Tire Monitor System - False Warning Triggered

NO: JTB00224

ISSUE: 1

DATE: 25 MAY 2011

SECTION: 204

Tire Pressure Monitoring System False Trigger

AFFECTED VEHICLE RANGE:
XJ (X351) VIN: V00001-V21616
Model Year: 2010 - 2011

CONDITION SUMMARY:

Situation:

The Tire Pressure Monitoring System (TPMS) warning light may be illuminated with the message Tire Pressure Monitoring Fault displayed in the message center. The Body Control Module (BCM) will also have logged code C1D18-00 in isolation. The charging circuit emits a 125MHz electromagnetic pulse which is picked up by the TPMS wheel sensor, causing the system to fail to localize all of the sensors.

NOTE:
Ensure DTC C1D18-00 is the only code stored; other system faults may also cause this DTC to be stored in combination with other DTCs.

NOTE:
Replace all four (vehicle set [five low tire pressure sensors if the vehicle's spare tire / wheel is fitted with a TPMS sensor]) low tire pressure sensors for this concern.

Action:

In the event of a customer concern of the above, refer to the Repair Procedure outlined below to replace the complete set (four or five) low tire pressure sensors.
