Circuit/System Testing
1. Test for HPCM DTC P0562.
瀚慞erform HPCM P0562 diagnosis if set.
2. Program the PIM with the latest software version and recheck for DTCs.
瀚慖f the DTC resets after programming or if the PIM already contains the latest software version, replace the PIM.

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
