4-8 CHECK BATTERY TEMPERATURE SENSOR
•
Remove the traction battery and connect Traction Battery High-Voltage Yes = REPLACE the BCM.
Lockout and Diagnostic Tool to the traction battery high-voltage two-pin REFER to Section
C3994M. 414-03A .
•
Connect Traction Battery High Voltage Service Cord to traction battery No = REPLACE the battery
support tray in-line C1935F and in-line C1935M. temperature sensor in
question.
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 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, TMPSEN3,
and TMPSEN4.
•
Does the TMPSEN PID that indicated less than -20
°
C (-4
°
F) still
indicate -20
°
C (-4

F)?
4-9 CHECK STATUS OF TRACTION BATTERY MODULES BY
CARRYING OUT THE BATTERY MODULE DIAGNOSTIC TEST
•
With key ON, carry out the Battery Module Diagnostic Test. Refer to the Yes = REPLACE the battery
procedure in Traction Battery System Section 414-03A . module(s) in question.
REFER to Section
414-03A .
•
Does the Battery Module Diagnostic Test indicate to replace any

4-10 CHECK MOTOR TEMPERATURE
•
Drive the vehicle until the vehicle runs at reduced power. Yes = GO to 4-11.
•
With key ON, monitor the traction inverter motor (TIM) PID TIMTEMP No = GO to 4-12.
and note the temperature.
•
Is the temperature greater than 170
°
C (338
°
F)?
4-11 CHECK MOTOR TEMPERATURE SENSOR
•
With key OFF, disconnect motor/transaxle C4993 and connect Electric Yes = REPLACE the
Motor/Transaxle Test Box. motor/transaxle. REFER to
Section 303-01.
•
Measure the resistance between the motor temperature ports on the test No = GO to 4-13.
