DTC Description

INFOID:0000000010702992

CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.

DTC CONFIRMATION PROCEDURE

1.

PERFORM DTC CONFIRMATION PROCEDURE

1.

Turn ignition switch ON.

2.

Check 1st trip DTC.

Is 1st trip DTC detected?

YES

>> Proceed to 

ECM-302, "Diagnosis Procedure"

.

NO-1

>> To check malfunction symptom before repair: Refer to 

GI-41, "Intermittent Incident"

.

NO-2

2.

Erase DTC.

3.

Perform “DTC Confirmation Procedure”. Refer to 

ECM-302, "DTC Description"

.

Engine operating condition in fail-safe mode

Fail safe mode

Vehicle behavior

Traveling con-
trol mode

Accelerator an-
gle variation 
control

ECM controls the accelerator pedal depression speed to make it slower than actual speed. This 
causes a drop in accelerating performance and encourages the driver to repair malfunction.
NOTE:
ECM does not control the accelerator pedal releasing speed.

Engine output 
control

ECM reduces the engine output, according to the rise in engine speed. This reduces the vehicle 
speed to encourage the driver to repair malfunction.

P0611 ECM PROTECTION

DTC Description

INFOID:0000000010702994

This DTC is detected when the ECM protective function is activated due to an extreme temperature increasein
ECM, resulting from severe conditions such as heavy load driving.

DTC DETECTION LOGIC

POSSIBLE CAUSE

ECM overheating 

FAIL-SAFE

Not applicable

DTC CONFIRMATION PROCEDURE

1.

PERFORM DTC CONFIRMATION PROCEDURE

This DTC is displayed as protection function history. If no malfunction is detected after the diagnosis, the cus-
tomer must be informed of the activation of the protection function.

DTC Description

INFOID:0000000010702996

This DTC is detected when the ECM-integrated injector driver unit has a malfunction.

DTC Logic

INFOID:0000000010702997

DTC DETECTION LOGIC

POSSIBLE CAUSE

• Harness or connectors (Fuel injector circuit is open or shorted.)
• Battery power supply
• ECM (Injector driver unit)

FAIL-SAFE

NOTE:
Fail-safe mode may not start depending on malfunction type of ECM.
