Inspection Procedure

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 0.6V ~ 4.5V?

NO 

• Repair an open or short in the circuit between the G-sensor and the HECU.

YES 

• 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

Turn the ignition switch ON.

Measure the voltage between terminals 2 (+) and 3 (-) of the G-sensor connector.

Specification: approximately 2.5V

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

Specification: approximately 3.5V

Is the voltage within the specification?

NO 

• Replace the G-sensor.

YES 

• Replace the HECU then recheck.
