5-Volt Reference 1 Circuit

Possible Causes:



It may be possible to locate the fault by disconnecting one component at a time from the 5-volt reference circuit while viewing the 5-Volt Reference circuit parameter on the scan tool. The scan tool parameter would change from Fault to OK when the source of the fault is disconnected.
 
If all 5-volt reference components have been disconnected and a Fault is still indicated, the fault may exist in the wiring harness.
 

Trouble Code: P0642

Possible Causes:



It may be possible to locate the fault by disconnecting one component at a time from the 5-volt reference circuit while viewing the 5-Volt Reference circuit parameter on the scan tool. The scan tool parameter would change from Fault to OK when the source of the fault is disconnected.
 
If all 5-volt reference components have been disconnected and a Fault is still indicated, the fault may exist in the wiring harness.
