DEFINITION: One or 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, 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 
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 
4
  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 
5
  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 
6
  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 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 13  Go to Step 11 
7
  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 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 Ω 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 1 switch signal circuit terminal in the pigtail 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 Ω Go to Step 9  Go to Step 11 
9
  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 in Wiring Systems.
  2. Press the EXIT switch.
Is the resistance less than the specified value only while the switch is pressed?		 0.5 Ω Go to Step 10  Go to Step 11 
10 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 
11 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 
12 Inspect for poor connections at the driver seat module 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 
13 Inspect for poor connections at the driver door module 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 
 
14		 Replace the memory switch. Refer to Heated Seat Switch Replacement - Front .
Is the repair complete?		 - Go to Step 17  -
15 Replace the driver seat module. Refer to Control Module References in Computer/Integrating Systems for replacement, setup, and programming.
Is the repair complete?		 - Go to Step 17  -
16 Replace the driver door module. Refer to Control Module References in Computer/Integrating Systems for replacement, setup, and programming.
Is the repair complete?		 - Go to Step 17  -
17 Operate the memory seat system to verify the repair.
Did you correct the condition?		 - System OK Go to Step 3

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • • You smell fuel, burning insulation, or see smoke.
  • • Brakes feel soft, pull hard to one side, or make grinding noises.
  • • The engine overheats, stalls repeatedly, or misfires under load.
  • • You are missing required tools, torque specs, or safe lifting equipment.
  • • You are not confident in the next step or safety outcome.
