2 CHECK G SENSOR. 
  1. Turn ignition switch to OFF.
  2. Remove G sensor from vehicle.
  3. Connect connector to G sensor.
  4. Turn ignition switch to ON.
  5. Measure voltage between G sensor connector terminals.

Connector & terminal: 
(R70) No. 2 (+) - No. 3 (-) 		 Is the voltage 2.1 - 2.5 V when G sensor is horizontal? Go to step 3.  Replace G sensor.
3 CHECK G SENSOR. 
Measure voltage between G sensor connector terminals.
Connector & terminal: 
(R70) No. 2 (+) - No. 3 (-) 		 Is the voltage 3.6 - 4.1 V when G sensor is inclined forwards to 90°? Go to step 4.  Replace G sensor.
4 CHECK G SENSOR. 
Measure voltage between G sensor connector terminals.
Connector & terminal: 
(R70) No. 2 (+) - No. 3 (-) 		 Is the voltage 0.5 - 1.0 V when G sensor is inclined backwards to 90°? G sensor is normal. Replace G sensor.
5 CHECK G SENSOR. 
  1. Turn ignition switch to OFF.
  2. Connect select monitor connector to data link connector.
  3. Turn select monitor into {BRAKE CONTROL} mode.
  4. Set the display in the {Current Data Display & Save} mode.
  5. Read the G sensor output voltage.
 Is the indicated reading 2.1 - 2.5 V when the vehicle is in horizontal position? Go to step 6.  Replace G sensor.
6 CHECK G SENSOR. 
  1. Remove console box.
  2. Remove G sensor from vehicle. (Do not disconnect connector.)
  3. Read the select monitor display.
 Is the indicated reading 3.6 - 4.1 V when G sensor is inclined forwards to 90°? Go to step 7.  Replace G sensor.
7 CHECK G SENSOR. 
Read the select monitor display.		 Is the indicated reading 0.5 - 1.0 V when G sensor is inclined backwards to 90°? G sensor is normal. Replace G sensor.
