DIAGNOSIS AND TESTING (Continued)
ROUTINE 2: VEHICLE DOES NOT START/VEHICLE QUITS WHILE DRIVING (NIMH VEHICLES)
• 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 less than -30°C (-22°F) still
indicate the same value?
2-8 CHECK TRACTION BATTERY TEMPERATURE SENSORS FOR
OVERTEMPERATURE CONDITION
• With key ON, monitor BCM PIDs TMPSEN1, TMPSEN2, and
TMPSEN3.
• Do any of the TMPSEN PIDs indicate greater than 70°C (158°F)?
2-9 CHECK IF OVERTEMPERATURE STATE IS CAUSED BY AN
ACTUAL OVERTEMPERATURE CONDITION
NOTE: Allow adequate time for vehicle to cool before checking for
temperature decrease.
• While vehicle is connected to the PCS, monitor BCM PIDs TMPSEN1,
TMPSEN2, and TMPSEN3.
• Do the TMPSEN PIDs that were greater than 70°C (158°F)
decrease?
2-10 CHECK BATTERY TEMPERATURE SENSORS
• 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 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 70°C (158°F) still
indicate the same value?

Powertrain Diagnostic Routines Identification
TEST STEP ACTION TO TAKE
Yes = PARK the vehicle indoors in
a cooler environment.
CONNECT the vehicle to a
power control station (PCS)
to allow the traction battery
fans to operate. GO to 2-9.
No = DISCONNECT and
RECONNECT the 12-volt
auxiliary battery negative
cable and RECHECK the
BCM OP PID. If the
BCM OP PID still
indicates 54, REPLACE the
BCM. REFER to
414-03B.
Yes = ALLOW temperature(s) to
decrease below 55°C
(131°F). System OK.
GO to 2-10.
No =
Yes = REPLACE the BCM.
REFER to Section
414-03B.
No = REPLACE the battery
temperature sensor in
question.
