1.
CHECK G SENSOR
With CONSULT
1. Remove G sensor.
2. Reconnect all harness connectors disconnected.
3. Place the G sensor on a flat table.
4. Turn ignition switch ON.
5. Select “G SENSOR” in “DATA MONITOR” mode of “ENGINE”
using CONSULT to check indications according to the following
conditions:
*: Check that voltage rises as the G sensor measurement condition changes in the order of (A), (B), and (C).
