DIAGNOSIS AND TESTING (Continued)
ROUTINE 9: VEHICLE DOES NOT CHARGE (NIMH VEHICLES)
TEST STEP ACTION TO TAKE
9-28 CHECK CIRCUIT 3009 (O/R) (OUTSIDE OF TRACTION
BATTERY SUPPORT TRAY) FOR OPEN
•
With key OFF, disconnect traction battery support tray in-line C1939 and Yes = GO to 9-29.
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.
•
With key OFF, disconnect traction battery charger C1993. No = REPAIR the O/R wire.
•
With key OFF, measure the resistance of the O/R wire between pin 7 on
traction battery charger C1993 and BOB pin 56.
•
Is the resistance less than 5 ohms?
9-29 CHECK CIRCUIT 3009 (O/R) (OUTSIDE OF TRACTION
BATTERY SUPPORT TRAY) FOR SHORT TO GROUND
•
With key OFF, measure the resistance between BOB pins 56 and ground Yes = GO to 9-30.
(BOB pin 65).
•
Is the resistance greater than 10,000 ohms?
No = REPAIR the O/R wire.
9-30 CHECK CIRCUIT 3009 (O/R) (INSIDE OF TRACTION
BATTERY SUPPORT TRAY) FOR OPEN
•
Disconnect BOB from in-line C1939M, remove the traction battery, and Yes = GO to 9-31.
connect Traction Battery High-Voltage Lockout and Diagnostic Tool to
the traction battery high-voltage two-pin C3994M.
No = REPAIR the O/R wire.
WARNING: The traction battery contains high-voltage
components and wiring. High-voltage insulated safety gloves and face
shield must be worn when carrying out the following steps. Failure to
follow this warning may result in severe personal injury or death.
•
Connect BOB to traction battery support tray in-line C1939F using
Traction Battery Low Voltage Service Cord; do not connect Traction
Battery Low Voltage Service Cord to in-line C1939M.
•
With key OFF, disconnect BCM C1986.
•
Measure the resistance of the O/R wire between pin 6 on BCM C1986
and BOB pin 56.
•
Is the resistance less than 5 ohms?
9-31 CHECK CIRCUIT 3009 (O/R) (INSIDE OF TRACTION
BATTERY SUPPORT TRAY) FOR SHORT TO GROUND
•
With key OFF, measure the resistance between BOB pins 56 and ground Yes = REPLACE the traction
(BOB pin 65). battery charger. REFER to
Section 414-03B .
•
Is the resistance greater than 10,000 ohms?
No = REPAIR the O/R wire.
9-32 CHECK CHARGER CORD INPUT STATUS
NOTE: Verify the power control station (PCS) charger cord is connected
Yes = REPLACE the traction
to the charger inlet before carrying out this test step.

•
With key OFF, connect the PCS to the charger inlet connector and
Section 414-03B .
monitor BCM PID CHGCORD.
•
Does the CHGCORD PID indicate IN?
No = GO to 9-35.
9-33 CHECK CHARGER INLET
•
With key OFF, disconnect in-line C1969 (located on the chassis next to Yes = GO to 9-34.
the right headlamp inside the underhood compartment).
•
With key OFF, connect the PCS to the charger inlet connector and No = REPLACE the charger inlet.
measure the resistance between the Y wire and BK wire on in-line REFER to Section
C1969F. 414-03B .
•
Is the resistance less than 5 ohms?
