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.

1. READ DATA LIST
HINT:
Using the Techstream to read the Data List allows the values or states of switches,
sensors, actuators and other items to be read without removing any parts. This non-intrusive
inspection can be very useful because intermittent conditions or sig ...
Front Airbag Sensor LH Circuit Malfunction (B1615/14)
DESCRIPTION
The front airbag sensor LH 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 B1615/14 is set when a ...
