Side Marker/Hazard Flasher System

Turn Signal/Hazard Relay Input Test

CAUTION:
•   All SRS electrical wiring harnesses are covered with yellow outer insulation.
•   Before disconnecting the SRS wire harness, install the short connector on the airbag (see page 23-273).
•   Replace the entire affected SRS harness assembly if it has an open circuit or damaged wiring.

1. Remove the turn signal/hazard relay from the under-dash fuse box.
2. Make the following input tests at the relay holder terminals.
3. If all tests prove OK, but the relay fails to work, replace the turn signal/hazard relay.

No.	Terminal	Test condition	Test: desired result	Possible cause (if result is not obtained)
1	E	Under all conditions.	Check for continuity to ground: there should be continuity.	•   Poor ground (G201, G401). •   An open in the BLK wire.
2	B	Ignition switch ON.	Check for voltage to ground: there should be battery voltage.	•   Blow No. 15 (10 A) fuse. •   An open in the YEL or GRN/WHT wire. •   Faulty hazard switch.
		Hazard switch ON.	Check for voltage to ground: there should be battery voltage.	•   Blown No. 43 (10 A) fuse. •   An open in the WHT/GRN or GRN/WHT wire. •   Faulty hazard switch.
3	L	Hazard switch ON and connect the B terminal to the L ter- minal.	Hazard lights should come on.	•   Poor ground (G201, G301, G401, G553, G554, G771), •   Faulty hazard switch. •   An open in the GRN/RED, GRN/YEL, GRN/BLU or BLK wire.
		Ignition switch ON and turn signal switch in R or L and connect the B terminal to the L terminal.	R or L turn signal lights should come on.	•   Faulty turn signal switch.
