Pinpoint Test I : IPMB (Image Processing Module B) DTC (Diagnostic Trouble Code) U3006:16
- I1 RECHECK FOR DTC (DIAGNOSTIC TROUBLE CODE) U3006:16
- Ignition ON.
- Using a diagnostic scan tool, clear the IPMB Diagnostic Trouble Codes (DTCs).
- Operate the rear video camera system to determine if the concern is still present.
- Using a diagnostic scan tool, check the IPMB Continuous Memory Diagnostic Trouble Codes (CMDTCs).
Is DTC U3006:16 still present?
Yes GO to I2 No The system is operating normally at this time. The DTC may have been set due to a previous low battery voltage condition or an intermittent fault. - I2 CHECK FOR CHARGING SYSTEM DIAGNOSTIC TROUBLE CODES (DTCS) IN THE PCM (POWERTRAIN CONTROL MODULE)
- Using a diagnostic scan tool, check the PCM Continuous Memory Diagnostic Trouble Codes (CMDTCs).
Are any voltage-related Diagnostic Trouble Codes (DTCs) present in the PCM?
Yes Refer to the appropriate Engine article for the procedure. No GO to I3 - I3 CHECK THE BATTERY CONDITION AND STATE OF CHARGE
- Check the battery condition and verify that the battery is fully charged. REFER to: Battery .
Is the battery OK and fully charged?
Yes GO to I4 No CHARGE the battery or INSTALL a new battery as necessary. REFER to: Battery Charging . - I4 CHECK THE IPMB (IMAGE PROCESSING MODULE B) VOLTAGE SUPPLY
- Ignition OFF.
- Disconnect IPMB C4402 .
- Ignition ON.
- Measure and record the battery voltage at the battery.
Is the voltage measured at the IPMB within 0.2 volt of the recorded battery voltage?
Yes GO to I5 No REPAIR the circuit. - I5 CHECK THE IPMB (IMAGE PROCESSING MODULE B) GROUND CIRCUIT
Is the voltage greater than 11 volts?
Yes GO to I6 No REPAIR the circuit. - I6 CHECK FOR CORRECT IPMB (IMAGE PROCESSING MODULE B) OPERATION
- Ignition OFF.
- Disconnect and inspect the IPMB connector.
- 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 connector. Make sure it seats and latches correctly.
- Operate the system and determine if the concern is still present.
Is the concern still present?
Yes CHECK 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 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.
