Wheels and Tires
Overview
This section will provide basic information to assist in the diagnosis of tire-related faults.
Tire pressure monitoring systems (TPMS) have been introduced on 2006 my vehicles and this section will also provide
information to assist in the diagnosis of the system.
For information on the operation of the systems:

TPMS inspection and verification
1 . Verify the customer complaint.
NOTE:
Record any messages displayed by the system.
2 . Visually inspect for obvious mechanical or electrical faults.

3 . If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the
next step.
4 . Use the approved diagnostic system or a scan tool to retrieve any diagnostic trouble codes (DTCs) before moving onto
the DTC index.
Make sure that all DTCs are cleared following rectification.
DTC Index
NOTE:
Generic scan tools may not read the codes listed, or may read only 5-digit codes. Match the 5 digits from the scan
tool to the first 5 digits of the 7-digit code listed to identify the fault (the last 2 digits give extra information read by the
manufacturer-approved diagnostic system).
