INSPECTION PROCEDURE
- Inspect the fuses and bulbs for circuits related to this system before performing the following inspection procedure.
1.CHECK TURN SIGNAL LIGHT FUNCTION |
Check that the turn signal lights blink.
ResultResult | Proceed to |
All turn signal lights do not blink | A |
LH side turn signal light does not blink | B |
RH side turn signal light does not blink | C |
2.CHECK HARNESS AND CONNECTOR (TURN SIGNAL FLASHER ASSEMBLY - BATTERY AND BODY GROUND) |
Disconnect the turn signal flasher connector.
Measure the voltage according to the value(s) in the table below.
- Standard Voltage:
Tester Connection | Condition | Specified Condition |
E19-1 (IG) - Body ground | Ignition switch ON | 11 to 14 V |
Ignition switch off | Below 1 V |
E19-4 (B) - Body ground | Always | 11 to 14 V |
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
Tester Connection | Condition | Specified Condition |
E19-7 (E) - Body ground | Always | Below 1 Ω |
