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?

Yes


- 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.
