DTC Fault Trigger Conditions






Visual Inspection and Diagnostic Pre-checks

- Inspect BJB (Battery Junction Box) fuse 13 (30A).

Pinpoint Test

1. CHECK THE PCM (Powertrain Control Module) STARTER RELAY CIRCUITS FOR A SHORT TO VOLTAGE

1. Ignition OFF.

2. Disconnect: ACM (Audio Control Module) C240A.

3. Disconnect: PCM (Powertrain Control Module) C175B.

4. Disconnect: Starter Relay.

5. Ignition ON.

6. Measure:





Is any voltage present?






2. CHECK THE PCM (Powertrain Control Module) STARTER RELAY CIRCUITS FOR A SHORT TO GROUND

1. Ignition OFF.

2. Measure:





Are the resistances greater than 10,000 ohms?






3. CHECK THE PCM (Powertrain Control Module) STARTER RELAY CIRCUITS FOR AN OPEN

1. Measure:





Are the resistances less than 3 ohms?






4. CHECK FOR CORRECT PCM (Powertrain Control Module) OPERATION

1. Disconnect and inspect all PCM (Powertrain Control Module) connectors.

2. Repair:

- corrosion (install new connectors or terminals - clean module pins)
- damaged or bent pins - install new terminals/pins
- pushed-out pins - install new pins as necessary

3. Connect the PCM (Powertrain Control Module) connectors. Make sure they seat and latch correctly.

4. Operate the system and determine if the concern is still present.

Is the concern still present?
