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 is 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 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.

2.

3.
Measure the voltage between HomeLink control unit 8P 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. A21 (10 A) fuse in the under-hood fuse/relay box.
?
Faulty 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 4.
4.
Make sure the genuine HomeLink remote transmitter (test remote) has fresh batteries.

5.
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.
6.
Point the test remote transmitter (A) straight up exactly 101.6 mm (4.0 in) 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 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, go online to www.homelink.com.
If the red indicator does not blink, the HomeLink unit is faulty; replace it.
