1. Disconnect the G-sensor connector and connect tool No. MB991348, or equivalent, between the terminal of the disconnected connector.
2. Turn the ignition switch to "ON" and take a reading of the output voltage between terminals Nos. 2 and 3. The standard value is 2.4 - 2.6 volts.
3. With the special tool still connected, secure the G-sensor so that the FRONT mark on the sensor mounting surface is facing straight down, and
then take a reading of the output voltage between terminals Nos. 2 and 3. The standard value is 3.4 - 3.6 volts.
4. If the voltage is outside the standard value, after checking to be sure that there is no abnormality in the power supply and earth wires, replace the
G-sensor.
