TEST STEP ACTION TO TAKE
No = REPLACE the battery
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.
•
With key OFF, disconnect the battery temperature sensor in question and
one of the other temperature sensors.
•
Connect jumper wires between the connector for the temperature sensor
in question and the known good temperature sensor that was
disconnected.
•
With key ON, monitor BCM PIDs TMPSEN1, TMPSEN2, and
TMPSEN3.
•
Does the TMPSEN PID that indicated greater than 55
°
C (131
°
F) still
indicate the same value?
5-5 CHECK TRACTION BATTERY TEMPERATURE SENSORS FOR
UNDERTEMPERATURE CONDITION
•
With key ON, monitor BCM PIDs TMPSEN1, TMPSEN2, and Yes = PARK the vehicle indoors in
TMPSEN3. a warmer environment.
CONNECT the vehicle to a
power control station (PCS)
to allow self-heating. GO to
5-6.
•
Do any of the TMPSEN PIDs indicate less than -25
°
C (-13
°
F)?
No = DISCONNECT and
RECONNECT the 12-volt
auxiliary battery negative
cable and RECHECK the
BCM OP PID. If the
BCM OP PID still
indicates 68, REPLACE the
BCM. REFER to Section
414-03B .
5-6 CHECK IF UNDERTEMPERATURE STATE IS CAUSED BY AN
ACTUAL UNDERTEMPERATURE CONDITION
NOTE: Allow adequate time for vehicle to warm before checking for

TMPSEN2, and TMPSEN3.
•
Do the TMPSEN PIDs that were less than -25
°
C (-13

F) increase?
No = GO to 5-7.
5-7 CHECK BATTERY TEMPERATURE SENSORS
•
Remove the traction battery and connect Traction Battery High-Voltage Yes = REPLACE the BCM.
