Diagnostic Test

APS INTERMITTENT DIAGNOSTIC PROCEDURE 

1. The DTC is not active at this time. The following may help to identify an intermittent condition: 
   • Check for any Service Bulletins that may apply.
   • Inspect the related wiring harness and connectors. Look for any chafed, pierced, pinched, partially broken wires, or broken, bent, pushed out, or corroded terminals.
   • Perform a voltage drop test on the circuits between the component and the applicable module.
   • If multiple DTCs are set, use a wiring schematic and inspect any common power or ground circuits.
   • Inspect and clean all related ground circuits.
   • Use the scan tool to perform any System Test or Actuations to the component(s) that may cause the DTC to set.
   • Perform a wiggle test on the related wiring and connectors while monitoring the scan tool. Look for the DTC to change to active or supporting data to change during the test.
