DEFINITION: One of more of the memory recall functions are inoperative.

Did you perform the Power Seat Diagnostic System Check?

--

Go to Step 2

Go to Diagnostic System Check - Power Seat Systems

Attempt to set and recall memory 1, and memory 2, seat position settings.

Does the system operate normally?

--

Go to Testing for Intermittent Conditions and Poor Connections in Wiring Systems

Go to Step 3

1. Install a scan tool.
2. Observe the memory switch parameters in the driver seat module data list.
3. Press the memory 1 switch.

Does the scan tool indicate the memory 1 switch is active only while the switch is pressed?

--

Go to Step 4

Go to Step 6

Press the memory 2 switch.

Does the scan tool indicate the memory 2 switch is active only while the switch is pressed?

--

Go to Step 5

Go to Step 7

Press the set switch.

Does the scan tool indicate the set switch is active only while the switch is pressed?

Go to Step 11

Go to Step 8

1. Disconnect the driver seat module connector C2.
2. Using a DMM test the resistance through the memory switch from the voltage supply circuit terminal to the memory 1 switch signal circuit terminal in the harness connector. Refer to Circuit Testing in Wiring Systems.
3. Press the memory 1 switch.

Is the resistance less than the specified value only while the switch is pressed?

0.5 ohms

Go to Step 11

Go to Step 10

1. Disconnect the driver seat module connector C2.
2. Using a DMM test the resistance through the memory switch from the voltage supply circuit terminal to the memory 2 switch signal circuit terminal in the harness connector. Refer to Circuit Testing in Wiring Systems.
3. Press the memory 2 switch.

Is the resistance less than the specified value only while the switch is pressed?

0.5 ohms

Go to Step 11

Go to Step 10

1. Disconnect the driver seat module connector C2.
2. Using a DMM test the resistance through the memory switch from the voltage supply circuit terminal to the memory set switch signal circuit terminal in the harness connector. Refer to Circuit Testing in Wiring Systems.
3. Press the set switch.

Is the resistance less than the specified value only while the switch is pressed?

0.5 ohms

Go to Step 9

Go to Step 10

Test the affected memory switch signal circuit for the following conditions:

1. Short to ground
2. Short to voltage
3. Open

Refer to Circuit Testing and to Wiring Repairs in Wiring Systems.
