Troubleshooting Hints

PERFORM BEFORE BEGINNING SYSTEM DIAGNOSIS:

NOTE:
^ The Multi-Function Alarm Module will "go to sleep" 3 or 20 minutes after "key off" depending if the vehicle has traveled over 15 miles. Until the Multi-Function Alarm Module "goes to sleep," it will draw 60-80ma. Once the Multi-Function Alarm Module "goes to sleep," the amperage draw will drop to 3-15ma.

^ If the vehicle is left for 24 or more days without the ignition being put in the "RUN" position, the Keyless Entry and Illuminated Entry Features will be disabled to decrease parasitic battery drain. Putting the ignition switch in "RUN" will restore these features.
1. Check that ground G302 is clean and tight.
2. Check the RDO Fuse by observing the operation of the Radio.
3. Check the PWR ACC Fuse by operating the Power Door Locks.
4. Always check terminal contact before replacing any component.
5. If a second transmitter is available, try it. If it works, change the batteries in the first transmitter and try it again. If still not operational, replace the transmitter.
6. Check Transmitter battery terminals. They should be clean and make good contact with the battery.
7. If in doubt as to the condition of the Transmitter batteries, replace them with new ones. Checking the battery voltage with a DVOM may give false results.
8. If a motor's internal circuit breaker trips, it will not reset until voltage is removed from the motor.
^ Check for broken (or partially broken) wire inside of the insulation which could cause system failure but prove "Good" in continuity/voltage check.
^ Check for proper installation of aftermarket electronic equipment which may affect the integrity of other systems.
