Lead 1 Measurement / Action Lead 2 C9048A-1 C9048B-1
- Ignition ON.
- Using a diagnostic scan tool, clear the IPMA Diagnostic Trouble Codes (DTCs).
- Perform the IPMA self-test.
Is DTC B12D8:11 or DTC B120C:11 present?
Yes REMOVE the fused jumper wire. Except Raptor, INSTALL a new windshield. REFER to: Fixed Glass . For Raptor, INSTALL a new camera windshield defrost heater. No REMOVE the fused jumper wire. GO to C6 - C6 CHECK THE IPMA (IMAGE PROCESSING MODULE A) CAMERA HEATED WINDSHIELD ELEMENT CIRCUITS FOR AN OPEN
- Ignition OFF.
- Disconnect: IPMA C9224 (Except Raptor).
- Disconnect: Interior Rear View Mirror C9012 (Raptor).
- Measure:
Except Raptor
Positive Lead Measurement / Action Negative Lead C9224-8 C919-4 C9224-1 C919-10 Raptor
Positive Lead Measurement / Action Negative Lead C9012-11 C9048A-1 C9012-14 C9048B-1
Are the resistances less than 3 ohms?
Yes GO to C7 No REPAIR the affected circuit. - C7 CHECK FOR CORRECT IPMA (IMAGE PROCESSING MODULE A) OPERATION
- Disconnect and inspect all IPMA connectors and related in-line 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 IPMA connectors and related in-line connectors. Make sure they seat and latch correctly.
- Operate the system to 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 the TSB instructions. If no Technical Service Bulletins (TSBs) address this concern, INSTALL a new IPMA (except Raptor) or INSTALL a new Interior Rear View Mirror (Raptor). Except Raptor REFER to: Image Processing Module A (IPMA) . For Raptor REFER to: Interior Rear View Mirror . 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.
