DTC C1275 G Sensor-Signal

C1275:

DTC Detecting Condition

Failsafe Function
Only the ABS, TCS (ESP) functions are inhibited. The ABS, TCS (ESP) 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 Volts - 4.5 Volts?
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 Volts

Incline the G-sensor to 90 degrees angle then measure the voltage between terminals 2 (+) and 3 (-) of the G-sensor connector.
Specification: approximately 3.5 Volts

Is the voltage within the specification?
NO
- Replace the G-sensor.
YES
- Replace the HECU then recheck.
