•

P0017: Crankshaft Position - Camshaft Position Correlation Bank 1 Sensor B

•

P0018: Crankshaft Position - Camshaft Position Correlation Bank 2 Sensor A

•

P0019: Crankshaft Position - Camshaft Position Correlation Bank 2 Sensor B

•

P2404: Evap System Leak Detection Pump Sense Circuit Range/Performance

•

P0011: “A” Camshaft Position - Timing Over-Advanced or System Performance Bank 1

•

These new files contain the following enhancements:

•

Enhanced logic for the self-diagnosis program of the ECM and to optimize stabilization of
fuel pressure.

•

Optimized fuel trim providing stabilized engine combustion during Exhaust Gas Recirculation
(EGR) valve operation.

•

Enhanced logic to prevent the ELCM pump from seizing.

•

Self-shutdown logic for the starter motor relay program, eliminating the possibility frozen
relay contacts.
