Issue:
Customers may report that the Stop Start function is intermittently
not working for long periods of time during a drive cycle.
Cause:
There are many reasons that the Stop Start function will inhibit
operation during periods of a drive cycle. These include, but are
not limited to, electrical draw loads placed on the system as a
result of temperature, HEVAC operation, Steering Wheel input and
Electrical Accessory functions operating. These inhibit parameters
are software functionality performance aids to ensure that the
battery health remains in optimum condition. The inhibit function is
used to estimate the cold cranking VSOF (Voltage State of
Function) to ensure that the vehicle can execute a full Stop/Start
sequence when required.
Action:
In the event of a customer report of intermittent operation of
Stop/Start system please follow the instructions detailed. Use
approved diagnostics to assess the Stop Start Health. It is
imperative that technicians use the Stop Start Health application
on Pathfinder to determine the inhibitor of the system. If estimate
cold cranking voltage at present state of charge VSOF (Voltage
State of Function) is not the only inhibit code stored, diagnose the
other inhibit states in isolation of this SSM.
If VSOF (Voltage State of Function) is the only inhibit follow
the diagnostic procedure below.
Note: A further communication including further model
years will be released in due course.
