DTC Fault Trigger Conditions
DTC Description Fault Trigger Condition IPMB B14A5:11 Multi-Camera View Switch: Circuit Short To Ground A continuous and on-demand DTC that sets in the IPMB when the camera selection switch is stuck closed or the circuit is shorted to ground. Possible Sources
- Wiring, terminals or connectors concern
- Camera selection switch concern
- IPMB concern
Visual Inspection and Pre-checks
- Inspect the camera selection switch to verify that the switch is not damaged or stuck in the pressed position.
- L1 CHECK FOR DIAGNOSTIC TROUBLE CODES (DTCS) FROM THE IPMB (IMAGE PROCESSING MODULE B) SELF-TEST
- Ignition ON.
- Using the diagnostic scan tool, perform the IPMB self-test.
Are any Diagnostic Trouble Codes (DTCs) retrieved?
Yes For DTC B14A5:11, GO to L2 For all other Diagnostic Trouble Codes (DTCs), Refer to the DTC Chart: IPMB . No GO to L4 - L2 CHECK THE CAMERA SELECTION SWITCH
- Ignition OFF.
- Disconnect Camera Selection Switch C2480.
- Ignition ON.
- Using a diagnostic scan tool, clear the IPMB Diagnostic Trouble Codes (DTCs) and repeat the self-test.
Is DTC B14A5:11 still present?
Yes GO to L3 No INSTALL a new camera selection switch. - L3 CHECK THE CAMERA SELECTION SWITCH CIRCUIT FOR A SHORT TO GROUND
- Ignition OFF.
- Disconnect IPMB C2512A.
- Measure:
Positive Lead Measurement / Action Negative Lead C2480-2 Ground
Is the resistance greater than 10, 000 ohms?
Yes GO to L6 No REPAIR the circuit. - L4 CHECK FOR GROUND AT THE CAMERA SELECTION SWITCH
- Ignition OFF.
- Disconnect Camera Selection Switch C2480.
- Measure:
Positive Lead Measurement / Action Negative Lead C2480-3 Ground
Is the resistance less than 3 ohms?
Yes GO to L5 No REPAIR the circuit. - L5 CHECK THE CAMERA SELECTION SWITCH CIRCUIT FOR AN OPEN
- Ignition OFF.
- Disconnect IPMB C2512A.
Is the resistance less than 3 ohms?
Yes INSTALL a new camera selection switch. If the concern is still present after replacing the switch, GO to L6 No REPAIR the circuit. - L6 CHECK FOR CORRECT IPMB (IMAGE PROCESSING MODULE B) OPERATION
- Ignition OFF.
- Disconnect and inspect the IPMB 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 IPMB 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 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 IPMB. Refer to: Image Processing Module B (IPMB) . No The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. ADDRESS the root cause of any connector or pin issues.
