BT-50_01041
•
Similar to other current modules the PCM now allows to carry out the following
programming functions by means of M-MDS:
–
Programmable module installation (to replace PCM)
–
Module reprogramming (to update software calibration)
–
Programmable parameters (to input injector correction factors)
–
As-build data (to update As-build data)
–
Data reset (PCM and MAF sensor)
–
MAF learning (to adapt MAF sensor condition to PCM)
NOTE:
For replacement of the PCM certain procedures have to be followed (refer to the
chapter ‘Maintenance and Repair’).
A/C Cut-Off Control
•
Under the following engine operating conditions the PCM turns the A/C relay off to
improve driveability:
–
For a certain time when the accelerator-opening angle is 87.5 % or more.
–
Permanently when ECT is above 113 °C until temperature falls below 110 °C.
