Conditions for Clearing the MIL/DTC
WARNING: This page is about a different car, the 2007 Cadillac DTS. However, it is still accessible from the selected car via links, so may be relevant.
- The scan tool can be used to clear the DTC.
- The DTC is saved as history when the ALC sensor no longer sees battery voltage outside the normal range of 9-15.5 volts. The DTC will clear if the fault does not return after 50 consecutive ignition cycles.
