Trouble Diagnosis
Trouble diagnosis
Trouble diagnosis can be carried out by releasing the diagnostic switch. The results of the diagnosis are displayed by the diagnosis light (Engine Control warning light and Overheat warning light) (flashing light: Diagnosis Display Code). [Dealer mode]
When the Overheat warning light flashes, the buzzer also sounds at the same time.
Engine Control warning light: displays present trouble
Overheat warning light: displays the past trouble (*)
NOTE (*):
- To carry out analysis of past troubles, the system is equipped with a diagnostic memory function. This function stores in the memory any failure signals for abnormality that occurred during travel. It acts to replay these signals when carrying out analysis of the trouble.
The signals stored in the memory are retained even when the ignition key switch is turned OFF.
- Normally, the Overheat warning light lights up when the engine overheats or when the coolant level becomes too low. However, when the diagnostic switch is released, it displays the result of the diagnosis of past troubles in the MD-TICS system.
The overheat warning function is not incorporated in the control unit.
