Circuit/System Testing

WARNING: This page is about a different car, the 2010 Pontiac G5 and 2010 Chevrolet Cobalt. However, it is still accessible from the selected car via links, so may be relevant.
  1. Ignition OFF, disconnect the harness connector at the yaw/lateral accelerometer sensor.
  2. Ignition OFF for 60 seconds, test for less than 5 Ω between the low reference circuit terminal 5 and ground.
    • If greater than the specified range, test the low reference circuit for an open/high resistance.
  3. Ignition ON, test for B+ between the ignition voltage circuit terminal 3 and ground.
    • If not within the specified range, test the ignition voltage circuit for a short to ground or open/high resistance.
  4. Ignition OFF, disconnect the harness connector at the EBCM.
  5. Ignition ON, test for less than 1 V between serial data signal terminals listed below and ground:
    • CAN Bus High serial data signal circuit terminal 18
    • CAN Bus Low serial data signal circuit terminal 19
    • If greater than the specified value, test the serial data signal circuit for a short to voltage.
  6. Ignition OFF, test for infinite resistance between serial data signal terminas listed below and ground:
    • CAN Bus High serial data signal circuit terminal 18
    • CAN Bus Low serial data signal circuit terminal 19
    • If not the specified value, test the serial data signal circuit for a short to ground.
  7. Test for less than 2 Ω between the serial data signal terminals listed below:
    • CAN Bus High serial data signal circuit terminal 18 at the EBCM harness connector and terminal 2 at the yaw/lateral accelerometer sensor harness connector.
    • CAN Bus Low serial data signal circuit terminal 19 at the EBCM harness connector and terminal 1 at the yaw/lateral accelerometer sensor harness connector.
    • If greater than the specified range, test the serial data signal circuit for an open/high resistance.
  8. Test for infinite resistance between the CAN Bus High serial data signal circuit terminal 18 and the CAN Bus Low serial data signal circuit terminal 19.
    • If not the specified value, repair the serial data circuits for a short together.
  9. If all circuits test normal, replace the yaw/lateral accelerometer sensor. If the DTC resets, replace the EBCM.
