WARNING: This page is about a different car, the 2015 Chevrolet Trax and 2015 Buick Encore. However, it is still accessible from the selected car via links, so may be relevant.
  1. Ignition OFF, disconnect the harness connector at the S64D Seat Adjuster Switch - Driver, Ignition ON.
  2. Verify that all scan tool driver seat switch parameters listed below are Inactive:
    • Driver Seat Cushion Front Vertical Switch
    • Driver Seat Cushion Rear Vertical Switch
    • Driver Seat Horizontal Switch
    • If not Inactive 
    1. Ignition OFF, disconnect the harness connector at the K40 Seat Memory Control Module.
    2. Test for infinite resistance between the appropriate signal circuit terminal listed below and ground:
      • Front vertical up switch terminal G
      • Front vertical down switch terminal E
      • Rear vertical up switch terminal H
      • Rear vertical down switch terminal A
      • Horizontal forward switch terminal F
      • Horizontal rearward switch terminal C
      • If less than infinite resistance, repair the short to ground on the circuit.
      • If infinite resistance, replace the K40 Seat Memory Control Module.
    • If Inactive 
  3. Install a 3 A fused jumper wire between the appropriate signal circuit terminal listed below and the ground circuit terminal D.
    • Front vertical up switch terminal G
    • Front vertical down switch terminal E
    • Rear vertical up switch terminal H
    • Rear vertical down switch terminal A
    • Horizontal forward switch terminal F
    • Horizontal rearward switch terminal C
  4. Verify the scan tool seat switch parameter is Forward/Rearward or UP/Down.
    • If not Forward/Rearward or UP/Down 
    1. Ignition OFF, disconnect the harness connector at the K40 Seat Memory Control Module, ignition ON.
    2. Test for less than 1 V between the signal circuit terminal and ground.
      • If 1 V or greater, repair the short to voltage on the circuit.
      • If less than 1 V
    3. Ignition OFF.
    4. Test for less than 2 Ω in the signal circuit end to end.
      • If 2 Ω or greater, repair the open/high resistance in the circuit.
      • If less than 2 Ω, replace the K40 Seat Memory Control Module.
    • If Forward/Rearward or UP/Down 
  5. Test or replace the S64D Seat Adjuster Switch - Driver.
