DPS UNIT
The DPS module provides DC power to the mo-
tor. The amount and duration of that DC power is
determined by the inputs to the DPS module. The
direction in which the motor turns is changed by
reversing the polarity of the circuit current.
The DPS motor does not "spin", but rather turns in
very small increments based on the amount, du-
ration, and direction of DC power delivered by the
DPS module.
DPS Unit Protection
To protect the DPS electronic components, the
steering assist behavior will change as follows.
CONDITION
When motor internal
temperature reaches a certain
temperature (DPS continuously
estimates it)
DPS internal board temperature
is above 85°C (185°F)
DPS internal board temperature
is above 100°C (212°F)
When the DPS unit temperature is back within
normal operating range:
– Turn the ignition key OFF.
– Wait 30 seconds.
– Turn the ignition key ON.
Steering assist should resume normal operation.
DPS BEHAVIOR
Steering assist
will gradually
decrease.
Steering assist is
stopped.
