READING FAULT CODES
•
Stored fault codes are also called permanent fault
codes. These fault codes turn on the fault status
light (MIL) when a fault affects emissions.
•
Inactive fault codes, also called mature fault codes
or continuous fault codes, are generated by faults
detected by the control unit during the present or
previous cycle, but which are still not considered to
be serious. Pending fault codes do not turn on the
fault status light and are not stored in the memory.

The engine and ignition must be switched off when
doing this step. Do not start the engine.
•
Read and note the fault codes before doing this step.
•
Switch on the ignition again when the fault codes
are erased and check if any fault code is generated
again. If so, troubleshoot and correct. Erase the fault
codes afterwards.
