Ignition Control
B2102-IGNITION RUN/START INPUT CIRCUIT HIGH
For a complete wiring diagram consult Diagrams/Electrical.
- 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.
Diagnostic Test
1. CHECK FOR ACTIVE DTC
NOTE: Check to make sure the battery and charging system are operating properly. Battery and/or 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 WIN DTC(s).
Perform 5 ignition cycles, leaving the ignition switch on for a minimum of 30 seconds per cycle.
Using the scan tool, read WIN 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. Body Verification Test
2. (F20) IGNITION SWITCH OUTPUT (RUN-START) SHORTED TO BATTERY VOLTAGE
Turn the ignition off.
Disconnect the TIPM C3 harness connector.
Measure the voltage of the (F20) Ignition Switch Output (Run-Start) circuit in the TIPM C3 harness connector.
Is voltage present?
Yes
- Go To 3
No
- Replace the TIPM.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test
3. CHECK WIN FOR AN INTERNAL SHORT TO VOLTAGE
Disconnect the WIN harness connector.
Reconnect the TIPM C3 harness connector.
Turn the ignition on.
With the scan tool, read DTCs
Does the scan tool display this DTC as active?
Yes
- Repair the (F20) Ignition Switch Output (Run-Start) circuit for an short to battery voltage.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test
No
- Replace the WIN.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test
