Circuit/System Testing

2022 Chevrolet Trax LT, AWDSECTION Circuit/System Testing
  1. Ignition/Vehicle & All vehicle systems - Off
  2. Disconnect the electrical connector: S155 Lane Departure Warning Switch
  3. Verify a test lamp turns On between the test points: Ground circuit terminal 3 & B+
    • If the test lamp does not turn On 
    1. Test for less than 2 ohms between the test points: Ground circuit terminal 3 @ Component harness & Ground terminal
      • 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 the test lamp turns On 
  4. Ignition - On/Vehicle - In Service Mode
  5. Test for greater than 11 V between the test points: Signal circuit terminal 5 & Ground
    • If 11 V or less 
    1. Ignition/Vehicle - Off
    2. Disconnect the electrical connector: B174W Frontview Camera - Windshield
    3. Test for infinite resistance between the test points: Signal circuit terminal 5 @ Component harness & Ground
      • If less than infinite resistance - Repair the short to ground on the circuit.
      • Go to next step: If infinite resistance
    4. Test for less than 2 ohms between the test points: Signal circuit terminal 5 @ Component harness & Signal circuit terminal 10 @ Control module harness
      • If 2 ohms or greater - Repair the open/high resistance in the circuit.
      • If less than 2 ohms - Replace the component: B174W Frontview Camera - Windshield
    • If greater than 11 V 
  6. Ignition/Vehicle & All vehicle systems - Off
  7. Connect the electrical connector: S155 Lane Departure Warning Switch
  8. Ignition - On/Vehicle - In Service Mode
  9. Verify the scan tool parameter: Lane Departure Warning Switch Status = Inactive
    • If not the specified state 

      Test or replace the component: S155 Lane Departure Warning Switch

    • Go to next step: If the specified state 
  10. Operate the component: Lane Departure Warning Switch - Press and hold the switch

    Verify the scan tool parameter: Lane Departure Warning Switch Status = Active

    • If not the specified state 
    1. Ignition/Vehicle & All vehicle systems - Off
    2. Disconnect the electrical connector: B174W Frontview Camera - Windshield & S155 Lane Departure Warning Switch
    3. Ignition - On/Vehicle - In Service Mode
    4. Test for less than 1 V between the test points: Signal circuit terminal 5 @ Component harness & Ground
      • If 1 V or greater - Repair the short to voltage on the circuit.
      • Go to next step: If 1 V or less
    5. Test or replace the component: S155 Lane Departure Warning Switch
    • Go to next step: If the specified state 
  11. All OK.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • • You smell fuel, burning insulation, or see smoke.
  • • Brakes feel soft, pull hard to one side, or make grinding noises.
  • • The engine overheats, stalls repeatedly, or misfires under load.
  • • You are missing required tools, torque specs, or safe lifting equipment.
  • • You are not confident in the next step or safety outcome.
