DTC Fault Trigger Conditions
DTC Description Fault Trigger Condition BCM B10F1:14 Key In Switch: Circuit Short To Ground Or Open A continuous and on-demand DTC that sets in the BCM if an open is detected on the key-in-ignition switch input with the ignition ON. Possible Sources
- Wiring, terminals or connectors
- Interior lighting concern
- Key-in-ignition switch (part of the ignition switch)
- BCM
- GWM
- IPC
- BP1 CHECK THE SEATBELT WARNING CHIME OPERATION
- Ignition OFF.
- Ignition ON.
- Monitor the seatbelt warning chime when the ignition switch is transitioned from OFF to RUN for 6 seconds.
Does the seatbelt warning chime operate for approximately 6 seconds?
Yes GO to BP2 No GO to Pinpoint Test BV - BP2 CHECK THE INTERIOR LAMPS OPERATION
- Open and close the driver door.
- Observe the interior lamps.
Do the interior lamps operate correctly from the driver door?
Yes GO to BP3 No Refer to Interior Lighting . - BP3 CHECK THE GWM (GATEWAY MODULE A) DIAGNOSTIC TROUBLE CODES (DTCS)
- Using a diagnostic scan tool, check the GWM Continuous Memory Diagnostic Trouble Codes (DTCs).
Are any Diagnostic Trouble Codes (DTCs) recorded?
Yes Refer to Communications Network . No GO to BP4 - BP4 PERFORM THE BCM (BODY CONTROL MODULE) SELF-TEST
- Using a diagnostic scan tool, perform the BCM self-test.
Is DTC B10F1:14 present?
Yes GO to BP5 No GO to BP8 - BP5 CHECK THE KEY-IN-IGNITION INPUT CIRCUIT FOR VOLTAGE
- Ignition OFF.
- Insert the key into the ignition cylinder.
- Disconnect BCM C2280D.
- Measure:
Positive Lead Measurement / Action Negative Lead Refer to C2280D-22 Ground
Is the voltage greater than 11 volts?
Yes GO to BP8 No GO to BP6 - BP6 CHECK THE KEY-IN-IGNITION INPUT CIRCUIT FOR SHORT TO GROUND
- Remove the key from the ignition cylinder.
- Measure:
Positive Lead Measurement / Action Negative Lead Refer to C2280D-22 Ground
Is the resistance greater than 10, 000 ohms?
Yes GO to BP7 No REPAIR the circuit. - BP7 CHECK THE KEY-IN-IGNITION INPUT CIRCUIT FOR OPEN
- Disconnect Ignition Switch C250.
Is the resistance less than 3 ohms?
Yes REPAIR the circuit. No DIAGNOSE the ignition switch. Refer to Steering Wheel and Column Electrical Components . - BP8 CHECK FOR CORRECT BCM (BODY CONTROL MODULE) OPERATION
- Ignition OFF.
- Disconnect and inspect the BCM connectors.
- Repair:
- corrosion (install new connector or terminals - clean module pins)
- damaged or bent pins - install new terminals/pins
- pushed-out pins - install new pins as necessary
- Reconnect the BCM connectors. Make sure they seat and latch correctly.
- Operate the system and verify the concern is still present
Is the concern still present?
Yes CHECK On-Line Automotive Service Information System (OASIS) for any applicable service articles: TSB, GSB, SSM or FSA. If a service article exists for this concern, DISCONTINUE this test and FOLLOW the service article instructions. If no service articles address this concern, INSTALL a new BCM. No The system is operating correctly at this time. The concern may have been caused by module connections. ADDRESS the root cause of any connector or pin issues.
