Control Module Performance
DESCRIPTION
The ECM continuously monitors its main and sub CPUs. This self-check ensures
that the ECM is
functioning properly. If outputs from the CPUs are different and deviate from
the standards, the ECM will
illuminate the MIL and set a DTC immediately.
The ECM also monitors the cru ...
