DEFINITION: One of more of the memory recall functions are inoperative.
1 Did you perform the Diagnostic System Check - Vehicle? - Go to Step 2  Go to Diagnostic System Check - Vehicle in Vehicle DTC Information
2 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. 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 Ω Go to Step 4  Go to Step 6

  1. 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 driver seat module (DSM) harness connector. Refer to Circuit Testing in Wiring Systems.
  2. Press the memory 2 switch.
Is the resistance less than the specified value only while the switch is pressed?		 0.5 Ω Go to Step 5  Go to Step 6 
5
  1. 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 DSM harness connector. Refer to Circuit Testing in Wiring Systems.
  2. Press the SET switch.
Is the resistance less than the specified value only while the switch is pressed?		 0.5 Ω Go to Step 8  Go to Step 6 
6 Test the affected memory switch signal circuit for the following conditions:
  • Short to ground
  • Short to voltage
  • Open

Refer to Circuit Testing and Wiring Repairs in Wiring Systems.
Did you find and correct the condition?		 - Go to Step 11  Go to Step 7 
7 Inspect for poor connections at the memory switch connector. Refer to Testing for Intermittent Conditions and Poor Connections andConnector Repairs in Wiring Systems.
Did you find and correct the condition?		 - Go to Step 11  Go to Step 9 
8 Inspect for poor connections at the driver seat module. Refer to Testing for Intermittent Conditions and Poor Connections andConnector Repairs in Wiring Systems.
Did you find and correct the condition?		 - Go to Step 11  Go to Step 10 
9 Replace the memory switch. Refer to Seat Switch Replacement - Power .
Did you complete the replacement?		 - Go to Step 11  -
10 Replace the DSM. Refer to Control Module References in Computer/Integrating Systems for replacement, setup, and programming.
Did you complete the replacement?		 - Go to Step 11  -
11 Operate the memory seat system to verify the repair.
Did you correct the condition?		 - System OK Go to Step 2
