2.
BATTERY TEMPERATURE SENSOR
Turn the ignition off.
Disconnect the Battery Temperature Sensor harness connector.
Ignition on, engine not running.
With the scan tool, read the Battery Temp Voltage value.
Connect a jumper wire between the (K25) Batt Temp Signal circuit and
the (K91) Batt Temp Return circuit in the Battery Temp Sensor harness
connector.
Did the Battery Temp voltage value change from greater than
4.5 volts to less than 1.0 volt with the jumper wire installed?
Yes
>> Replace the Battery Temperature Sensor.
Perform the POWERTRAIN VERIFICATION TEST. (Refer
to 9 - ENGINE - STANDARD PROCEDURE)
No
>> Go To 3
NOTE: Remove the jumper wire before continuing.
3.
(K25) BATT TEMP SIGNAL CIRCUIT SHORTED TO BATTERY VOLTAGE
Turn the ignition off.
Disconnect the C1 FCM harness connector.
Measure the voltage on the (K25) Batt Temp Signal circuit in the Bat-
tery Temp Sensor harness connector.
Is the voltage above 5.2 volts?
Yes
>> Repair the short to battery voltage in the (K25) Batt Temp
Signal circuit.
Perform the POWERTRAIN VERIFICATION TEST. (Refer
to 9 - ENGINE - STANDARD PROCEDURE)
No
>> Go To 4

4.
(K25) BATT TEMP SIGNAL CIRCUIT OPEN
Turn the ignition off.
Measure the resistance of the (K25) Batt Temp Signal circuit from the
Battery Temp Sensor harness connector to the C1 FCM harness con-
nector.
Is the resistance below 5.0 ohms?
Yes
>> Go To 5
No
>> Repair the open in the (K25) Batt Temp Signal circuit.
Perform the POWERTRAIN VERIFICATION TEST. (Refer
to 9 - ENGINE - STANDARD PROCEDURE)
5.
(K91) BATT TEMP RETURN CIRCUIT OPEN
Measure the resistance in the (K91) Batt Temp Return circuit from the
Sensor connector to the C1 FCM harness connector.
Is the resistance below 5.0 ohms?
Yes
>> Go To 6
No
>> Repair the open in the (K91) Batt Temp Return circuit.
Perform the POWERTRAIN VERIFICATION TEST. (Refer
to 9 - ENGINE - STANDARD PROCEDURE)

FRONT CONTROL MODULE
NOTE: Before continuing, check the FCM harness connector terminals for corrosion, damage, or terminal
push out. Repair as necessary.
Using the schematics as a guide, inspect the wire harness and connectors. Pay particular attention to all Power and
Ground circuits.
Were there any problems found?
Yes
>> Repair as necessary.
Perform BODY VERIFICATION TEST-VER 1. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL
MODULES/FRONT CONTROL MODULE - DIAGNOSIS AND TESTING)
No
>> Replace and program the Front Control Module per Service Information.
