FUSED IGNITION SWITCH OUTPUT (RUN-START) CIRCUIT OPEN
NOTE: Check the related fuses to the Fused Ignition Switch Output
(Run-Start) circuit. If the fuse is found to be open repair the circuit
for a shorted condition.
Turn the ignition off.
Disconnect the SKREEM harness connector.
Turn the ignition on.
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
>> Go to 4
No
>> Repair the Fused Ignition Switch Output (Run-Start) circuit
for an open.
Perform SKREEM VERIFICATION TEST.
4.
FUSED (B+) CIRCUIT OPEN
Turn the ignition off.
Using a 12 volt test light connected to ground, probe the Fused (B+)
circuit in the SKREEM harness connector.
Does the test light illuminate brightly?
Yes
>> Go to 5
No
>> Repair the Fused (B+) circuit for an open.
Perform SKREEM VERIFICATION TEST.
5.
SKREEM
NOTE: Repeat the below procedure for both the Fused Ignition Switch Output (Run-Start) circuit and the
Fused (B+) circuit.
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.
Reconnect the SKREEM connector.
Back probe the Fused Ignition Switch Output (Run-Start) circuit and then the Fused (B+) circuit.
Start the engine.
Using the scan tool, view battery voltage under Data Display in the Engine category.

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.
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.
No
>> Replace and reprogram the SKREEM in accordance with the Service Information.
Perform SKREEM VERIFICATION TEST.
