CAMERA, Forward Facing, [XAK] / Video Control Processor For DTC B2286-00 - Calibration not learned/Lost calibration set by the Central Vision Processing Module (CVPM), DO NOT try to run a service calibration routine before replacing the part. Otherwise, the historical environmental data will be erased. Please contact one of the following: Sam Tkac at (248) 821-7819 Bing Guo at (248) 500-7355 If no response in 15 minutes, proceed with repair. For additional help, please provide/perform the following procedure via email to bg589@chrysler.com and sam.tkac@fcagroup.com. 1. Obtain a vehicle scan report and configuration report, this will capture all CVPM DTCs and any critical environmental data. 2. Take a picture of the radio head unit display when in surround view mode to show what the Top+ Rear view looks like when the fault is active. 3. Perform diagnosis ECU reset, or ignition off have radio go to sleep mode. Verify if the DTC is still active. 4. Inspect the CVPM harness and related in-line harness connections to ensure the connectors are assembled correctly, with no connector damage, pinched wires, terminals pushed out, bent pins, or water intrusion. 5. If the wiring harness and connections appear to be good and B2286-00 is still active, replace the CVPM and return to QEC for root cause analysis. DO NOT try to run a service calibration routine before replacing the part. Otherwise, the historical environmental data will be erased.
