-
Correct the PWM ratio of the charge air control valve. At low atmospheric pressure, a greater PWM ratio is required to obtain the same air
mass/combustion.
-
Correct the purge PWM ratio. At low atmospheric pressure, a greater PWM ratio is required to obtain the same purge flow.
-
Protect the turbo from overrevving at low atmospheric pressure by limiting the max. permissible air mass per combustion.
-
Block certain diagnoses at pressure lower than 72 kPa.
Once the ignition has been turned off, all the sensors supplied with 5V are activated for 15 minutes. After 15 minutes, only the memory is active.
Adapted values are stored in the memory.
Adaptation is important to performance, drivability, fuel consumption and emissions. The control module must therefore not be disconnected or in any
other way be de-energized unnecessarily.
Diagnostics
-
If the control module program memory ROM or working memory RAM is defective, diagnostic trouble code P0605 will be generated.
-
If any internal function that affects throttle control is faulty, trouble codes P1601-P1611, P1613-P1614 or P1621 will be generated.
-
If the atmosphere pressure sensor is defective, diagnostic trouble codes P1631-P1633 will be generated. The starting value for charge air pressure
will be used as a substitute value and purging will be blocked.
