04-18 DIAGNOSTICS - ENGINE CONTROL SYSTEM

04 8 . Run the engine till MIL goes on in one of the following conditions:
• Simulated preset conditions of DTC.

• Simulated failure conditions described by customer.
• Simulated still data status read by diagnostic apparatus.
9 . Use a diagnostic apparatus to read the DTC recorded by ECM.
10 . If DTC records are available while data or functions are normal, refer to the
Diagnostic help – Elimination methods for intermittent failures; If DTC records
are available while data or functions are abnormal, implement diagnostic steps
as per “check list of failure codes” and repair the failure.

CAUTION

• Use a diagnostic apparatus to read and capture the data. Once DTC is stored,
ECM may record the information about the vehicle and driving conditions as
still data.To eliminate the failures, the data capturing function may help
determining whether or not the vehicle is running or stopped when the failure
occurred, whether or not the engine is warm, whether or not the emission control
is nomal, and other data.

Failure code clearing methods
1 . Switch off the ignition.
2 . Connect the analyzer to the diagnostics connector (16-pin) at the lower left of
the dashboard.
3 . Switch on the ignition and the analyzer - use the latest software version.
4 . Select menu items: According to vehicle configuration, select the operation to
clean the fault code.
