Turbine Speed Sensor Circuit No Signal
DESCRIPTION This sensor detects the rotation speed of the input turbine. By comparing the input turbine speed signal (NT) with the counter gear speed sensor signal (NC), the ECM detects the shift timing of the gears and appropriately controls the engine torque and hydraulic pressure accor ...

System description
1. GENERAL This system uses ultrasonic sensors to detect any obstacles at the corners and the rear of the vehicle. The system then informs the driver of the distance between the sensors and the obstacles as well as their positions by indicating them on the clearance sonar displ ...

Installation
1. INSTALL CENTER AIRBAG SENSOR ASSEMBLY Check that the ignition switch is off. Check that the battery negative (-) terminal is disconnected. CAUTION: After disconnecting the negative battery terminal, wait for at least 90 seconds before starting the operation. &n ...
