Test D: The Parking Aid Module Does Not Respond to the Diagnostic Tool

PINPOINT TEST D: THE PARKING AID MODULE DOES NOT RESPOND TO THE DIAGNOSTIC TOOL

D1:

D2-D3:

Normal Operation
The parking aid module communicates with the diagnostic tool through the international standards organization (ISO) 9141 communications network, circuit 70 (LB/WH). Check circuit 70 (LB/WH) 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 the ISO 9141 circuit, damage to the DLC C251, damage to the parking aid module C4014, or a problem in an in-line connector.

Possible Causes
- ISO 9141 communications network, circuit 70 (LB/WH) open
- parking aid module C4014
- parking aid module
