2. Disconnect ECM harness connector.

3. Check the continuity between G sensor harness connector and ECM harness connector.

Is the inspection result normal?

YES

>> GO TO 9.

NO 

>> Repair or replace error-detected parts.

9.

CHECK ECM GROUND CIRCUIT

Check the continuity between ECM harness connector and ground.

Is the inspection result normal?

YES

>> Check intermittent incident. Refer to 

GI-45, "Intermittent Incident"

.

NO 

>> Repair or replace error-detected parts.

10.

CHECK SENSOR POWER SUPPLY CIRCUIT

1. Turn ignition switch OFF.

2. Disconnect ECM harness connectors and each sensor harness connectors

3. Check harness connector for short to power and short to ground, between the following terminals.

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.

INFOID:0000000012198044

DTC DETECTION LOGIC

NOTE:

• If DTC P1650 is displayed with DTC U1001, perform the trouble diagnosis for DTC U1001. Refer to 

EC-195,

"DTC Logic"

.

• If DTC P1650 is displayed with DTC P0607, perform the trouble diagnosis for DTC P0607. Refer to 

EC-419,
