Possible Causes

Scheme 3

1. 1) CHECK FOR ACTIVE DTC Turn the ignition on. With a scan tool, read, record and erase TIPM DTCs. Turn the ignition off for 30 seconds, then back on. Using the scan tool, read TIPM DTCs. Does the scan tool display this DTC as active? Yes Go To 2) . No 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»(ref-306151-S09725333202008120900000) .
2. 2) (F20) IGNITION SWITCH OUTPUT (RUN-START) CIRCUIT OPEN NOTE: Check the related fuse (TIPM 46) to the (F20) Ignition Switch Output (Run-Start) circuit. If blown, use the wiring diagrams as a guide to make necessary repairs. Turn the ignition off. Disconnect the TIPM C7 harness connector. Turn the ignition on. Using a 12-volt test light connected to ground, probe the (F20) Ignition Switch output (Run-Start) circuit in the TIPM C7 harness connector. Does the test light illuminate brightly? Yes Replace the TIPM in accordance with the service information. Perform «BODY VERIFICATION TEST - VER 1»(ref-306151-S09725333202008120900000) . No Repair the (F20) Ignition switch output circuit for an open. Perform «BODY VERIFICATION TEST - VER 1»(ref-306151-S09725333202008120900000) .

1. When Monitored: With the ignition switch on.

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

Scheme 4

1. 1) CHECK FOR ACTIVE DTC 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) . No 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»(ref-306151-S09725333202008120900000) .
2. 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/SKIM VERIFICATION TEST»(ref-306165-S38861671682008120900000) . No Replace and program the WCM/WIN (SKREEM) in accordance with the service information. Perform «SKREEM/SKIM VERIFICATION TEST»(ref-306165-S38861671682008120900000) .
