DIAGNOSIS AND TESTING (Continued)
PINPOINT TEST Y: DOOR AJAR INDICATOR DOES NOT OPERATE PROPERLY
• With key ON, measure the voltage between pin 1 (LB wire), pin 12 (LB
wire) on instrument cluster C215 and ground.
• Is the voltage greater than 10 volts?
Y6 CHECK CIRCUIT 627 (BK/O) FOR OPEN
• With key OFF, disconnect GEM C221 and measure the resistance of the
BK/O wire between pin 9 on instrument cluster C215 and pin 9 on GEM
C221.
• Is the resistance less than 5 ohms?
Y7 CHECK CIRCUIT 627 (BK/O) FOR SHORT TO GROUND
• With key OFF, measure the resistance between pin 9 (BK/O wire) on
instrument cluster C215 and ground.
• Is the resistance greater than 10,000 ohms?
Y8 CHECK DOOR AJAR INDICATOR CONTROL CIRCUIT FOR
SHORT TO POWER
• With key OFF, disconnect instrument cluster C215.
• With key ON, measure the voltage between pin 9 (BK/O wire) on
instrument cluster C215 and ground.
• Is the voltage greater than 0 volts?
Y9 CHECK CIRCUIT 627 (BK/O) FOR SHORT TO POWER
• With key OFF, disconnect GEM C221.
• With key ON, measure the voltage between pin 9 (BK/O wire) on
instrument cluster C215 and ground.
• Is the voltage greater than 0 volts?
PINPOINT TEST Z: SEAT BELT INDICATOR DOES NOT OPERATE PROPERLY
Z1 CHECK IGNITION SWITCH STATES
• Use New Generation STAR (NGS) Tester to monitor the PID
IGN GEM while turning the ignition switch through the START, RUN,
OFF, and ACC positions.
• Do the PID values agree with the ignition switch position?
Z2 RETRIEVE DIAGNOSTIC TROUBLE CODES (DTCs)
• Retrieve and document continuous DTCs, clear continuous DTCs, and
carry out on-demand self-test.
• Are any DTCs recorded?
Z3 VERIFY SEAT BELT WARNING CHIME OPERATION
