Turn Signal Flasher Assembly -- On-Vehicle Inspection |
1. INSPECT TURN SIGNAL FLASHER CIRCUIT (for LHD) |
Check the power source circuit and ground circuit.
Remove the turn signal flasher relay from the instrument panel junction block.
Measure the voltage and resistance of the instrument panel junction block.
- Standard voltage:
Tester Connection Condition Specified Condition Turn signal flasher relay terminal 1 (IG) - Body ground Ignition switch off Below 1 V Turn signal flasher relay terminal 1 (IG) - Body ground Ignition switch on (IG) 10 to 14 V Turn signal flasher relay terminal 4 (+B) - Body ground Always 10 to 14 V
- Standard resistance:
Tester Connection Specified Condition Turn signal flasher relay terminal 7 (GND) - Body ground Below 1 Ω
