DIAGNOSIS

DIAGNOSTIC TROUBLE CODE PROCEDURES

DTC B1731: Engine Control Module communication timeout

M14209100004USA0000010000

｠

When the DTC B1731 is set, be sure to diagnose
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 position, it is
judged as abnormal.

DIAGNOSIS

Required Special Tools:

｠

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

｠

MB991824: Vehicles Communication Interface (V.C.I.)

｠

MB991827: M.U.T.-III USB Cable

DIAGNOSIS

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

Data link

connector

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 54D,

Diagnosis P.54D-17).

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 13Ab,

Diagnostic trouble code chart P.13Ab-44).

NO:

 Go to Step 3.

STEP 3. Recheck for diagnostic trouble code.
Check again if the DTC is set to the KOS-ECU.

(1)

Erase the DTC.

(2)

Turn the ignition switch from "LOCK" (OFF) position to "ON"
position.

(3)

Check if DTC is set.

(4)

Turn the ignition switch to the "LOCK" (OFF) position.

Q:Is the DTC set?

YES:

 Replace KOS-ECU and register the ID codes. (Refer

to P.42B-12.) After registering the ID codes, go to Step
4.

NO:

 The trouble can be an intermittent malfunction (Refer

to GROUP 00 - How to use Troubleshooting/inspection
Service Points - How to Cope with Intermittent
Malfunction P.00-15).

STEP 4. Recheck for diagnostic trouble code.
Check again if the DTC is set to the KOS-ECU.

(1)

Erase the DTC.

(2)

Turn the ignition switch from "LOCK" (OFF) position to "ON"
position.

(3)

Check if DTC is set.
