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.

Ignition/Vehicle - Off
Disconnect the electrical connector:S47D Seat Memory Switch - Driver
Ignition - On / Vehicle - In Service Mode
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 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
Ignition/Vehicle - Off
Disconnect the electrical connector:X6@K40D Seat Memory Control Module - Driver
Ignition - On / Vehicle - In Service Mode
Test for less than 1 V between the test points:
- Signal circuit terminal 5@Component harness & Ground
- Signal circuit terminal 6@Component harness & Ground
- If 1 V or greater
  Repair the short to voltage on the circuit.
- Go to next step: If less than 1 V
Test or replace the component:S47D Seat Memory Switch - Driver
