PINPOINT TEST S : The Hazard Lamp Function Is Inoperative Or Always On
- S1 CHECK THE RECORDED DTCs FROM THE BCM SELF-TEST
- Ignition ON.
- Using a scan tool, perform the BCM on-demand self-test.
Is DTC B1D35:11 present?
Yes GO to S2. No GO to S4. - S2 ISOLATE THE FCIM AS THE CAUSE OF DTC B1D35:11
- Ignition OFF.
- Disconnect: FCIM.
- Ignition ON.
- Using a scan tool, perform BCM on-demand self-test.
Is DTC B1D35:11 still present?
Yes GO to S3. No GO to S6. - S3 CHECK THE HAZARD LAMP REQUEST INPUT CIRCUIT FOR A SHORT TO GROUND
- Ignition OFF.
- Disconnect: BCM C2280B.
- Measure:
Positive Lead Measurement / Action Negative Lead C2402-4 Ground
Is the resistance greater than 10, 000 ohms?
Yes GO to S7. No REPAIR the circuit. - S4 CHECK FOR A VOLTAGE SIGNAL TO THE FCIM
- Disconnect: FCIM.
- Ignition OFF.
- Measure:
Positive Lead Measurement / Action Negative Lead C2402-4 Ground
Is the voltage greater than 11 volts?
Yes GO to S6. No GO to S5. - S5 CHECK THE HAZARD FLASHER LAMP REQUEST INPUT CIRCUIT FOR AN OPEN
- Disconnect BCM C2280B.
Is the resistance less than 3 ohms?
Yes GO to S7. No REPAIR the circuit. - S6 CHECK FOR CORRECT FCIM OPERATION
- Disconnect and inspect all FCIM 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 FCIM connectors. Make sure they seat and latch correctly.
Is the concern still present?
Yes CHECK OASIS for any applicable TSBs. If a TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB instructions. If no TSBs address this concern, INSTALL a new FCIM. REFER to Information and Entertainment Systems Premium . 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. - S7 CHECK FOR CORRECT BCM OPERATION
