STEERING WHEEL SENSOR
CAUTION: Do not drop or shock the G and yaw rate sensor.
CAUTION: Always carry out calibration if steering angle is
adjusted (Refer to IN THE EVENT OF A DISCHARGED
BATTERY
). This is necessary because the TCL/ASC-
ECU should update the G and yaw rate sensor
neutral point.

2. Turn the ignition switch to the "ON" position.
3. Use scan tool MB991958 to check the actuator test.
Item 09: Engine TCL Drive.
When the accelerator pedal is depressed at the same time that the
button for actuator test item 09 displayed on scan tool MB991958 is
pressed, the system prevents the engine speed from rising for three
seconds.
4. Turn the ignition switch to the "LOCK" (OFF) position.
5. Disconnect scan tool MB991958.
6. If defective, repair it. (Refer to TCL DIAGNOSIS

TCL SWITCH CHECK 1. Remove the TCL switch. (Refer to TCL SWITCH
).
2. Measure the resistance between terminal 1 and terminal 2 when the TCL
switch is pressed or released. If the values measured at the time correspond to
those in the table below, the resistance values are correct.
