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. Check ETACS-ECU connector C-317 and KOS-ECU
connector C-102 for loose, corroded or damaged terminals,
or terminals pushed back in the connector.

Q:Is ETACS-ECU connector C-317 and KOS-ECU connector

C-102 in good condition?

YES:

Go to Step 3.

NO:

Repair the defective connector.

STEP 3. Check the wiring harness between KOS-ECU
connector C-102 (terminal No.39) and ETACS-ECU
connector C-317 (terminal No.5).

｠

Check the power supply line for open circuit.

Q:Is the wiring harness between KOS-ECU connector C-102

(terminal No. 39) and ETACS-ECU connector C-317

(terminal No. 5) in good condition?

YES:

Go to Step 4.

NO:

Repair the wiring harness.

STEP 4. Using scan tool MB991958, check data list.
Use the ETACS-ECU data list to check the signals related to the
ignition voltage.

DIAGNOSIS

NO:

Diagnose the ETACS-ECU. Refer to GROUP 54Ad,

Diagnosis P.54Ad-8.

STEP 5. Recheck for diagnostic trouble code.
Check again if the DTC is set to the WCM.

(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.)

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).

DTC B2204: Coding data mismatch

M14209100098USA0000010000

｠

When the DTC B2204 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
If the vehicle information data on the CAN bus lines is
different from that registered with KOS-ECU, KOS-
ECU sets the DTC B2204.

TECHNICAL DESCRIPTION (COMMENT)
KOS-ECU determines that the abnormality is present
when the vehicle information registered in it does not
match the vehicle information on the CAN bus lines.
