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.
