Some affected vehicles may display an illuminated MIL with DTC P0420: Warm Up Catalyst Efficiency Below Threshold, recorded in the ECM. An incorrect parameter in the judgment criteria may cause a false MIL (mis-detection of a fault when an abnormal condition is not present). This TSB provides dealers with a procedure to reprogram the ECM with new software to correct the condition.
