Hi, what does P0605 mean?


this answer courtesy of obd-codes.com code p0605 What does that mean? This trouble code basically means that the PCM/ECM (powertrain/engine control module) has detected an internal control module fault in the ROM (read only memory) in the PCM. The PCM is basically the vehicle's "electronic brain" that controls functions such as fuel injection, ignition, etc. When self-checks fail in the ROM, this DTC is set. This code is a generic powertrain code. It is considered generic because it applies to all makes and models of vehicles (1996-newer), although specific repair steps may be slightly different depending on the model. A cursory search on the 'net shows this DTC to be more commonly found in Ford and Nissan vehicles. Symptoms Symptoms of a P0605 DTC will include MIL (malfunction indicator lamp) illumination, although there may be other symptoms including but not limited to various warning lights on dash, stalling, and no start conditions. Potential Causes There is an internal fault in the PCM / ECM Using an aftermarket performance programmer may trigger this code Possible Solutions In some cases, "flashing" the PCM with an updated software can fix this DTC. You will need acess to make & model specific information such as Technical Service Bulletins (TSBs). If there are no PCM flash updates, the next step would be to check some wiring. Inspect and check for proper voltage and ground to the PCM and throughout the associated circuits. If there are problems with them, repair and retest. If the wiring checks out OK, the next step is to replace the PCM, which is the most likely repair for this code. This is generally not a "do-it-yourself" task, although in some cases it may be. We strongly recommend you have a qualified repair shop / technician do the work, one that has the capability to reprogram the new PCM. Installing the new PCM may involve using special tools to program the vehicle's VIN (vehicle identification number) and/or anti-theft information (PATS, etc.). As an alternative to replacing the PCM, some specialized shops may actually be able to repair the PCM. That may involve removing the PCM, shipping it off to them for repair, and re-installing it. That's not always an option for daily drivers. N

What does the code 1686 mean for a jeep grand cherokee


you have dash lamps acting funny?
diesel engine? or gas, and what displacement? 4.0 , 4.7
P1686


did the immo lamp glow.
did you scan the PCM and see if 1685 (wrong key code)
1686, rigth out of fsm

Trouble Code: P1686 4.7L
No SKIM Bus Messages Received
Number of Trips to Set Code: 1
PCM details.
Trouble Code Conditions:
Engine started; and the PCM did not detect any MIC (I/P Cluster) messages over the Data Bus circuit for 20 seconds.
Possible Causes:
  • Data Bus circuit from MIC to the PCM is damaged or it is open
  • Instrument Cluster is damaged or has failed
  • PCM unable to communicate with the Instrument Cluster
  • PCM has failed
this means, the PCM can not talk to the I/P cluster puter.
comm fail.
even wilder guess is PCM talks to KEY via cluster so if cluster dead
so be key.
bad fuses ?

the FSm dont cover defeating any alrarms or IMMO less crooks read it. so...... google it.

P0443 p0689 p1516 p1682 p2101 p2176 i have had the map sensor replaced the ignition switch, fuel pump , maf sensor throttle actuator control and the car still stalls and pulls all these codes the mechanic...


Code p0689 may be the answer as it refers to the ECM power relay control---circuit open. code 0443 refers to the EVAP purge valve---circuit malfunction. I have not got the codes for the rest as they are specific to GMC. But I suspect that the faults will all relate to the ECM

I need info on a icm or code p0601


Causes

A code P0601 in most cases means the PCM has gone bad. This is possibly due to a short-circuit inside the PCM. Or, if you disconnect the wires/connector from the PCM while the battery is still connected, that may also cause this code.

Possible Solutions

With a P0601 OBD-II trouble code, the most common fix is to replace and reprogram the PCM. In a few cases the dealer may be able to reflash the PCM and get it working. But more than likely the PCM will need to be replaced and reprogrammed (we recommend you take it to a dealership for this). The good news is it *may* be covered under your emmissions warranty. So even if you're out of bumper-to-bumper warranty or powertrain warranty, check your warranty guide or dealer to see if this is covered.

Other people have reported that they cleared the code only for it to return again and again. Keep in mind that most shops can replace the PCM but not all can program it.

How can fix code P0703 on mazda 6i v6 2005


The conditions that set this code are as follows:

The PCM monitors changes in input voltage on Brake Switch No. 1. If the PCM does not sense voltage changes at PCM terminal 82 when alternately accelerated and decelerated 8 times, the PCM determines that brake switch No. 1 has a malfunction

Possible Causes are:
  • Brake Switch malfunction
  • connector or terminal malfunction
  • Short to power circuit between Brake Switch terminal D and PCM terminal 82
  • Open circuit between Brake Switch terminal D and PCM terminal 82
  • Malfunctioning PCM

I have 3 ipc codes what does ipc stand for 98 cadillac eldorado


IPC stands for Instrument panel control, here is a typical code repair flow chart, this is for example only and has nothing to do with your car..
P083 = 24x signal high.

P107 = Instrument panel control )IPC) to computer (PCM) data problem.

P137 = Loss of Automatic braking system (ABS) to Traction control system (TCS).

What you need to do is CLEAR all these codes from the computer and see which ones return.

Perform this test.

1. Ignition key ON. Engine OFF.

2. Simultaneously push and hold the OFF and WARMER (^) buttons on your climate control panel for 3 seconds and release them.

3. Diagnostic codes such as above will appear with the word HISTORY or CURRENT for each code.

4. The codes will stop when you see PCM?

5. Push and release the HI(^) button and you will see PCM DATA?

6. Push and release the LO(v) button and you will see PCM DATA?

7. Continue to push and release the LO (v) button until you see PCM CLEAR CODES?

8. Push and release the HI(^) button until you see PCM CODES CLEAR.

9. Turn OFF the ignition and wait 3 minutes and try and start the car. If the car starts and the light comes back ON, Turn OFF the car and repeat steps 1 thru 3 and let me know what codes you get and if they are HISTORY or CURRENT.

10. When you see PCM?, Turn OFF ignition key.

11. Let me know what codes you get and if they are HISTORY or CURRENT.



---------- FOLLOW-UP ----------

QUESTION: this is what happen when it did what you told me what to do.
P047 History,P107 History,No IPC Code, P83 History,P137 History, A047 Current, No Sir Codes, T072 History,No Russ, PCM?
ANSWER: You did not follow the directives correctly . If you had, You would NOT have any HISTORY CODES.

Try it again and follow these directives EXACTLY:

1. Ignition key ON. Engine OFF.

2. Simultaneously push and hold the OFF and WARMER (^) buttons on your climate control panel for 3 seconds and release them.

3. Diagnostic codes such as above will appear with the word HISTORY or CURRENT for each code.

4. The codes will stop when you see PCM?

5. Push and release the HI(^) button and you will see PCM DATA?

6. Push and release the LO(v) button and you will see PCM DATA?

7. Continue to push and release the LO (v) button until you see PCM CLEAR CODES?

8. Push and release the HI(^) button until you see PCM CODES CLEAR. WAIT 3 seconds and then proceed to 9.

9. Turn OFF the ignition and wait 3 minutes and try and start the car. If the car starts and the light comes back ON, Turn OFF the car and repeat steps 1 thru 3 and let me know what codes you get and if they are HISTORY or CURRENT.

10. When you see PCM?, Turn OFF ignition key.
