ELECTRICAL – LOW SPEED MANEUVERING GUIDANCE DEGRADATION
Issue
– When the vehicle is first started, PDC is fully operational (objects are detected and
shown visibly on the PIVI HMI and audibly through the speakers).
– Once the vehicle reaches 16kph, the PDC turns off as the speed threshold for
operation has been exceeded.
– As the vehicle slows below 16kph, a red box appears around the bird’s eye view on the
PIVI HMI indicated that PDC has degraded, however the surround camera (birds eye
view) continues to operate as designed.
– PDC audio warnings will not sound while in a degraded state with the red box shown.
– If the vehicle speeds up (above 16kph) then the red box disappears (as required
because PDC is 'OFF') but returns when the vehicle slows back down (below 16kph).
– This remains for the ignition cycle and is only healed after another cold start.
– There are no NFSM DTC's stored
Technicall Description
– This occurs due to the NFSM module receiving data outside of tolerance with regards
to tire pressure information sent over the CAN network
– Tire pressures above 400kpa (58PSI) will cause the low speed maneuvering guidance
to enter into a failed state once the vehicle travels above 16km/hr.
Status
– Ensure tire pressures are set to the vehicle specified values prior to performing
additional diagnosis
