Test L: The Parking Aid Module Does Not Respond To The Diagnostic Tool

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

L1-L3:

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 the ISO 9141 circuit 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 network, damage to the DLC C251, or damage to the parking aid module C4014.

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