DTC Parameters
WARNING: This page is about a different car, the 2002 Saturn LW200, 2002 Saturn L200, and 2002 Saturn L100. However, it is still accessible from the selected car via links, so may be relevant.
DTC sets when ignition voltage is present at PCM brake switch input while vehicle is accelerated 8 times in one ignition cycle in the following manner:
- Vehicle speed is less than 5 MPH for 6 seconds.
- Then vehicle speed is 5-20 MPH for 4 seconds.
- Then vehicle speed is more than 20 MPH for 6 seconds.
DTC diagnostic runs once per ignition cycle. PCM will only fail DTC after 15 minutes have elapsed during which all 8 tests must have failed.
