Diagnostic Test

1. VERIFY THAT THE DTC IS ACTIVE

CAUTION: Diagnose and repair all Powertrain DTCs before continuing.

Turn the ignition on.

With the scan tool, record and erase the SKREEM DTCs.

Perform 5 ignition cycles, leaving the ignition switch on for a minimum of 90 seconds per cycle.

Using the scan tool, read the SKREEM DTCs.

Does the DTC reset?

Yes

- Go To 2

No

- Go To 3

2. CHECK THE (F202) FUSED IGNITION SWITCH OUTPUT (RUN-START) CIRCUIT FOR A SHORT TO BATTERY VOLTAGE





NOTE: A dirty (partial) ground can cause abnormal conditions within a system. Ensure that 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 (F202) Fused Ignition Switch Output (Run-Start) circuit in the SKREEM harness connector.

Does the test light illuminate brightly?

Yes

- Repair the (F202) Fused Ignition Switch Output (Run-Start) circuit for a short to voltage.
- Perform SKREEM VERIFICATION TEST. Vehicle Theft Security Verification Tests

No

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

3. CHECK THE WIRE HARNESS FOR CAUSE OF INTERMITTENT CONDITION

NOTE: Check for all of the following 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.

With the scan tool, read DTC(s).

Does the DTC reset?

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

No

The DTC is not active at this time. Test complete.
