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).
