DIAGNOSIS AND TESTING (Continued)
Special Tool(s)
Traction Battery High-Voltage Lockout and Diagnostic
Tool 418-F207
High-Voltage Insulated Safety Gloves 100-F036 or
equivalent
Face Shield 100-F035 or equivalent
PINPOINT TEST A: DTC C1836 BATTERY TEMPERATURE OUT OF RANGE
A1 CHECK FOR BATTERY TEMPERATURE SENSOR OUT OF
RANGE FAULT
• With key ON, monitor battery control module (BCM) PIDs BATTMP1,
BATTMP2, BATTMP3, and BATTMP4.
• Do any of the BATTMP PIDs indicate YES?
A2 CHECK WIRES TO BATTERY TEMPERATURE SENSOR FOR
OPEN(S)
• 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 performing the following steps. Failure to
follow this warning may result in severe personal injury or death.
• Connect 104-Pin Breakout Box (BOB) to BCM C1986, C1987 using the
BCM/TIM BOB Adapter Cable and Overlay; leave the BCM
disconnected.
• Measure the resistance of the wires indicated below for the battery
temperature sensor in question.
Battery Temperature Sensor #1:
• With key OFF, disconnect upper front pack temperature sensor #1 C1988
and measure the resistance of the BR wire between BOB pin A40 and
temperature sensor #1 C1988.
• With key OFF, measure the resistance of the BR/W wire between BOB
pin A9 and temperature sensor #1 C1988.
Battery Temperature Sensor #2:
• With key OFF, disconnect rear upper pack temperature sensor #2 C1989
and measure the resistance of the GY/BK wire between BOB pin A21
and temperature sensor #2 C1989.
• With key OFF, measure the resistance of the DG wire between BOB pin
A22 and temperature sensor #2 C1989.
Battery Temperature Sensor #3:
• With key OFF, disconnect lower front pack temperature sensor #3 C1981
and measure the resistance of the LG/BK wire between BOB pin A24
and temperature sensor #3 C1981.
• With key OFF, measure the resistance of the R/W wire between BOB
pin A25 and temperature sensor #3 C1981.
Battery Temperature Sensor #4:
