DIAGNOSIS AND TESTING (Continued)
ROUTINE 11: VEHICLE CHARGING TAKES LONGER THAN NORMAL TO REACH FULL STATE OF
CHARGE (SOC) (NIMH VEHICLES)
• With key OFF and vehicle on-charge, monitor BCM PID BCM OP. • Does the BCM OP PID indicate 118 (limited operating strategy
charge-battery under temperature)?
11-2 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 below -15°C (5°F)?
11-3 CHECK TEMPERATURE DIFFERENCE BETWEEN BATTERY
TEMPERATURE SENSORS
• With key ON, monitor battery control module (BCM) PIDs TMPSEN1,
TMPSEN2, and TMPSEN3.
• Is there a temperature difference of greater than 20°C (36°F)
between the temperature sensor that is below -15°C (5°F), and the
other temperature sensors?
11-4 CHECK BATTERY TEMPERATURE SENSOR
• Remove the traction battery and connect Traction Battery High-Voltage
Lockout and Diagnostic Tool to the traction battery high-voltage two-pin
C3994M.
• Connect Traction Battery High Voltage Service Cord to traction battery
support tray in-line C1935F and in-line C1935M.
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 battery control module (BCM) PIDs TMPSEN1,
TMPSEN2, and TMPSEN3.
• Does the TMPSEN PID that indicated below -15°C (5°F) and still
indicate below -15°C (5°F)?
Powertrain Diagnostic Routines Identification
TEST STEP ACTION TO TAKE
No = INFORM customer the
vehicle may take longer to
charge due to low
environmental temperature
conditions.
GO to 11-3.
Yes =
If any of the TMPSEN PIDs
are below -15°C (5°F),
PARK the vehicle in a
warm environment to warm
up above -15°C (5°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 118, REPLACE
the BCM. REFER to
Section 414-03B.
Yes = GO to 11-4.
No = PARK the vehicle in a
warm environment to warm
the vehicle above -15°C
(5°F) for the temperature
sensor in question.
Yes = REPLACE the BCM.
REFER to Section 414-03B
No = REPLACE the battery
temperature sensor in
question.
