Pinpoint Test C : DTC (Diagnostic Trouble Code) B12D8:11, DTC (Diagnostic Trouble Code) B12D8:13

WARNING: This page is about a different car, the 2018 Ford F-550 Super Duty, 2018 Ford F-450 Super Duty, 2018 Ford F-350 Super Duty, and 2018 Ford F-250 Super Duty. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Before replacing the IPMA camera heated windshield element or the IPMA for an IPMA camera heated windshield element concern, verify the integrity of the wiring, connectors and terminals on the IPMA camera heated windshield element jumper harness.

C1 CHECK FOR RECORDED DIAGNOSTIC TROUBLE CODES (DTCS) FROM THE IPMA (IMAGE PROCESSING MODULE A) SELF-TEST

Ignition ON.

Using a diagnostic scan tool, perform the IPMA self-test.

Is DTC B12D8:11 or DTC B12D8:13 present?

Yes	* For DTC B12D8:11, GO to C2. * For DTC B12D8:13, GO to C5

No	The system is operating correctly at this time. INSPECT the connectors, wiring and the IPMA camera heated windshield element for damage or poor connections.

C2 CHECK FOR DTC (DIAGNOSTIC TROUBLE CODE) B12D8:11 WITH THE IPMA (IMAGE PROCESSING MODULE A) CAMERA HEATED WINDSHIELD ELEMENT DISCONNECTED

Ignition OFF.

Disconnect IPMA Camera Heated Windshield Element C9048A and C9048B .

Ignition ON.

Using a diagnostic scan tool, clear the IPMA Diagnostic Trouble Codes (DTCs).

Perform the IPMA self-test.

Is DTC B12D8:11 present?

Yes

GO to C3

No	INSTALL a new IPMA camera heated windshield element. Refer to: Image Processing Module A (IPMA) Camera Heated Windshield Element . After the repair, CLEAR the Diagnostic Trouble Codes (DTCs), CYCLE the ignition, and RUN the IPMA on-demand self-test to re-enable the circuit.

C3 CHECK THE IPMA (IMAGE PROCESSING MODULE A) CAMERA HEATED WINDSHIELD ELEMENT OUTPUT CIRCUIT FOR A SHORT TO GROUND

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

Ignition OFF.

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 (integral to the interior rear view mirror). 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.
