• BATTERY TEMP SENSOR
• INTERMITTENT CONDITION

DIAGNOSTIC PROCEDURE

1. Remove the temperature sensor and reconnect the wiring harness connector to the sensor. Monitor DRBIII®, while heating the sensor with an external heat source (DO NOT USE OPEN FLAME). Does the reading from the sensor increase at least 5 degrees F. on the DRBIII®?
   Yes --> Refer to the SYMPTOM: INTERMITTENT CONDITION Symptom (Diagnostic Procedure). Perform POWERTRAIN VERIFICATION TEST VER - 4 (DIESEL).
   No --> Replace the battery temperature sensor. Perform POWERTRAIN VERIFICATION TEST VER - 4 (DIESEL).
