Pinpoint Test 1: The Turn Signal Lamps Are Inoperative

PINPOINT TEST 1: THE TURN SIGNAL LAMPS ARE INOPERATIVE

Normal Operation

The SJB provides voltage to the indicator flasher relay through circuit (Y/V). The indicator flasher relay routes the voltage to the multifunction switch through circuit (V/BR). When the multifunction switch is placed in the LH TURN position, the multifunction switch routes the voltage to the LH front and rear turn lamps through circuits (GY/Y). When the multifunction switch is placed in the RH TURN position, the multifunction switch routes the voltage to the RH front and rear turn lamps through circuits (V/W). Ground for the indicator flasher relay is provided through circuit (B/Y).

This pinpoint test is intended to diagnose the following:
- Fuse
- Wiring, terminals or connectors
- Indicator flasher relay
- Multifunction switch
- (SJB)

CAUTION:Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.
