A4 CHECK THE VDM (VEHICLE DYNAMICS CONTROL MODULE) VOLTAGE (VDM_SUPPLY_V) PID (PARAMETER IDENTIFICATION)
Ignition ON. Measure and record the voltage at the battery. Using a diagnostic scan tool, monitor the VDM_Supply_V PID.
Is the PID) display within 0.2 volt of the recorded battery voltage?
Yes | GO to A7 |
|---|---|
No | GO to A5 |
A5 CHECK THE VDM (VEHICLE DYNAMICS CONTROL MODULE) VOLTAGE SUPPLY
Ignition OFF. Disconnect VDM C4585A. Ignition ON. Measure:
Click to display connectors
Positive Lead | Measurement / Action | Negative Lead |
|---|---|---|
C4585A-16 | Ground | |
C4585A-32 | Ground |
Is the voltage within 1 volt of the recorded battery voltage?
Yes | GO to A6 |
|---|---|
No | VERIFY BJB fuse 66 (5A) and BCM fuse 25 (30A) are OK. If OK, REPAIR the affected circuit for high resistance or an open. If not OK, REFER to the Wiring Diagrams manual to identify the cause of the circuit short. |
A6 CHECK THE VDM (VEHICLE DYNAMICS CONTROL MODULE) GROUND CIRCUIT FOR AN OPEN
Measure:
Click to display connectors
Positive Lead | Measurement / Action | Negative Lead |
|---|---|---|
C4585A-47 | Ground |
Is the resistance less than 3 ohms?
Yes | GO to A8 |
|---|---|
No | REPAIR the circuit. |
