HOMELINK Remote Control System Test (Without Panoramic Glass Roof) (2016 2017 2018)

NOTE:

Explain to the client that garage door remote transmitters come in two types: Fixed code and rolling code. Each type has its own programming method, and each method is covered in the Owner's Manual. If the client has concerns about the HomeLink unit, have the client contact the HomeLink assistance desk at 800-355-3515.
If HomeLink will not open the client'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.

If the switch is OK, go to step 3.
If the switch is faulty, replace the HomeLink unit. - Go to: HomeLink Unit - Removal and Installation (Without Panoramic Glass Roof) .

3. Disconnect the HomeLink unit 7P connector - Go to: HomeLink Unit - Removal and Installation (Without Panoramic Glass Roof) .

4. Measure the voltage between HomeLink control unit 7P connector terminals No. 1 (+) and No. 4 (-). There should be battery voltage.

If the voltage is not as specified, check for these problems:
- Blown No. A26 (10 A) fuse in the under-hood fuse/relay box.
- Faulty driver's under-dash fuse/relay box.
- An open or high resistance in the wire.
- Poor ground (G501).
If the voltage is as specified, go to step 5.

5. Make sure the customer's remote transmitter (or a test remote) has fresh batteries.

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

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

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

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). For more information, contact the HomeLink assistance desk or go online to www.homelink.com.
