Diagnostic Test

CHECK FOR AN ACTIVE DTC
1. Turn the ignition on.
2. With the scan tool, read DTCs.
  Does the scan tool display this DTC as active?
  
  Yes
  - Go To 2.
  No
  - Test complete, the condition or conditions that originally set this DTC are not present at this time. Using the wiring diagrams as a guide, check all related splices and connectors for signs of water intrusion, corrosion, pushed out or bent terminals, and correct pin tension.
  - Refer to Standard Procedure and perform the BODY VERIFICATION TEST.

1. Turn the ignition off.
2. Disconnect the Front Headlamp Level Sensor harness connector.
3. Turn the ignition on.
4. Measure the voltage of the (L961) Front Headlamp Leveling Sensor 5 Volt Supply circuit.
  Is the voltage between 4.5 and 5.5 volts?
  
  Yes
  - Go To 3.
  No
  - If the voltage is below 4.5 volts, repair the (L961) Front Headlamp Leveling Sensor 5 Volt Supply circuit for a short to ground or an open/high resistance.
  - If the voltage is above 5.5 volts, repair the (L961) Front Headlamp Leveling Sensor 5 Volt Supply circuit for a short to voltage.
  - Refer to Standard Procedure and perform the BODY VERIFICATION TEST.
