DESCRIPTION
The ECM memory contains the programs for the normal and PWR shift patterns.
By following the programs corresponding to the signals from the pattern select switch assembly, park/neutral position switch and other various sensors, the ECM switches the shift solenoid valves on and off, and controls the transmission gear ratio.

Front Airbag Sensor RH Circuit Malfunction (B1610/13)
DESCRIPTION
The front airbag sensor RH consists of parts such as the diagnostic circuit and
the frontal detection sensor.
When the airbag sensor assembly receives signals from the frontal deceleration
sensor, it determines whether or not the SRS should be activated.
DTC B1610/13 is set when a ...
