@ -45,7 +45,18 @@ Braking should be supported through given ABS pump that has ACC braking capabili
The ABS can brake if it can be coded for ACC (Byte16-Bit5 set to 0) and coding is accepted.
Currently, there is no braking below 15 km/h with MK60EC1 H31+ pump. The MK60EC1 H46 pump which supports EPB should allow braking with ACC messages down till 0 km/h but code has to be written yet.
Currently, there is no braking below 15 km/h with MK60EC1 H31+ pump.
The MK60EC1 H46 pump which supports EPB does allow braking till 0 IF a EPB system has been retrofitted and the proper coding has been done.
Coding needed:
Byte 16 bit 5 to 0; Allow listening to mMotor_Bremse message,
Byte 18 bit 2 to 1; Follow 2 Stop activation,
One issue remaining is that once at standstill the ABS faults out with:
01314 - Engine Control Module.
008 - Implausible Signal
This could probably be circumvented but more testing is needed.
A car with stock stop&go ACC functionality should naturally be able to brake down till 0 with ACC message.
