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

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

Test E1-E3:

Normal Operation
The parking aid module communicates with the diagnostic tool through the international standard organization (ISO) 9141 communications network circuit 70 (LB/WH). Check circuit 70 (LB/WH) between the parking aid module C2023 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 circuit 70 (LB/WH), damage to the DLC C251, damage to the parking aid module C2023, or a problem in the in-line connectors.

Possible Causes
- circuit 70 (LB/WH) open
- in-line connector
- DLC C251
- parking aid module C2023
- parking aid module
