Image Processing Module (IPMA)

CAUTION: Diagnosis by substitution from a donor vehicle is NOT acceptable. Substitution of control modules does not guarantee confirmation of a fault, and may also cause additional faults in the vehicle being tested and/or the donor vehicle.

NOTE:

Guided Diagnostics must be followed and the repair advised by the process completed. Failure to do so may result in the rejection of any warranty claim made.
If a control module or a component is at fault and the vehicle remains under manufacturer warranty, refer to the Warranty Policy and Procedures article, or determine if any prior approval program is in operation, prior to the installation of a new module/component.

The service information below lists all Diagnostic Trouble Code(s) that could be set in the Image Processing Module (IPMA). For additional diagnosis and testing information, refer to the relevant Diagnosis and Testing article in the service information. For additional information, Refer to: HEADLAMPS
