Component Inspection

INFOID:0000000012198646

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).

Without 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.
