Function summaryInternal control module random access memory (ram) error
Description
The ecm continuously monitors its own internal memory status, internal
circuits, and output signals
transmitted to the throttle actuator. This self-check ensures that the ecm is
functioning properly. If any
malfunction is detected, the ecm sets the appropriate dtc and illumina ...
Throttle actuator control motor current range / performance
Description
The etcs (electronic throttle control system) has a dedicated power supply
circuit. The voltage (+bm)
is monitored and when it is low (less than 4 v), the ecm determines that there
is a malfunction in the
etcs and cuts off the current to the throttle actuator.
When the volt ...
Short in motor circuit
Description
The power steering ecu supplies current to the power steering motor through
this circuit.
Inspection procedure
Reconfirm dtc
Check for dtc.
Ok:
dtc is not output.
Replace power steering ecu ...
