TEST ACTION APPLICABILITY
1 Ignition on, engine not running.
With the DRBIIIt, read the Battery Temp Sensor voltage.
Is the voltage above 4.8 volts?
All
Yes → Go To 2
No → Refer to the INTERMITTENT CONDITION symptom in the
Driveability category.
Perform POWERTRAIN VERIFICATION TEST VER-5-NGC.
2 Turn the ignition off.
Disconnect the Battery Temp Sensor harness connector.
Ignition on, engine not running.
Measure the voltage of the Battery Temp Signal circuit in the Battery Temp Sensor
harness connector.
Is the voltage above 5.2 volts?
All
Yes → Repair the short to battery voltage in the Battery Temp Signal
circuit.
Perform POWERTRAIN VERIFICATION TEST VER-5-NGC.
No → Go To 3
