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

E1-E2:

Normal Operation
The parking aid module communicates with the diagnostic tool through the ISO 9141 communication network circuit 70 (LB/WH). If circuit 70 (LB/WH) becomes open or shorted to ground, communication to that module is not possible. Check circuit 70 (LB/WH) between the parking aid module C4014 and the data link connector (DLC) C251. 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 C4014, or a problem in an in-line connector.

Possible Causes
- ISO 9141 communication network circuit 70 (LB/WH) open
- DLC C251
- C4014
- parking aid module
