3 Turn the ignition off.
Disconnect the Battery Temp harness connector.
Connect a jumper wire between the Battery Temp Signal circuit and the Sensor
ground circuit in the Battery Temp harness connector.
Ignition on, engine not running.
With the DRBIII , read the Battery Temp Sensor voltage.
Is the voltage below 1.0 volt?
Yes → Replace the Battery Temp Sensor.
→ Go To 4
No
4 Turn the ignition off.
Disconnect the Battery Temp Sensor harness connector.
Disconnect the PCM harness connector.
CAUTION: DO NOT PROBE THE PCM HARNESS CONNECTORS. PROBING
THE PCM HARNESS CONNECTORS WILL DAMAGE THE PCM TERMI-
NALS RESULTING IN POOR TERMINAL TO PIN CONNECTION. INSTALL
MILLER SPECIAL TOOL #8815 TO PERFORM DIAGNOSIS.
Measure the resistance of the Battery Temp Signal circuit from the Battery Temp
Sensor harness connector to the appropriate terminal of special tool #8815.
Is the resistance below 5.0 ohms?
Yes → Go To 5
→ Repair the open in the Battery Temp Signal circuit.
No
5 Turn the ignition off.
Disconnect the Battery Sensor harness connector.
Disconnect the PCM harness connector.
CAUTION: DO NOT PROBE THE PCM HARNESS CONNECTORS. PROBING
THE PCM HARNESS CONNECTORS WILL DAMAGE THE PCM TERMI-
NALS RESULTING IN POOR TERMINAL TO PIN CONNECTION. INSTALL
MILLER SPECIAL TOOL #8815 TO PERFORM DIAGNOSIS.
Measure the resistance of the Sensor ground circuit from the Battery Temp Sensor
harness connector to the appropriate terminal of special tool #8815.
Is the resistance below 5.0 ohms?
Yes → Go To 6
→ Repair the open in the Sensor ground circuit.
No
6 NOTE: Before continuing, check the PCM harness connector terminals for
corrosion, damage, or terminal push out. Repair as necessary.
If there are no possible causes remaining, view repair.
