TESTING

Module Self Test Programmable Memory Seat The memory seat module has a built-in self-test feature that greatly enhances its serviceability. To place the module into the self-test mode, press the white button located on the top of the module.

NOTE: If the seat is stuck in the most rearward and down position, it may be necessary to remove the seat to self test the module.

There are two versions of the self-test: in-vehicle and off-vehicle.


In-Vehicle

1. Press white button located on module.

2. If system finds no problems it will flash a light emitting diode (LED) (located next to white button on module) four to six times.

3. If system does find a problem, LED will either not flash at all, or it will flash less than four, or more than six times. If module passes test, check other components in system. If module fails in-vehicle test, perform an off-vehicle test.

NOTE: If module fails in-vehicle self test, it does not confirm that module is damaged. Also note that passing in-vehicle self test does not guarantee that system is operating properly In-vehicle self test is meant to be a service aid, not a total system diagnostic lest.

Off-Vehicle

1. Disconnect all connectors leading to module.

2. Apply 12 volts to terminals 54, and 517. Connect terminals 57 and 57A in 12-way gray connector to ground.

3. Push white self-test connector located on module.

4. If system finds no problems it will flash a light emitting diode (LED) (located next to white button on module) four to six times.

5. If system does find a problem, LED will either not flash at all, or it will flash less than four or more than six limes.

If module passes test, check other components in system. If module fails off-vehicle test, replace module.
