Lost communication with driver side - side airbag sensor assembly
Description The side airbag sensor lh consists of part including the diagnostic circuit and the lateral deceleration sensor. When the center airbag sensor receives signals from the lateral deceleration sensor, it determines whether or not the srs should be activated. Dtc b1622/81 is ...

Shift solenoid "d" performance (shift solenoid valve s4)
System description The ecm uses signals from the output shaft speed sensor and input speed sensor to detect the actual gear position (1st, 2nd, 3rd or o/d gear). Then the ecm compares the actual gear with the shift schedule in the ecm memory to detect mechanical problems of the shift s ...

For vehicles equipped with mobile communication systems
Install the antenna as far away from the ecu and sensors of the vehicle electronic systems as possible. Install an antenna feeder at least 20 cm (7.87 In.) Away from the ecu and sensors of the vehicle electronic systems. For details about ecu and sensor locations, refer to the sec ...
