DIAGNOSTIC TROUBLE CODE CHECK
1. Turn the ignition switch ON, but do not start the engine.
2. Push in the O/D main switch to ON.
HINT: Warning and diagnostic trouble codes can be read only when the O/D main switch is ON. If it is OFF, the O/D OFF indicator light up will light continuously and will not blink.

4. Read the diagnostic trouble code indicated by the number of times the O/D OFF indicator light blinks.
HINT: If the system is operating normally, the light will blink 2 times per second.
Diagnostic trouble code "42" is shown as an example.
HINT: When 2 or more trouble codes are stored in memory, the lower-numbered code is displayed first. If no diagnostic trouble code is output, or if a diagnostic trouble code is output even though no diagnostic trouble code output operation is performed, check the TE1 terminal circuit.
