On Park Brake Release Failure
No Sub Type Information
Parking Brake release is inhibited
1. The digital input of BBM responsible for activating Remote Parking Brake Release Inhibition (function CtaBsPBReleaseInhibit_stat us) was active while vehicle speed was above 10km/h.
2.The digital input of BBM responsible for inhibiting Remote Parking Brake Release Inhibition (function CtaBsPBReleaseInhibCancel
_stat) has been active for more than 60s (duration defined by P1KKE).
Diagnostic Service 14. No additional action is needed.
11. The digital input of BBM responsible for activating Remote Parking Brake Release Inhibition (function CtaBsPBReleaseInhibit_status) was active while vehicle speed was above 10km/h(speed defined by development parameter P1KKD). This is an assumption that there is a failure in the bodybuilder equipment because function should only be requested at standstill.
WORKSHOP ACTION:
Recommendation is to check the equipment feeding this BBM digital input.
2. The digital input of BBM responsible for inhibiting Remote Parking Brake Release Inhibition (function CtaBsPBReleaseInhibCancel_stat) has been active for more than 60s (duration defined by P1KKE). This is an assumption that the emergency PB release switch is stucked in position pushed.
WORKSHOP ACTION:
Recommendation is to check the switch and wire feeding this BBM digital input
