Test I: The Parking Aid Module Does Not Respond To The Diagnostic Tool
PINPOINT TEST I: THE PARKING AID MODULE DOES NOT RESPOND TO THE DIAGNOSTIC TOOLI1-I2:
I2-I3:
Normal Operation
The parking aid module communicates with the diagnostic tool through the medium speed controller area network (CAN), circuits VDB06 (GY/OG) and VDB07 (VT/OG). Check the medium speed CAN circuits between the parking aid module C4014 and the data link connector (DLC) C251. The total resistance values must not be more than 5 ohms. If the resistance is more than 5 ohms there is an open in one of the high speed CAN circuits, damage to the DLC C251, damage to the parking aid module C4014, or a problem in an in-line connector.
Possible Causes
- medium speed CAN data plus circuit VDB06 (GY/OG) open
- medium speed CAN data minus circuit VDB07 (VT/OG) open
- parking aid module C4014
- parking aid module
