Circuit/System Testing

WARNING: This page is about a different car, the 2019 Chevrolet Malibu. However, it is still accessible from the selected car via links, so may be relevant.
    NOTE:

    It may take up to 2 min for all vehicle systems to power down before an accurate ground or low reference circuit continuity test can be performed.

  1. Ignition/Vehicle & All vehicle systems - Off
  2. Disconnect the electrical connector:S47D Seat Memory Switch - Driver
  3. Test for less than 30 ohms between the test points:Low Reference circuit terminal 1 & Ground
    • If 30 ohms or greater 
    1. Disconnect the electrical connector:X6@K40D Seat Memory Control Module - Driver
    2. Test for less than 2 ohms between the test points:Low Reference circuit terminal 1@Component harness & Terminal 11 X6@Control module harness
      • If 2 ohms or greater - Repair the open/high resistance in the circuit.
      • If less than 2 ohms - Replace the component:K40D Seat Memory Control Module - Driver
    • Go to next step: If less than 30 ohms 
  4. Ignition - On / Vehicle - In Service Mode
  5. Operate the component:S64D Seat Adjuster Switch - Driver = Pressed

    Test for greater than 9 V between the test points:

    • Signal circuit terminal 5@Component harness & Ground
    • Signal circuit terminal 6@Component harness & Ground
    • If less than 9 V 
    1. Ignition/Vehicle - Off
    2. Disconnect the electrical connector:X6@K40D Seat Memory Control Module - Driver
    3. Test for infinite resistance between the test points:
      • Signal circuit terminal 5@Component harness & Ground
      • Signal circuit terminal 6@Component harness & Ground
      • If less than infinite resistance - Repair the short to ground on the circuit.
      • Go to next step: If less than infinite resistance
    4. Test for less than 2 ohms between the test points:Signal circuit terminal@Component harness & The other end of the circuit@Control module harnessX6
      • Signal circuit terminal 5@Component harness & Terminal 15 X6@Control module harness
      • Signal circuit terminal 6@Component harness & Terminal 12 X6@Control module harness
      • If 2 ohms or greater - Repair the open/high resistance in the circuit.
      • If less than 2 ohms - Replace the component:K40D Seat Memory Control Module - Driver
    • Go to next step: If 9 V or greater 
  6. Ignition/Vehicle - Off
  7. Disconnect the electrical connector:X6@K40D Seat Memory Control Module - Driver
  8. Ignition - On / Vehicle - In Service Mode
  9. Test for less than 1 V between the test points:
    • Memory Seat Switch Set SignalTerminal 5 & Ground
    • Memory Seat Switch Signal 1Terminal 6 & Ground
    • If 1 V or greater 

      Repair the short to voltage on the circuit.

    • Go to next step: If less than 1 V 
  10. Test or replace the component:S47D Seat Memory Switch - Driver
