Circuit/System Testing

WARNING: This page is about a different variant/trim than selected.

Ignition OFF, disconnect the harness connector from the S3 transmission shift lever.
Test for less than 10 Ω between the S3 transmission shift lever harness connector terminal 2 and ground.
- If 10 Ω or greater
  Test for less than 2 Ω in the ground circuit end to end.
- If 2 Ω or greater, repair the open/high resistance in the circuit.
- If less than 2 Ω, repair the open/high resistance in the ground connection.
- If less than 10 Ω
Ignition ON.
Test for 11 V or greater at the S3 transmission shift lever harness connector between signal circuit terminal 3 and ground.
- If less than 11 V
1. Ignition OFF, remove the connector at the K9 body control module.
2. Test for infinite resistance between the S3 transmission shift lever harness connector signal circuit terminal 3 and ground.
  - If less than infinite resistance, repair the short to ground in the circuit.
  - 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 K9 body control module.
- If 11 V or greater
Ignition OFF.
Test for 5.8-6.4 kΩ between the S3 transmission shift lever connector terminal 3 and terminal 2.
- If not between 5.8-6.4 kΩ
  Replace the S3 transmission shift lever.
- If between 5.8-6.4 kΩ
Test for 1.8-2.2 kΩ between the S3 shift lever connector terminal 3 and terminal 2 with the tap down button depressed.
- If not between 1.8-2.2 kΩ
  Replace the S3 transmission shift lever.
- If between 1.8-2.2 kΩ
Test for 580-680 Ω between the S3 shift lever connector terminal 3 and terminal 2 with the tap up button depressed.
- If not between 580-680 Ω
  Replace the S3 transmission shift lever.
- If between 580-680 Ω
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 K9 body control module.
