you the code if any are stored.

For instance if it flashes twice, then pauses, then flashes four times, thats code 24. So any flash sequence you get after the initial 12 (flash once, pause, flash twice) you need write those down. Below is a list of diagnostic codes to tell you what the codes mean.

Code 12
1 flash, pause, 2 flashes
Diagnostic: This Code will flash whenever the diagnostic terminal is grounded with the ignition switch turned on and the engine is not running.

Code 13
1 flash, pause 3 flashes
Oxygen sensor voltage stays between 0.35 and 0.55 volts for 30 seconds when the TPS signal was above 0.55 volts. The engine had been running for at least 40 seconds with an engine temperature above 110° F.

Code 14
1 flash, pause, 4 flashes
Coolant temperature sensor signal indicates a temperature of over 284° F for 4 seconds after the engine had been running for at least 10 secondsCoolant Sensor Circuit (high temperature) If the engine is experiencing overheating problems, have those fixed before continuing. Check all wiring and connectors associated with the coolant temperature sensor. Replace the Coolant temperature sensor.

Code 15
1 flash, pause, 5 flashes
Coolant Sensor Circuit (low temperature) Coolant temperature sensor signal indicates a temperature colder than -36° F for at least 4 seconds after the engine had been running for 2 seconds. See above, then check wiring connections at the ECM

Code 16
1 flash, pause, 6 flashes
Charging system voltage was either below 9 volts or above 17 volts for 10 seconds. System High Voltage If the voltage is above 17.1 volts for more than 2 seconds, the Service Engine Soon light will illuminate. Have the charging system checked.

Code 17
1 flash, pause, 7 flashes
PCM did not detect any spark reference pulses within 240 fuel control reference pulses (80 crank revolutions) while engine was running below 1200 RPM. Spark Reference Circuit.

Code 21
2 flashes, pause, 1 flash
Throttle Position Sensor, TPS voltage was above 0.8 volts for 5 seconds when engine was running and air flow was less than 15 gm/sec, or the TPS voltage was over 4.8 volts at any time.

Code 22
2 flashes, pause, 2 flashes
Throttle Position Sensor check TPS adjustment. Replace the TPS sensor. TPS voltage was under 0.2 volts for 4 seconds when the ignition was on. Check for a sticking, or mis-adjusted throttle position sensor.

Code 23
2 flashes, pause, 3 flashes
Inlet air temperature sensor signal showed an air temperature of -29° F for 4 seconds. Manifold Air Temperature. Check the MAT sensor, wiring, and connectors for a possible open circuit. replace the MAT sensor.

Code 24
2 flashes, pause, 4 flashes
Vehicle speed sensor signal showed less than 3 MPH for 2 seconds when engine speed was greater than 3000 RPM and transmission has not been in park or neutral for more than 4 seconds. Or vehicle speed goes from above 18 MPH to 0 in less than 2 seconds without applying brake. This code can only appear when the vehicle is in motion, if it appears when the car is not in motion, ignore it. Check ECM connections, any other problems should be diagnosed by a qualified mechanic.

Santa Fe Code p1529


I am sorry the above codes is general error code , the error your getting is car specific hence the codes where not there in the list:

P0715
Input speed sensor system

If no output pulse is detected from the input shaft speed (PG-A) sensor for 1 second or more while driving in 3rd or 4th gear at a speed of 30 km/h or more, it is judged to be an open or short circuit . In the input shaft speed sensor and diagnosis code P0715 is output. If diagnosis code P0715 is output four times, the transmission is locked into 3rd gear (D range) or 2nd gear as a fail-safe measure

P1529
TCM MIL request signal, this code sets in the computer engine control module when there is a transmission fault code
