Test Description

WARNING: This page is about a different car, the 2006 Chevrolet Corvette. 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. 3:  Tests for the proper operation of the circuit in the low voltage range.
  2. 4:  Tests for the proper operation of the circuit in the high voltage range. If the fuse in the jumper opens when you perform this test, the signal circuit is shorted to ground.
  3. 5:  Tests for a short to voltage in the 5-volt reference circuit.
  4. 6:  Tests the bias voltage of the yaw rate sensor.
