Circuit/System Testing
WARNING: This page is about a different variant/trim than selected.
- Ignition/Vehicle & All vehicle systems - Off
- Disconnect the electrical connector: S3 Transmission Shift Lever
- Test for less than 10 ohms between the test points: Ground circuit terminal 2 (harness side) & 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 @ Component harness & 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: Driver Shift Control Mode Switch @ K9 Body Control Module = Inactive
- If not the specified state
- Ignition/Vehicle - Off
- Disconnect the electrical connector: X2 @ K9 Body Control Module
- Test for infinite resistance between the test points: Signal circuit terminal 11 @ Control module harness & 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 3 (harness side) & Ground
- Verify the scan tool parameter: Driver Shift Control Mode Switch @ K9 Body Control Module = Invalid
- If not the specified state
- Ignition/Vehicle - Off & Remove - Jumper wire(s)
- Disconnect the electrical connector: X2 @ K9 Body Control Module
- Ignition - On/Vehicle - In Service Mode
- Test for less than 1 V between the test points: Signal circuit terminal 11 @ Control module harness & 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 3 @ Component harness & Signal circuit terminal 11 @ Control module harness
- 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: S2 Transmission Manual Shift Switch
NOTE:
Circuit/System Verification must be performed before proceeding with Circuit/System Testing.
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.
