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 customer's garage, do the following procedures.
Before testing, make sure the fuses associated with the system is OK.

With Panoramic Glass Roof

1.
Press any of the buttons on the HomeLink® unit.
If the red indicator comes on, go to step 6.
If the red indicator does not come on, go to step 2.

2.
If the switch is OK, go to step 3.
If the switch is faulty, replace the roof console module.

3.
Disconnect the HomeLink® unit 12P connector.

4.
Check for continuity between the HomeLink® unit and the HomeLink® switch (built into the roof console module).
If there is continuity, go to step 5.
If there is no continuity, repair an open or high resistance in the wire.

5.
Measure the voltage between HomeLink® unit 12P connector terminals No. 6 (?) and No. 3 (?). There should be battery voltage.
If the voltage is not as specified, check for these problems:
?
An open or high resistance in the wire.
?
Poor ground (G401).
If the voltage is as specified, go to step 6.

6.
Make sure the customer's remote transmitter (or a test remote) has fresh batteries.

7.
Clear any previously learned codes by pressing and holding the two outside buttons (A) on the roof console module (B) until the red indicator (C) on the unit starts blinking (about 20 seconds), then release the buttons.
8.
Point the test remote transmitter (A) straight up exactly 101.6 mm (4.0 in) away from the HomeLink® unit (B).

9.
Press and hold the test transmitter button and one of the HomeLink® switch (C) at the same time.
10.
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 at 800-355-3515 or go online to www.homelink.com.
If the red indicator does not blink, the HomeLink® unit is faulty; replace it.

2.
Disconnect the HomeLink® unit 5P connector.

3.
Measure the voltage between HomeLink® unit 5P connector terminals No. 1 (?) and No. 4 (?). There should be battery voltage.
If the voltage is not as specified, check for these problems:
?
An open or high resistance in the wire.
