Circuit/System Testing

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

  1. Ignition/Vehicle & All vehicle systems - Off
  2. Disconnect the electrical connector: A9A Outside Rearview Mirror - DriverorA9B Outside Rearview Mirror - Passenger
  3. Test for less than 10 ohms between the test points: Ground circuit terminal 5 & Ground
    • If 10 ohms or greater 
    1. Disconnect the appropriate ground connection: G305
    2. Test for less than 2 ohms between the test points: Ground circuit terminal 5 @ Component harness & Terminal G305
      • 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 
    4. NOTE:

    Make sure to use a high impedance test lamp like special tool EL-35616-210.

  4. Connect a test lamp between the test points: Control circuit terminal 15 & Ground
  5. Perform the appropriate scan tool control function: Side Object Detection Alert LEDs - Cycle On and Off
    • If the test lamp is always Off 
    1. Ignition/Vehicle - Off & Remove - Jumper wire(s)
    2. Disconnect the electrical connector: B218L Side Object Sensor Module - Left or B218R Side Object Sensor Module - Right
    3. Test for less than 2 ohms between the test points: Control circuit terminal 15 @ Component harness & Terminal 4 @ Control module harness
      • If 2 ohms or greater - Repair the open/high resistance in the circuit.
      • If less than 2 ohms - Replace the component: B218 Side Object Sensor Module
    • If the test lamp is always On 
    1. Ignition/Vehicle - Off & Remove - Jumper wire(s)
    2. Disconnect the electrical connector: B218L Side Object Sensor Module - Left or B218R Side Object Sensor Module - Right
    3. Ignition - On / Vehicle - In Service Mode
    4. Test for less than 1 V between the test points: Control circuit terminal 15 @ Component harness & Ground
      • If 1 V or greater - Repair the short to voltage on the circuit.
      • If less than 1 V - Replace the component: B218 Side Object Sensor Module
    • Go to next step: If the test lamp turns On and Off 
  6. Test or replace the component: E17 Outside Rearview Mirror Glass
