Go to Step 2

Go to Diagnostic System Check - Vehicle

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

Does the system operate normally?

--

Go to Testing for Intermittent Conditions and Poor Connections

Go to Step 3

1. Install a scan tool.
2. Observe the Memory Switch parameter in the Driver Door Module Inputs Data List.
3. Press the memory 1 switch.

Does the scan tool display the memory 1 switch as Active only while the switch is pressed?

--

Go to Step 4

Go to Step 6

1. Observe the Memory Switch parameter in the Driver Door Module Inputs Data List.
2. Press the memory 2 switch.

Does the scan tool display the memory 2 switch as Active only while the switch is pressed?

--

Go to Step 5

Go to Step 7

1. Observe the Memory Switch parameter in the Driver Door Module Inputs Data List.
2. Press the EXIT switch.

Does the scan tool display the EXIT switch as Active only while the switch is pressed?

Go to Step 12

Go to Step 8

1. Disconnect the memory switch connector from the driver door module.
2. Using a DMM test the resistance through the memory switch from the switch supply voltage circuit terminal to the memory 1 switch signal circuit terminal in the pigtail connector. Refer to Circuit Testing and to Wiring Repairs .
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 13

Go to Step 11

1. Disconnect the memory switch connector from the driver door module.
2. Using a DMM test the resistance through the memory switch from the switch supply voltage circuit terminal to the memory 2 switch signal circuit terminal in the pigtail connector. Refer to Circuit Testing and to Wiring Repairs.
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 9

Go to Step 11

1. Using a DMM test the resistance through the memory switch from the switch supply voltage circuit terminal to the memory 2 switch signal circuit terminal in the pigtail connector. Refer to Circuit Testing and to Wiring Repairs.
2. Press the EXIT switch.

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

0.5 ohms

Go to Step 10

Go to Step 11

Test the memory switch signal circuits in the switch harness for a short to ground or voltage. Refer to Circuit Testing.

Are either of the switch signal circuits shorted to ground or voltage?
