DIAGNOSIS AND TESTING (Continued)
PINPOINT TEST C: TRACTION BATTERY STATE OF CHARGE (SOC) GAUGE DOES NOT OPERATE,
INDICATES THE INCORRECT SOC, OR ALWAYS INDICATES F (FULL)
TEST STEP ACTION TO TAKE
•
Enter the interface adapter assembly (IAA) module active command Yes = GO to C3.
mode BATTERY STATE OF CHARGE and set the active command
BAT SOC to 50%.
•
Does the traction battery SOC gauge indicate above the E (empty)
No = GO to C4.
mark?
C3 CHECK TRACTION BATTERY SOC GAUGE FOR CORRECT
SOC
•
Set the active command BAT SOC to the following percentages and Yes = System OK. CHECK wiring
verify the traction battery SOC gauge operation: for intermittent connections.
Percentage/SOC
No = REPLACE the instrument
cluster.
— 15% = E (empty)
— 30% = 0.25 mark
— 50% = .50 mark
— 65% = .75 mark
— 75% = F (full)
•
Is the traction battery SOC gauge OK?
C4 CHECK INTERFACE ADAPTER ASSEMBLY (IAA) MODULE
•
Connect 104-Pin Breakout Box (BOB) to the IAA module and IAA Yes = REPLACE the IAA module.
module C1945. REFER to Section 412-04.
•
With key ON, connect a jumper wire between BOB pins 21 and 75. No = GO to C5.
•
Does the traction battery SOC gauge indicate greater than F (full)?
C5 CHECK CIRCUIT 3048 (O) FOR OPEN
•
With key OFF, disconnect instrument cluster C215 and measure the Yes = REPLACE the instrument
resistance of the O wire between pin 4 on instrument cluster C215 and cluster.
BOB pin 21.
•
Is the resistance less than 5 ohms?
No = REPAIR the O wire.
C6 CHECK POWER TO INSTRUMENT CLUSTER
•
With key OFF, disconnect instrument cluster C215. Yes = GO to C8.
•
With key ON, measure the voltage between pin 11 (BK/LG wire) and No = GO to C7.
pin 6 (BK/W wire) on instrument cluster C215.
•
Is the voltage greater than 10 volts?
C7 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.
C8 CHECK CIRCUIT 3048 (O) FOR SHORT TO POWER
•
Connect 104-Pin Breakout Box (BOB) to the IAA module C1945; leave Yes = REPAIR the O wire.
IAA module disconnected.
•
With key ON, measure the voltage between BOB pin 21 and ground No = GO to C9.
(BOB pin 80).
•
Is the voltage greater than 0 volts?
C9 CHECK INSTRUMENT CLUSTER
•
With key OFF, reconnect instrument cluster C215. Yes = REPLACE the IAA module.
REFER to Section 412-04.
•
With key OFF, connect BOB to IAA module; leave BOB connected to No = REPLACE the instrument
IAA module C1945. cluster.
•
With key ON, connect a jumper wire between BOB pin 21 and ground
(BOB pin 80).
•
Does the traction battery SOC gauge indicate E (empty)?
