DIAGNOSTIC TROUBLE CODE PROCEDURES

DTC B1731: Engine Control Module communication timeout

CAUTION

• When the DTC B1731 is set, be sure to diag-

nose the CAN bus line.

• When replacing the ECU, always check that 

the communication circuit is normal.

.

DTC SET CONDITION

KOS-ECU checks that the Engine Control Module 
data has been received via the CAN bus lines, and if 
not, sets the DTC No. B1731.

.

TECHNICAL DESCRIPTION (COMMENT)

If no data [ETACS transmits engine random number 
data to KOS-ECU via the CAN bus lines] is received 
from the Engine Control Module via the CAN bus 
lines when the ignition switch is turned to ON posi-
tion, it is judged as abnormal.

.

TROUBLESHOOTING HINTS

• Malfunction of CAN bus line

• Malfunction of KOS-ECU

• Malfunction of engine control module

• Malfunction of ETACS-ECU

DIAGNOSIS

Required Special Tools:

• MB991958: Scan Tool (M.U.T.-III Sub Assembly)

DIAGNOSIS

TSB Revision

KEYLESS OPERATION SYSTEM (KOS)

42B-38

STEP 1. Using scan tool MB991958, diagnose the CAN bus 
line.

CAUTION

To prevent damage to scan tool (MB991958), always turn 
the ignition switch to the "LOCK" (OFF) position before 
connecting or disconnecting scan tool (MB991958).
(1) Connect scan tool MB991958 to the data link connector.
(2) Turn the ignition switch to the "ON" position.
(3) Diagnose the CAN bus line.
(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the CAN bus line found to be normal?

YES : Go to Step 2.
NO :  Repair the CAN bus line. (Refer to GROUP 54C, 

Diagnosis 

P.54C-17

). On completion, go to Step 2.

STEP 2. Using scan tool MB991958, read the Engine 
Control Module diagnostic trouble code
Check again if the DTC is set to the engine control module.
Q: Is the DTC set?

YES : Troubleshoot the MFI system (Refer to GROUP 13A, 

Diagnostic trouble code chart 

P.13A-49

 <2.4L 

Engine> or GROUP 13B, Diagnostic trouble code 
chart 

P.13B-50

 <3.0L Engine>).

NO :  Go to Step 3.

STEP 3. Using scan tool MB991958, read the other system 
diagnostic trouble code.
Check if DTC U0100 is set to ETACS-ECU.
Q: Is the DTC set?

YES : Go to Step 5.
NO :  Go to Step 4.
