Circuit/System Testing
- Ignition/Vehicle & All vehicle systems - Off
- Disconnect the electrical connector: S48E Multifunction Switch - Center Console
- Test for less than 10 ohms between the test points: Ground circuit terminal 2 & Ground
- If 10 ohms or greater
- Disconnect the ground connection: G201
- Test for less than 2 ohms between the test points: Ground circuit terminal 2 @ S48E Multifunction Switch - Center Console & Terminal G201
- If 2 ohms or greater - Repair the open/high resistance in the circuit.
- If less than 2 ohms - Repair the open/high resistance in the ground connection.
- Go to next step: If less than 10 ohms
- Ignition - On/Vehicle - In Service Mode
- Verify the scan tool parameter: Traction Control Switch @ K9 Body Control Module = Inactive
- If not the specified state
- Ignition/Vehicle - Off
- Disconnect the electrical connector: X2 Harness Connector @ K9 Body Control Module
- Test for infinite resistance between the test points: Signal circuit terminal 14 @ X2 Harness Connector & Ground
- If less than infinite resistance - Repair the short to ground on the circuit.
- If infinite resistance - Replace the component: K9 Body Control Module
- Go to next step: If the specified state
- Connect a 3 A fused jumper wire between the test points: Signal circuit terminal 7 & Ground circuit terminal 2
- Verify the scan tool parameter: Traction Control Switch @ K9 Body Control Module = Active
- If not the specified state
- Ignition/Vehicle - Off & Remove - Jumper wire(s)
- Disconnect the electrical connector: X2 Harness Connector @ K9 Body Control Module
- Ignition - On/Vehicle - In Service Mode
- Test for less than 1 V between the test points: Signal circuit terminal 14 @ X2 Harness Connector & Ground
- If 1 V or greater - Repair the short to voltage on the circuit.
- Go to next step: If less than 1 V
- Ignition/Vehicle - Off
- Test for less than 2 ohms between the test points: Signal circuit terminal 7 @ S48E Multifunction Switch - Center Console & Terminal 14 @ X2 Harness Connector
- If 2 ohms or greater - Repair the open/high resistance in the circuit.
- If less than 2 ohms - Replace the component: K9 Body Control Module
- Go to next step: If the specified state
- Test or replace the component: S48E Multifunction Switch - Center Console
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.
NOTE:
Circuit/System Verification must be performed before proceeding with Circuit/System Testing.
