Parking Distance System Intermittent Operation

AFFECTED VEHICLE RANGE:
LR3 (LA)

VIN:
5A000259 to 5A346777

CONDITION SUMMARY:

INTERMITTENT REAR PARKING AID OPERATION

Situation:
A customer may report a concern that the Parking Distance Control (PDC) system does not operate every time when reversing.

The PDC system was configured to receive both "vehicle stationary" and "electronic parking brake" (EPB) signals together to activate the system. In production the system has been changed so that the "vehicle stationary" signal is ignored and EPB "drive away" signal activates the system.

Action:
If a customer complains of the intermittent condition, refer to the Repair Procedure detailed in this bulletin to replace the parking aid control module with the latest configuration.

PARTS:

*NOTE:
This bulletin has been re-issued to update the parts information with a superseded part number. The previous control module YWC500313 is replaced by YWC500550.*
