Circuit/System Testing

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

Ignition OFF, disconnect the harness connector at the S47D Seat Memory Switch - Driver.
Test for less than 30 Ω between the low reference circuit terminal 1 and ground.
- If 30 Ω or greater
1. Ignition OFF, disconnect the X6 harness connector at the K40D Seat Memory Control Module - Driver.
2. Test for less than 2 Ω in the low reference circuit end to end
  - If 2 Ω or greater, repair the open/high resistance in the circuit.
  - If less than 2 Ω, replace the K40D Seat Memory Control Module - Driver.
- Go to next step: If less than 30 Ω
Ignition ON, press a power seat switch in order to wake up the K40D Seat Memory Control Module - Driver.
Test for 9 V or greater between each signal circuit terminal listed below and ground:
- Memory set switch signal terminal 5
- Memory switch signal terminal 6
- If less than 9 V
1. Ignition OFF, disconnect the X6 harness connector at the K40D Seat Memory Control Module - Driver.
2. Test for infinite resistance between the signal circuit and ground.
  - If less than infinite resistance, repair the short to ground on the circuit.
  - Go to next step: If infinite resistance
3. 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 K40D Seat Memory Control Module - Driver.
- Go to next step: If 9 V or greater
Ignition OFF, disconnect the X6 harness connector at the K40D Seat Memory Control Module - Driver, ignition ON.
Test for less than 1 V between each signal circuit terminal listed below and ground:
- Memory set switch signal terminal 5
- Memory switch signal terminal 6
- 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 S47D Seat Memory Switch - Driver.
