Looking for wire for heater gage temperature


Depending on the year there isn't any . All done by computer on serial data bus communication network. The coolant temp. is supplied to the engine computer By a ETC - engine coolant temp sensor . All the modules on the vehicle ( ABS , air bags , BCM , instrument cluster , RKE module etc... ) Share info on this data bus network . If the gauge isn't working probably bad ,If a communication network problem the gauge will default to fixed temp degree . This is for a 1999 Buick , out of factory service repair manual . But all vehicles are pretty much the same .
Engine Coolant Temperature Gauge
The Powertrain Control Module (PCM) via the class II serial data line to the instrument cluster, broadcasts the coolant temperature. The instrument cluster compares the temperature data using a 16 point look-up table in order to determine the needle deflection. A smooth filter is used in order to secure a continuous response. The instrument cluster drives the temperature gauge to C (cold) under the following conditions:
• The temperature data is lost.
• The PCM is in a state of health fault.

Torque converter clutch solenoid


You can use the car & ruin the transaxle & then
spend $4,000 to replace it & still have the same
can area network issues

There is no need to replace wiring,nothing happens to it

Why not properly diagnose the CAN Protocal issues & find
a solution

Your saying the dealer is out of knowledge or skills?

Abs on vr commodore light stays on solutions


Error logs are a great thing. They will help you find intermittent problems and start you off in a general direction of where a problem could be. There is a great level of detail on the justcommodores site on checking error codes logged by the engine management system, but this does not detail anything about the abs system. The abs warning light is not as common as the check engine warning light. Reading through the posts, I haven't found any detail on checking error codes logged by the abs system.

So here it is. For those of you familiar with checking the engine error codes, this procedure is so simple its not funny.

Basically, to check the engine error log, you bridge the 5th (ground) and 6th pins in the ODB connector under the steering wheel.

To check the ABS error log, using the same trusty calibrated paper clip, you simply bridge pins 5 and 12 of the connector.

To find pins 5 and 12, start at the top left hand corner. That is pin one. Going to the right, you count pin 2,3,4 etc. Once you get to the end, jump back to the start of the bottom left level of pins and keep counting. Pin 5 is about halfway along the top row, pin 12 is a little left of the middle in the bottom row.

Reading the error codes is the same procedure (counting the flashes), except now, the ABS light flashes (as opposed to the engine light when checking the engine codes).

The ABS log also uses code 12 firstly, with any errors logged shown after that. If no errors are logged, the 12 will flash again.

Error codes for the ABS error log (VR/VS) are as follows:

12 Diagnostic system operational
21 Right hand front wheel speed sensor fault
23 Right hand front wheel speed sensor continuity fault
25 Left hand front wheel speed sensor fault
27 Left hand front wheel speed sensor continuity fault
28 Wheel speed sensor frequency error
31 Right hand rear wheel speed sensor fault
33 Right hand rear wheel speed sensor continuity fault
35 Left hand rear wheel speed sensor fault
37 Left hand rear wheel speed sensor continuity fault
41 Right hand front inlet solenoid valve circuit fault
42 Right hand front outlet solenoid valve circuit fault
45 Left hand front inlet solenoid valve circuit fault
46 Left hand front outlet solenoid valve circuit fault
55 Rear inlet solenoid valve circuit fault
56 Rear outlet solenoid valve circuit fault
61 Pump motor relay circuit fault
63 Valve relay circuit fault
71 ABS control module internal fault

The above guide has been verified on a VR/VS. Checking the error log on all models prior to VR/VS is the same for the engine log, and I would assume that the same can be said for the ABS log, would be happy if someone could verify this for me.

My SLK 280 2006 is showing the Check engine light ON and the gear not changing neither by automatic drive or tiptronic drive. checking by computer fault log it shows first the O2 sensor malfunctioning. I...


replace the speed sensor as it controls the shifting of the transmission. When replacing any units the fault s will continue to reappear unless you have the CPU reset by a fault code reader.

What does check dcl mean


DCL is Data Communincations Link... the communication connection between the computers in the instrument cluster and the rest of the car. its usually caused (99% of the time) by a bad connection.

The Data Communications Link (DCL) is a wiring system that allows the sharing of information between the Electronic Engine Control System (EEC-IV) , the Electronic Instrument Cluster (EIC) and external equipment.

The EEC-IV system transmits the following information through the DCL to the EIC:
Engine RPM.
Engine coolant temperature.
EEC-IV malfunction indication.
Fuel used.

The DCL system transmits Malfunction Indicator Lamp (MIL) information to the EIC. The EIC uses MIL information to generate a CHECK ENGINE warning in the event of an engine sensor failure.

The EIC will display the message "CHECK DCL" on its Message Center Display if it is not receiving data from the EEC-IV. This warning is turned off whenever data communication is restored.

The EEC-IV monitors the Data Communication Link for faults. If a fault occurs in data communication a continuous Memory Code is set in the EEC-IV. The DCL Codes (529 for EEC-IV and 533 for EIC) can occur separately or together. These codes are not immediately cleared when data communication is restored.

The existance of a DCL code does NOT mean that a module has failed. also I would check for an oil leak or coolant leak that would be the cause of the smoking under the car.

I got a code from auto zone that is i believe UO 101 AND UO105 OR UA101 AND UA105 WHAT do these codes stand for


These codes are communications code errors:

The UO101 is a transmission communication error: poor communication to your transmission ECM / computer

The UO105 is a fuel injection communication error: Poor communication to your fuel injector ECM/ computer.

Code error U1300 scanner


This code pertains to communication from one computer to the next,they all are on a communication circuit (class II) & you have a short to ground somewhere.If a scan tool is able to communicate with the computer(and it is since you got a failure code) this code is intermitten.Get a good volt meter or scan tool & start at the ALDL (where the scanner plugs in).Inspect & check wiring as you keep an eye on the scanner or meter.

DTC Parameters
DTC U1300 will set if the EBTCM, PCM, or SDM detected the Class II circuit in the low state for too long. (Class II circuit shorted to ground) when:
• Condition exists for longer than 4 seconds for EBTCM, 2 seconds for PCM and SDM.
• Ignition is On.

DTC U1300 diagnostic runs continuously with ignition On.

DTC U1300 is a type C DTC.
Diagnostic Aids
If the scan tool can communicate with the EBTCM, PCM or SDM, then the Class II link is not currently shorted to ground.

Inspect the wiring harness for signs of chafing or broken insulation.

Important: The controller name won't be displayed until the scan tool initially received the correct controller ID over the link upon ignition On.

Important: The BCM CANNOT set U1300.

To locate an intermittent problem, use the scan tool to monitor any of the controllers on the Class II link located under DIAGNOSTIC CIRCUIT CHECK - - - CLASS II MESSAGE MONITOR with ignition On, engine Off. INACTIVE will be displayed on all controllers if the link is shorted to ground.


Hope this helps (remember to rate this answer).
