DIAGNOSIS AND TESTING (Continued)
ROUTINE 9: VEHICLE DOES NOT CHARGE (NIMH VEHICLES)
9-34 CHECK CIRCUIT 3404 (Y) (OUTSIDE OF TRACTION
BATTERY SUPPORT TRAY) FOR OPEN
• With key OFF, disconnect traction battery support tray in-line C1939 and Yes =
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, measure the resistance of the Y wire between BOB pin
54 and in-line 1969M.
• Is the resistance less than 5 ohms?
9-35 CHECK CIRCUIT 3404 (Y) (INSIDE OF TRACTION BATTERY
SUPPORT TRAY) FOR OPEN
• Disconnect BOB from in-line C1939M, remove the traction battery, and
connect Traction Battery High-Voltage Lockout and Diagnostic Tool to
the traction battery high-voltage two-pin C3994M.
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 C1987.
• Measure the resistance of the Y wire between pin 12 on BCM C1987
and BOB pin 54.
• Is the resistance less than 5 ohms?
ROUTINE 10: VEHICLE CHARGING TAKES LONGER THAN NORMAL TO REACH FULL STATE OF
CHARGE (SOC) (LEAD ACID VEHICLES)
10-1 CHECK STATUS OF BATTERY CONTROL MODULE (BCM)
OPERATING STATE
NOTE: Following charging, wait approximately five minutes to allow the
BCM OP PID to be set.
• Connect the vehicle to a power control station (PCS) and press the
START button to begin charging.
• With key OFF and vehicle on-charge, monitor BCM PID BCM OP. • Does the BCM OP PID indicate 112 (limited operating strategy
charge-high battery temperature)?
10-2 CHECK TRACTION BATTERY TEMPERATURE SENSORS FOR
OVERTEMPERATURE CONDITION
• With key ON, monitor BCM PIDs TMPSEN1, TMPSEN2, TMPSEN3,
and TMPSEN4.

ACTION TO TAKE
GO to 9-35.
No = REPAIR the Y wire.
Yes = REPLACE the BCM.
REFER to Section
414-03B.
No = REPAIR the Y wire.
ACTION TO TAKE
GO to 10-2.
Yes =
No = INFORM customer the
vehicle may take longer to
charge due to high
environmental temperature
conditions.
GO to 10-3.
Yes =
If all TMPSEN PIDs are
between 50°C (122°F) and
60°C (140°F), PARK the
vehicle in a cool
environment to cool down
below 50°C (122°F).
