Road Test
ROAD TEST PROBLEM SYMPTOM CONFIRMATION HINT: The dynamic radar cruise control system has 2 cruise control modes: constant speed control mode and vehicle-to-vehicle distance control mode. Vehicle-to-vehicle distance control mode is selected by default when the dyna ...

Side Airbag Sensor LH Circuit Malfunction (B1625/22)
DESCRIPTION The side airbag sensor assembly LH consists of parts such as the safing sensor, the diagnostic circuit and the lateral deceleration sensor. When the airbag sensor assembly receives signals from the lateral deceleration sensor, it determines whether or not the SRS should be activate ...

Transmission Fluid Temperature Sensor "A" Performance (P0711)
DESCRIPTION The No. 1 ATF temperature sensor converts the fluid temperature into a resistance value for use by the ECM. The ECM applies a voltage to the temperature sensor through terminal THO1 of the ECM. The sensor resistance changes with the ATF temperature. As the temperature becomes hi ...
