B2101-IGNITION RUN/START INPUT LOW

For a complete wiring diagram Refer to Section 8W.

When Monitored:
With the ignition switch on.
Set Condition:
The SKREEM has detected the ignition switch input voltage below a calibrated value.

FUSED IGNITION SWITCH OUTPUT (RUN-START) CIRCUIT OPEN

Diagnostic Test

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

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.

DTC is not active at this time. Test complete.

3. 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

Repair the Fused Ignition Switch Output (Run-Start) circuit for an open.
Perform SKREEM VERIFICATION TEST.

4. SKREEM

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.
Start the engine.
Using the scan tool, view battery voltage under Data Display in the Engine category.
Compare the voltage on the scan tool to the voltage reading on the voltmeter.

Is the voltage on the scan tool equal to the voltmeter reading +/- .5 volt?

Yes

Replace and program the SKREEM in accordance with the Service Information.
Perform SKREEM VERIFICATION TEST.

Repair the Fused Ignition Switch Output (Run-Start) circuit for high resistance.
Perform SKREEM VERIFICATION TEST.
