Test Description

WARNING: This page is about a different variant/trim than selected.

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

  1. 1:  The Diagnostic System Check - Vehicle prompts the technician to complete some basic checks and store the Freeze Frame data on the scan tool, if applicable. This creates an electronic copy of the data taken when the fault occurred. The information is then stored in the scan tool for later reference.
  2. 3:  This step verifies the operation of the AIR solenoid valve.
  3. 8:  This step verifies the correct operation of the AIR shut-off valve.
  4. 11:  This step verifies the operation of the vacuum check valve.

Did the vacuum gage indicate pressure when the AIR pump was ON?		 - Go to Step 12  Go to Step 6 
6
  1. Turn OFF the ignition.
  2. Disconnect the electrical connector of the AIR solenoid valve.
  3. Connect a test lamp between the ignition positive voltage circuit of the AIR solenoid valve and a known good ground. Refer to Troubleshooting with a Test Lamp in Wiring Systems.
  4. Turn ON the ignition, with the engine OFF.
Did the test lamp illuminate?		 - Go to Step 7  Go to Step 14 
7
  1. Connect a test lamp between the ignition positive voltage circuit and the control circuit of the AIR solenoid valve. Refer to Troubleshooting with a Test Lamp in Wiring Systems.
  2. Command the AIR solenoid valve and the AIR pump ON with the scan tool.
Did the test lamp illuminate when the AIR solenoid valve and AIR pump were commanded ON?		 - Go to Step 16  Go to Step 13 
8 
  1. Turn OFF the ignition.
  2. Remove the AIR shut-off valve. Refer to Secondary Air Injection (AIR) Shut-Off Valve Replacement .
