Go to Step 2

Go to Outside Mirrors System Check

1. Turn the ignition switch to the OFF position.
2. Ground the memory seat diagnostic connector:

•	The connector may be taped into the body harness.

•	The module beeps once in order to acknowledge entrance into the mode 1 diagnostics.

•	If the module does not enter the diagnostic mode, refer to Memory Seats System Check in Seats.

•	Refer to Memory Seat Circuit Description in Seats for a detailed explanation of the memory seat/mirror module diagnostic modes.

3. Operate the DRIVER-1 and the DRIVER-2 recall buttons and the memory set button on the left seat/lock switch. (The module beeps once for each switch input received.)
4. Any time a switch is operated and the module does not beep, the module did not receive the input from that switch.

Are there any switch operations where the memory seat/mirror does not beep?

Go to Step 6

Go to Step 3

1. Remove the ground from the memory seat diagnostic connector, then ground the connector again within 5 seconds:

•	The module beeps twice in order to acknowledge entrance into the mode 2 diagnostics.

•	Refer to Memory Seat Circuit Description in Seats for a detailed explanation of the memory seat/mirror module diagnostic modes.

2. Operate the seat switch and the power mirror switch in all directions. (The module beeps once for each open or short circuit to a position sensor or any position sensor discontinuity.)
3. Any time a switch is operated and the module beeps, the module senses a problem with the position sensor.

Are there any switch operations where the memory seat/mirror module beeps?

Go to Step 10

Go to Step 9

1. Disconnect the memory seat/mirror module connector C1.
2. Test the following terminals with a digital multimeter (DMM)

•	D8 - Memory set switch

•	D5 - Memory select switch position 1

•	C9 - Memory select switch position 2

Does the voltage measure within the specified range for each terminal?

10-15 V

Go to Step 10

Go to Step 7

Test the following circuits for an open:

Are all of the circuits OK?
