ACTION TO TAKE
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,
