Need help trouble shooting LTPWS light
I need help trouble shooting a LTPWS light. I started getting the Service LTPWS light on the Driver Information Center after I swapped the rear tires and tire pressure sensors to a new set of rear wheels. So, I suspect that one or both sensors was damaged during the swap.
This is for a 1993 ZR-1. When ever I start the car, the LTPWS light is not on. After I drive about 3-4 miles, Service LTPWS lights up, and stays on. I want to figure out which rear wheel has the bad sensor, but I can't get a code number. I have tried to get a a code number using a Tech 1, but it reports no DTC even though the Service LTPWS light is on. I have also used a scan tool (DataMaster), but it reports no codes as well. Is there something special about the way the LTPWS faults are reported? The FSM says to read the codes to tell which wheel sensor is bad, but it isn't working for me. Any ideas? Thanks, Jim
