DIAGNOSIS AND TESTING (Continued)
PINPOINT TEST F: DISTANCE TO EMPTY (DTE) GAUGE DOES NOT OPERATE OR INDICATES
INCORRECT DISTANCE TO EMPTY
TEST STEP ACTION TO TAKE
•
Enter the active command mode DISTANCE TO EMPTY GAUGE and No = REPAIR the Y/W wire
set the active command DTE G to 30%. between instrument cluster
•
Set the multimeter to the frequency setting and measure the frequency C214 and IAA module
between pin 10 (Y/W wire) on instrument cluster C214 and ground. C1945.
•
Is the frequency greater than 70 Hz?
F5 CHECK CIRCUIT 3047 (Y/W) FOR SHORT TO GROUND
•
With key OFF, measure the resistance between BOB pin 98 and ground Yes = GO to F6.
(BOB pin 80).
•
Is the resistance greater than 10,000 ohms?
No = REPAIR the Y/W wire
between instrument cluster
C214 and IAA module
C1945.
F6 CHECK CIRCUIT 3047 (Y/W) FOR SHORT TO POWER
•
With key ON, measure the resistance between BOB pin 98 and ground Yes = REPAIR the Y/W wire
(BOB pin 80). between instrument cluster
C214 and IAA module
C1945.
•
Is the voltage greater than 0 volts?
No = GO to F7.
F7 CHECK POWER TO INSTRUMENT CLUSTER
•
With key OFF, disconnect instrument cluster C215. Yes = REPLACE the instrument
cluster.
•
With key ON, measure the voltage between pin 12 (BK/LG wire) on No = GO to F8.
instrument cluster C214 and pin 6 (BK/W wire) on instrument cluster
C215.
•
Is the voltage greater than 10 volts?
F8 CHECK GROUND TO INSTRUMENT CLUSTER
•
With key OFF, measure the resistance between pin 6 (BK/W wire) on Yes = REPAIR circuit 3049
instrument cluster C215 and ground. (BK/LG wire).
•
Is the resistance less than 5 ohms?
No = REPAIR the BK/W wire.
PINPOINT TEST G: MOTOR ENABLED GAUGE DOES NOT OPERATE OR INDICATES WAY ABOVE THE
ON MARK
TEST STEP ACTION TO TAKE
G1 IDENTIFY SYMPTOM
•
Turn the ignition key to the START position and identify the symptom. Yes = GO to G2.
•
Does the motor enabled gauge indicate OFF?
No = GO to G8.
G2 CHECK MOTOR ENABLED GAUGE
•
Enter the interface adapter assembly (IAA) module active command Yes = System OK. CHECK wiring
mode INSTRUMENTATION CONTROL and set the active commands for intermittent connections.
GAUGE PWR to ON and MOTOR ENA to ON.
•
Does the motor enabled gauge indicate ON?
No = GO to G3.
G3 CHECK GAUGE DRIVE SIGNAL FROM INTERFACE ADAPTER
ASSEMBLY (IAA) MODULE
•
Connect 104-Pin Breakout Box (BOB) to the IAA module and IAA Yes = GO to G5.
module C1945.
•
With key ON, measure the voltage between BOB pin 15 and ground No = GO to G4.
(BOB pin 80).
•
Is the voltage greater than 10 volts?
G4 CHECK CIRCUIT 3405 (GY/R) FOR SHORT TO GROUND
