16-111prose procedureBracketed ground designations [G201, G401] apply to RHD models.
Turn Signal/Hazard Relay Input Test
Remove the dashboard lower panel, then remove the turn signal/hazard relay from the dash fuse box. Make the following input tests at the relay holder pins. If all tests prove OK, but the relay fails to work, replace the turn signal/hazard relay.
1
TerminalE
Test conditionUnder all conditions.
Test: desired resultCheck for continuity to ground: should be continuity.
Possible cause (if result is not obtained)Poor ground (G301, G401 [G201, G401]). An open in the BLK wire.
2
TerminalB
Test conditionIgnition switch ON.
Test: desired resultCheck for voltage to ground: should be battery voltage.
Possible cause (if result is not obtained)Blown No.1 (10A) fuse. An open in the YEL or GRN/WHT wire. Faulty hazard switch.
3
TerminalB and L
Test conditionHazard switch ON and connect the B terminal to the L terminal.
Test: desired resultHazard lights should come on.
