Only the ABS, TCS (ESC) functions are inhibited. The ABS,TCS(ESC) warning lamps are ON, but the EBD warning lamp OFF.

INSPECTION PROCEDURE
1. CHECK OPEN/SHORT IN CIRCUIT OF G-SENSOR.
1. Turn the ignition switch ON.
2. Measure the output voltage between terminals 2 (+) and 3 (-) of the G-sensor connector.
Is the voltage within 0.6 V - 4.5 V?

NO - Repair an open or short in the circuit between the G-sensor and the HECU.

YES - Check installing of G-sensor.

2. CHECK INSTALLING OF G-SENSOR
Visually check for the installing of the G-sensor.
Be sure to install the G-sensor with the arrow mark to be facing forward direction.
Is it installed correctly?

NO - Reinstall the G-sensor and recheck.

YES - Check output voltage in G-sensor connector.

3. CHECK OUTPUT VOLTAGE IN G-SENSOR CONNECTOR.
Turn the ignition switch ON.
Measure the voltage between terminals 2 (+) and 3 (-) of the G-sensor connector.

Specification: approximately 2.5 V

Incline the G-sensor to 90° angle then measure the voltage between terminals 2 (+) and 3 (-) of the G-sensor connector.

Specification: approximately 3 - 5 V

Is the voltage within the specification?

NO - Replace the G-sensor.

YES - Replace the HECU then recheck
