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
t, read the Battery Temp Sensor voltage.
Is the voltage below 1.0 volt?
All
Yes
→ Replace the Battery Temp Sensor.
Perform POWERTRAIN VERIFICATION TEST VER - 5.
No
→ Go To 4
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 (K118) 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?
All
Yes
→ Go To 5
No
→ Repair the open in the (K118) Battery Temp Signal circuit.
Perform POWERTRAIN VERIFICATION TEST VER - 5.
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 (K167) 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?
All
Yes
→ Go To 6
No
→ Repair the open in the (K167) Sensor ground circuit.
Perform POWERTRAIN VERIFICATION TEST VER - 5.

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.
