Garage Door Opener Transmitter: Testing and Inspection

HomeLink Remote Control System Test

NOTE:

- Explain to the customer that garage door remote transmitters come in two types: fixed code and rolling code. Each type has its own programming method, and each method covered in the owner's manual. If the customer has concerns about the HomeLink unit, have the customer contact the HomeLink assistance desk at 800-355-3515.
- If HomeLink will not open the customer's garage, do the following procedures.

1. Press any of the buttons on the HomeLink unit.

- If the red indicator comes on, go to step 4.
- If the red indicator does not come on, go to step 2.

2. Remove the front individual map light (A) Service and Repair, and disconnect the 10P connector (B).






3. Measure the voltage between HomeLink unit 10P connector (A) terminals No. 6 (+) and No. 5 (-). There should be battery voltage.

- If the voltage is not as specified, check for these problems:
- A blown No. 6 (10 A) fuse in the under-dash fuse/relay box
- A faulty under-dash fuse/relay box
- An open or high resistance in the wire
- Poor ground (G401) or an open in the ground wire
- If there is battery voltage, go to step 4.





4. Make sure the HomeLink compatible remote transmitter (test remote) has fresh batteries.

5. Clear any previously learned codes by pressing and holding the two outside buttons (A) on the HomeLink unit (B). When the red indicator (C) on the unit starts blinking, about 20 seconds then release the buttons.






6. Point the test remote transmitter (A) straight up exactly 4.0 in (101.6 mm) away from the HomeLink unit (B).





7. Press and hold the test transmitter button and one of the HomeLink unit buttons (C) at the same time.

8. Wait for about 20 seconds while watching the red indicator (D) on the HomeLink unit.

- If the red indicator starts out blinking slowly and then blinks faster, the unit is OK. Release the buttons, then clear the learned code (see step 1).
- If the red indicator does not blink, HomeLink unit is faulty; replace the ambient light Service and Repair.
