DIAGNOSIS-ENGINE CONTROL SYSTEM 62-529
FAULT CODE TABLE

The following table will help you find the cause of failure. You tests every component in this
order and replaces them as needed.
△ PROMPT:
If aDTCis displayed during theDTC check in the inspection mode, the corresponding
circuitsystem of code listed in the following table should be checked. 62
