MALFUNCTION INDICATOR LAMP (MIL) CHECK
Refer to the same item in Section 6 / 6-1 for checking procedure.
ªO / D OFFº LAMP CHECK
1) Check that O / D cut switch button is at OFF position (pushed).
2) Turn ignition switch ON.
3) Check that ªO / D OFFº lamp lights for about 2 ± 4 sec. and then goes OFF.
If anything faulty is found, advance ªDiagnostic flow table B-1 or B-2º O / D OFF ªLAMP CIRCUIT CHECKº.
ªPOWERº LAMP CHECK
1) Check that Power / Normal change switch button is at Normal position.
2) Turn ignition switch ON.
3) Check that ªPowerº Lamp light for 2 ± 4 sec. and then goes OFF.
If anything faulty is found, advance ªDiagnostic flow table B-3 or B-4 ªPOWERº LAMP CIRCUIT CHECK 2.
