B2102-IGNITION RUN/START INPUT CIRCUIT HIGH

For a complete wiring diagram Refer to Section 8W.

When Monitored:
With the ignition switch on.
Set Condition:
The WCM/WIN (SKREEM) Module has detected the ignition switch input voltage above a calibrated value.

(F20) IGNITION SWITCH OUTPUT (RUN-START) CIRCUIT SHORTED TO BATTERY VOLTAGE

Diagnostic Test

NOTE: Check to make sure the battery and charging system are operating properly. Battery and charging system problems may cause these DTC's to set.

NOTE: Diagnose any related Powertrain DTC(s) before continuing.

Turn the ignition on.
With a scan tool, read, record and erase WCM/WIN (SKREEM) DTC(s).
Perform 5 ignition cycles, leaving the ignition switch on for a minimum of 90 seconds per cycle.
Using the scan tool, read WCM/WIN (SKREEM) DTC(s).

Does the scan tool display this DTC as active?

Yes

Go To 2

The condition that caused this code to set is not present at this time. Check for an intermittent condition by inspecting the related wiring harness for chafed, pierced, pinched, and partially broken wires. Also inspect the related connectors for broken, bent, pushed out, spread, corroded, or contaminated terminals.
Perform BODY VERIFICATION TEST - VER 1. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE)

2. (F20) IGNITION SWITCH OUTPUT (RUN-START) SHORTED TO BATTERY VOLTAGE

Turn the ignition off.
Disconnect the WCM/WIN (SKREEM) harness connector.
Using a 12-volt test light connected to ground, probe the (F20) Ignition Switch Output (Run-Start) circuit in the WCM/WIN (SKREEM) harness connector.

Does the test light illuminate brightly?

Yes

Repair the (F20) Ignition Switch Output (Run-Start) circuit for a short to battery voltage.
Perform SKREEM VERIFICATION TEST.

Replace and program the WCM/WIN (SKREEM) in accordance with the service information.
Perform SKREEM VERIFICATION TEST.
