Component Inspection
INFOID:0000000012198042
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.
5. Check the voltage between ECM harness connector terminal
and ground.

P1650 STARTER MOTOR RELAY 2
P1650 STARTER MOTOR RELAY 2
Description
INFOID:0000000012198043
ECM controls ON/OFF state of the starter relay, according to the engine and vehicle condition. On the other
hand, models with the Intelligent Key System transmit a control signal to IPDM E/R by way of BCM via CAN
communication.
Under normal conditions, ECM controls and maintains the starter relay in OFF state during engine running or
“D” position.
When detecting a decrease in engine speed due to rapid deceleration or heavy load condition, ECM controls
and reactivates the starter relay.
IPDM E/R detects a control state of starter relay and starter control relay and transmits a feedback signal to
ECM via CAN communication.
