Go to Step 2

Go to Diagnostic System Check - Vehicle in Vehicle DTC Information

From the Driver Door Memory Switch 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 in Wiring Systems

Go to Step 3

1. Install a scan tool.
2. Observe the Memory Switch parameter in the driver door module (DDM) 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 DDM 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 DDM 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 DDM.
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 switch harness connector. Refer to Circuit Testing and to Wiring Repairs 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 13

Go to Step 11

1. Disconnect the memory switch connector from the DDM.
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 switch harness connector. Refer to Circuit Testing and to Wiring Repairs 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 13

Go to Step 11

1. Disconnect the memory switch connector from the DDM.
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 switch harness connector. Refer to Circuit Testing and to Wiring Repairs in Wiring Systems.
3. Press the EXIT switch.

Is the resistance less than the specified value?

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 switch harness connector. Refer to Circuit Testing and to Wiring Repairs in Wiring Systems.
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 in Wiring Systems.

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

Go to Step 14

Go to Step 13

Inspect for poor connections at the memory switch connector. Refer to Testing for Intermittent Conditions and Poor Connections and to Connector Repairs in Wiring Systems.

Did you find and correct the condition?

--

Go to Step 17

Go to Step 14

Inspect for poor connections at the driver seat module (DSM) connectors. Refer to Testing for Intermittent Conditions and Poor Connections and to Connector Repairs in Wiring Systems.

Did you find and correct the condition?

--

Go to Step 17

Go to Step 15

Inspect for poor connections at the DDM connector. Refer to Testing for Intermittent Conditions and Poor Connections and to Connector Repairs in Wiring Systems.

Did you find and correct the condition?

--

Go to Step 17

Go to Step 16

Replace the memory switch. Refer to Front Seat Heater Switch Replacement .
