Test Description

WARNING: This page is about a different car, the 2004 Pontiac Vibe. However, it is still accessible from the selected car via links, so may be relevant.

The numbers below refer to the step numbers on the diagnostic table.

  1. 7:  Tests to see if the malfunction is caused by the inflatable restraint side impact module.
  2. 8:  Tests to see if the malfunction is caused by the inflatable restraint side impact module.
  3. 10:  If DTC B0115 is present, test for a short between the Side Impact Module - Left - High and the Side Impact Module - Left - Low circuits. If DTC B0116 is present, test the Side Impact Module - Left - High and the Side Impact Module - Left - Low circuits for an open or high resistance. If DTC B0117 is present, test the Side Impact Module - Left - High and the Side Impact Module - Left - Low circuits for a short to ground. If DTC B0118 is present, test the Side Impact Module - Left - High and the Side Impact Module - Left - Low circuits for a short to voltage.
