For a complete wiring diagram Consult Diagrams/Electrical.

- When Monitored:
With the ignition switch on.

- Set Condition:
The PTCM has detected the system voltage above a calibrated value.





Diagnostic Test

1. DETERMINING IF DTC IS CURRENT
NOTE: Diagnose any related Powertrain DTC(s) before continuing.

With a scan tool, read and record DTC(s).
With the scan tool, clear DTC(s).
Perform 5 ignition cycles, leaving the ignition switch on for a minimum of 90 seconds per cycle.
Using the scan tool, read DTC(s).
Does the DTC reset?

Yes

- Go to 3

No

- Go to 2

2. INTERMITTENT CONDITION
NOTE: Check for any of the follow conditions:
- Poor wire to terminal connection
- Corroded terminals
- Backed out or loose terminals
- Broken wire internal to the insulation
- Dirty (partial) module ground


With the ignition on, wiggle the related wires.
Using a scan tool, read DTC(s).
Does the DTC reset?

Yes

- Repair the wiring as necessary.
- Perform SKREEM VERIFICATION TEST. Vehicle Theft Security Verification Tests

No

DTC is not active at this time. Test complete.

3. FUSED IGNITION SWITCH OUTPUT (RUN-START) CIRCUIT SHORTED TO BATTERY VOLTAGE
NOTE: A dirty (partial) ground can cause abnormal conditions within a system. Ensure the module has a good ground before continuing.

Turn the ignition off.
Disconnect the SKREEM harness connector.
Using a 12 volt test light connected to ground, probe the Fused Ignition Switch Output (Run-Start) circuit in the SKREEM harness connector.
Does the test light illuminate brightly?

Yes

- Repair the Fused Ignition Switch Output (Run-Start) circuit for a short to voltage.
- Perform SKREEM VERIFICATION TEST. Vehicle Theft Security Verification Tests

No

- Replace and reprogram the SKREEM.
- Perform SKREEM VERIFICATION TEST. Vehicle Theft Security Verification Tests
