Normal Operation

When the multifunction switch is in the LH TURN position, voltage is sent from the multifunction switch to the instrument cluster through circuit (V/W), and the LH turn signal indicator flashes on and off. The instrument cluster provides the bulb ground through circuit (B/Y).

This pinpoint test is intended to diagnose the following:

Wiring, terminals or connectors
Instrument cluster
CAUTION:
- Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.

LH TURN SIGNAL INDICATOR PINPOINT TEST 12

PINPOINT TEST 12		THE LH TURN SIGNAL INDICATOR IS NEVER ON
STEP	INSPECTION		ACTION
1	CHECK THE LH TURN SIGNAL OPERATION Key in ON position. Operate the LH turn signal. Does the LH turn signal operate?	Yes	Go to next step.
1		No	See TURN SIGNAL AND HAZARD LAMPS to continue diagnosis of the turn signals.
2	CHECK CIRCUIT (V/W) FOR VOLTAGE Key in OFF position. Disconnect: Instrument Cluster connector 0922-102. Key in ON position. Place the multifunction switch in the LH turn signal position. Measure the voltage between the instrument cluster 0922-101 pin 12, circuit (V/W), harness side and ground. Does the voltage vary from 0 to greater than 10 volts?	Yes	Go to next step.
2		No	REPAIR the circuit. TEST the system for normal operation.
3	CHECK THE GROUND TO THE INSTRUMENT CLUSTER Key in OFF position. Measure the resistance between the instrument cluster 0922-102 pin 1, circuit (B/Y), harness side and ground. Is the resistance less than 5 ohms?	Yes	Go to next step.
3		No	REPAIR the circuit. TEST the system for normal operation.
4	CHECK FOR CORRECT INSTRUMENT CLUSTER OPERATION Disconnect all the instrument cluster connectors. Check for: corrosion damaged pins pushed-out pins incorrectly installed bulb sockets burnt-out bulbs Connect all the instrument cluster connectors and make sure they seat correctly. Operate the system and verify the concern is still present. Is the concern still present?	Yes	INSTALL a new instrument cluster. See INSTRUMENT CLUSTER . TEST the system for normal operation.
4		No	The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector.
