DTC Fault Trigger Conditions
DTC Description Fault Trigger Condition BCM B10F1:13 Key In Switch: Circuit Open An on-demand DTC that sets if the BCM detects an open on the key-in-ignition switch input circuit or if the BCM detects ignition START, RUN/START or RUN/ACC inputs without the key-in-ignition input. Possible Sources
- Wiring, terminals or connectors
- Exterior lighting concern
- Interior lighting concern
- PRNDL concern
- Key-in-ignition warning switch (part of the ignition switch)
- BCM
- IPC
- AT1 CHECK THE IPC (INSTRUMENT PANEL CLUSTER) FOR MESSAGE CENTER MESSAGES
- Ignition ON.
- Check the IPC and message center for illuminated warning indicator or message center displays.
Does the IPC have any message center messages displayed?
Yes REFER to Symptom Chart: IPC or Symptom Chart: Message Center . No GO to AT2 - AT2 CHECK THE EXTERIOR LIGHTING OPERATION
- Place the headlamp switch in the OFF position.
- Close all doors.
- Wait one minute.
- Observe the exterior lights.
Are the headlamps and parking lamps off?
Yes GO to AT3 No REFER to: Headlamps . REFER to: Parking, Rear and License Plate Lamps . - AT3 CHECK THE INTERIOR LIGHTING OPERATION
- Open and close the driver door.
- Observe the interior lights.
Do the interior lights operate correctly from the driver door?
Yes GO to AT4 No REFER to: Interior Lighting . - AT4 CHECK THE PRNDL OPERATION
- Shift the transmission through the ranges and observe the PRNDL display operation.
Does the PRNDL indicate the correct gear and display P when in PARK (P)?
Yes GO to AT5 No REFER to: Interior Lighting . - AT5 RETRIEVE THE RECORDED DIAGNOSTIC TROUBLE CODES (DTCS) FROM THE BCM (BODY CONTROL MODULE) SELF-TEST
- Using a diagnostic scan tool, perform the BCM self-test.
Are any Diagnostic Trouble Codes (DTCs) present?
Yes For DTC B10F1:13, GO to AT6 For all other Diagnostic Trouble Codes (DTCs), REFER to: Body Control Module (BCM) . No GO to AT8 - AT6 CHECK THE KEY-IN-IGNITION INPUT CIRCUIT FOR VOLTAGE AT THE BCM (BODY CONTROL MODULE)
- Ignition OFF.
- Remove the key from the ignition cylinder.
- Disconnect BCM C2280D.
- Measure:
Positive Lead Measurement / Action Negative Lead C2280D-62 Ground
Is any voltage present?
Yes GO to AT7 No GO to AT8 - AT7 CHECK KEY-IN-IGNITION INPUT CIRCUIT FOR A SHORT TO VOLTAGE AT THE BCM (BODY CONTROL MODULE) WITH THE IGNITION SWITCH DISCONNECTED
- Disconnect Ignition Switch C250.
- Measure:
Positive Lead Measurement / Action Negative Lead C2280D-62 Ground
Is any voltage present?
Yes REPAIR the circuit. No INSTALL a new ignition switch. REFER to: Ignition Switch . - AT8 CHECK FOR CORRECT BCM (BODY CONTROL MODULE) OPERATION
- Ignition OFF.
- Disconnect and inspect all 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 determine if the concern is still present
Is the concern still present?
Yes CHECK OASIS for any applicable Technical Service Bulletins (TSBs). If a TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB instructions. If no Technical Service Bulletins (TSBs) address this concern, INSTALL a new BCM. REFER to: Body Control Module (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.
