DTC P16F3
- Control Module Redundant Memory Performance
DTC P2610
- Control Module Ignition Off Timer Performance
Circuit/System Description
This diagnostic applies to internal microprocessor integrity conditions within the engine control module (ECM) and the throttle actuator control
(TAC) system. This diagnostic also addresses if the ECM is not programmed.
The ECM monitors its ability to read and write to the memory. It also monitors a timing function. The ECM and the TAC processors are used to
monitor the TAC system data. Both processors monitor the other processors data to verify that the indicated APP calculation is correct. The ECM
performs an intrusive test in order to confirm that the APP signals are not shorted together. The ECM accomplishes this by pulling the APP sensor
2 low momentarily and looking for sensor 1 to also be pulled low.
