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 C1991 and C1993. No = REPAIR the wire(s) in
•
With key OFF, measure the resistance of the O/LB wire between pin 4 question.
on traction battery charger C1991 and BOB pin 61.
•
With key OFF, measure the resistance of the LB/R wire between pin 2
on traction battery charger C1993 and BOB pin 28.
•
Are the resistances less than 5 ohms?
9-24 CHECK CIRCUITS 3002 (O/LB) AND 3990 (LB/R) (OUTSIDE OF

Are the resistances greater than 10,000 ohms?
No = REPAIR the wire(s) in
question.
9-25 CHECK CIRCUITS 3002 (O/LB) AND 3990 (LB/R) (INSIDE OF
TRACTION BATTERY SUPPORT TRAY) FOR OPEN
•
Disconnect BOB from in-line C1939M, remove the traction battery, and Yes = GO to 9-26.
connect Traction Battery High-Voltage Lockout and Diagnostic Tool to
the traction battery high-voltage two-pin C3994M.
•
Connect BOB to traction battery support tray in-line C1939F using No = REPAIR the wire(s) in
Traction Battery Low Voltage Service Cord; do not connect Traction question.
Battery Low Voltage Service Cord to in-line C1939M.
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.
•
With key OFF, disconnect BCM C1986 and C1987.
•
Measure the resistance of the O/LB wire between pin 5 on BCM C1987
and BOB pin 61.
•
Measure the resistance of the LB/R wire between pin 35 on BCM C1986
and BOB pin 28.
•
Are the resistances less than 5 ohms?
9-26 CHECK CIRCUITS 3002 (O/LB) AND 3990 (LB/R) (INSIDE OF
TRACTION BATTERY SUPPORT TRAY) FOR SHORT(S) TO
GROUND
•
With key OFF, measure the resistance between BOB pins 28, 61 and Yes = REPLACE the traction
ground (BOB pin 65). battery charger. REFER to
Section 414-03B .
•
Are the resistances greater than 10,000 ohms?
No = REPAIR the wire(s) in
question.
9-27 VERIFY POWER CONTROL STATION (PCS) OPERATION
