Hi Norm, My name is***** will be glad to help. Click on this link for your troubleshooting information. The switch you replaced was it a pressure switch in an air manifold or the switch for the clutch pedal?

also if an air switch did this fault begin after replacing the switch or the reason the switch was replaced? Just want to be sure if both old switches and new switch were the same normally open or normally closed. Let me know

Air switch on manifold was replaced for this problem, no change.

gotchya. Does jumping the two wires together and disconnecting them throw and also stop this code?

Customer reply replied 2 years ago
When disconnect code goes out. Switch is normally closed so disconnecting it is the same as releasing the brakes
