DIAGNOSIS AND TESTING (Continued)
ROUTINE 9: VEHICLE DOES NOT CHARGE (NIMH VEHICLES)
TEST STEP ACTION TO TAKE
9-12 CHECK EMERGENCY POWER OFF (EPO) SIGNAL TO
BATTERY CONTROL MODULE (BCM)
•
Remove the traction battery and connect Traction Battery High-Voltage Yes = GO to 9-13.
Lockout and Diagnostic Tool to the traction battery high-voltage two-pin
C3994M.
No = REPLACE the BCM.
WARNING: The traction battery contains high-voltage

shield must be worn when carrying out the following steps. Failure to
follow this warning may result in severe personal injury or death.
•
Connect Traction Battery High Voltage Service Cord to traction battery
support tray in-line C1935F and in-line C1935M.
•
Connect Traction Battery Low Voltage Service Cord to traction battery
support tray in-line C1939F and in-line C1939M.
•
Connect 104-Pin Breakout Box (BOB) to BCM and BCM C1986, C1987
using the BCM/TIM BOB Adapter Cable and Overlay.
•
With key ON, monitor BCM PID EMG PO.
•
Connect a jumper wire between BOB pins A10 and A18.
•
Does the EMG PO PID indicate DISABLE?
9-13 CHECK CIRCUIT 3006 (P/LG) FOR OPEN
•
With key OFF, disconnect contactor box C1982 and measure the Yes = REPLACE the contactor
resistance of the P/LG wire between pin 9 on contactor box C1982 and box. REFER to Section
BOB pin A18. 414-03B .
•
Is the resistance less than 5 ohms?
No = REPAIR the P/LG wire.
9-14 CHECK CHARGER PILOT SIGNAL AT TRACTION BATTERY
CHARGER
•
With key OFF, disconnect traction battery charger C1993. Yes = GO to 9-22.
•
Connect the vehicle to a power control station (PCS). No = GO to 9-15.
•
With key OFF, measure the voltage between pin 5 (LB/R wire) on
traction battery charger C1993 and ground.
•
Is the voltage greater than 10 volts?
9-15 CHECK CHARGER PILOT SIGNAL AT TRACTION BATTERY
SUPPORT TRAY
•
With key OFF, disconnect traction battery support tray in-line C1939 and Yes = GO to 9-18.
connect 104-Pin Breakout Box (BOB) to in-line C1939M using Traction
Battery Low Voltage Service Cord; do not connect Traction Battery Low
Voltage Service Cord to in-line C1939F.
•
Connect the vehicle to a power control station (PCS). No = GO to 9-16.
•
With key OFF, measure the voltage between BOB pin 20 and ground
(BOB pin 65).
•
Is the voltage greater than 10 volts?
9-16 CHECK CIRCUITS 3984 (R) AND 4009 (LB/R) (OUTSIDE OF
TRACTION BATTERY SUPPORT TRAY) FOR OPEN(S)
•
Disengage the locks on the charger inlet connector, push the swing plate Yes = GO to 9-17.
forward, and hold the swing plate in the forward position to access the
terminals on the charger inlet connector.
•
With key OFF, measure the resistance of the R wire between pin 5 on No = REPAIR the wire(s) in
charger inlet C5000 and BOB pin 20. question.
•
With key OFF, measure the resistance of the LB/R wire between pin 5
on traction battery charger C1993 and BOB pin 14.
•
Are the resistances less than 5 ohms?
9-17 CHECK CIRCUITS 3984 (R) AND 4009 (LB/R) (OUTSIDE OF
TRACTION BATTERY SUPPORT TRAY) FOR SHORT(S) TO
GROUND
