INTERMITTENT NO CRANK DURING COLD TEMPS

TECHNICAL SERVICE BULLETIN

INTERMITTENT NO CRANK DURING COLD AMBIENT TEMPERATURES (REPLACE THEFT DETERRENT RELAY)

APPLICATION

Model(s): 1997 Saturn

Group: Electrical - 01

Corporation No.: 688105

Bulletin No.: 97-T-01

Date: January, 1997

VEHICLES AFFECTED

1997 Saturns built before and including VIN VZ259806.

CONDITION

Vehicles that are subjected to cold ambient temperatures of 0° C (32° F) or lower for extended periods of time may intermittently exhibit a no crank condition.

CAUSE

The theft deterrent relay is a component of the ignition switch crank circuit on vehicles built with and without remote keyless entry/Saturn security system (RKE/SSS) content. When the relay is grounded, and the ignition switch is turned to the crank mode, the relay is energized and the contacts close. Battery voltage is then supplied to the starter solenoid. If the vehicle has been subjected to cold ambient temperatures of 0° C (32° F) or lower, the coil may not energize, causing the contacts to stay open. If the contacts stay open, a no click, no crank condition will result, causing a no start condition.

CORRECTION

If the condition is verified as cold temperature related, refer to the following procedure and inspect the theft deterrent relay date code located on the side of the relay body, opposite the electrical diagram on the relay. If the date code is 6119 or lower, replace the theft deterrent relay with a theft deterrent relay manufactured with a date code of 6120 or higher.

PROCEDURE

1. Remove theft deterrent relay. (Refer to "Starter Relay" under "Starter Service Procedures" in the "Starting/Charging" section of the "1997 Electrical Service Manual.")
   NOTE: The theft deterrent relay is called the starter relay in the Saturn service manual.
2. Inspect date code on the theft deterrent relay. If it is 61l9 or lower, replace the theft deterrent relay. If the date code is 6120 or later, refer to appropriate No Start diagnosis procedures in the appropriate service manual.
3. Install theft deterrent relay. (Refer to "Starter Relay" under "Starter Service Procedures" in the "Starting/Charging" section of the "1997 Electrical Service Manual.")
