DIAGNOSIS AND TESTING (Continued)
PINPOINT TEST T: HI BEAM INDICATOR DOES NOT OPERATE
• Turn the headlamp switch to the ON position, set the multi-function
switch to the high beam position and measure the voltage between pin 1
(LG/BK wire) on instrument cluster C216 and ground.
• Is the voltage greater than 10 volts?
T2 CHECK GROUND TO INSTRUMENT CLUSTER
• With key OFF, measure the resistance between pin 2 (BK wire) on
instrument cluster C216 and ground.
• Is the resistance less than 5 ohms?
T3 CHECK HI BEAM INDICATOR BULB
• With key OFF, remove and check the hi beam indicator bulb.
• Is the bulb OK?
PINPOINT TEST U: LEFT TURN INDICATOR DOES NOT OPERATE
U1 CHECK POWER TO INSTRUMENT CLUSTER
• With key OFF, disconnect instrument cluster C216.
• With key ON, set the multi-function switch to the left turn position and
measure the voltage between pin 5 (LG/W wire) on instrument cluster
C216 and ground.
• Does the voltage vary from 0 to greater than 10 volts?
U2 CHECK GROUND TO INSTRUMENT CLUSTER
• With key OFF, measure the resistance between pin 2 (BK wire) on
instrument cluster C216 and ground.
• Is the resistance less than 5 ohms?
U3 CHECK LEFT TURN INDICATOR BULB
• With key OFF, remove and check the left turn indicator bulb.
• Is the bulb OK?
PINPOINT TEST V: RIGHT TURN INDICATOR DOES NOT OPERATE
V1 CHECK POWER TO INSTRUMENT CLUSTER
• With key OFF, disconnect instrument cluster C214.
• With key ON, set the multi-function switch to the right turn position and
measure the voltage between pin 8 (W/LB wire) on instrument cluster
C214 and ground.
• Does the voltage vary from 0 to greater than 10 volts?
V2 CHECK GROUND TO INSTRUMENT CLUSTER
• With key OFF, disconnect instrument cluster C216 and measure the
resistance between pin 2 (BK wire) on instrument cluster C216 and
ground.
• Is the resistance less than 5 ohms?
V3 CHECK RIGHT TURN INDICATOR BULB
• With key OFF, remove and check the right turn indicator bulb.
• Is the bulb OK?
