Did you perform the Memory Mirror System Check?

--

Go to Step 2

Go to Outside Mirrors System Check

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

•	The connector may be taped up into the body harness.

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

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

3. Operate the power mirror switch in all directions. (The module beeps once for each received switch input.)
4. Any time a switch is operated and the module does not beep, the module did not receive an input from that switch.

Were there any switch operations where the memory seat/mirror module beeped?

Go to Step 3

1. Disconnect the power mirror switch connector.
2. Measure the voltage to ground from the power mirror switch connector terminal E.

Does the voltage measure within the specified range?

10-15 V

Go to Step 4

Go to Step 7

Measure the voltage between the following power mirror switch connector terminals:

Does the voltage measure within the specified range?

10-15 V

Go to Step 5

Go to Step 8

Test the following circuits for an open:

Is CKT 1516 or CKT 1831 OK?
