STEP 6. Check the battery power supply circuit to the
ETACS-ECU. Measure the voltage at ETACS-ECU
connector C-307.
(1) Disconnect ETACS-ECU connector C-307 and measure the
voltage available at the wiring harness side of the
connector.
(2) Turn the ignition switch to the "LOCK" (OFF) position.
(3) Measure the voltage between terminal 2 and ground.
• The voltage should measure approximately 12 volts
(battery positive voltage).
Q: Is the measured voltage approximately 12 volts (battery
positive voltage)?
YES : Go to Step 8.
NO : Go to Step 7.
STEP 7. Check the wiring harness between ETACS-ECU
connector C-307 (terminal 2) and the fusible link (36).
Check the power supply line for open circuit.
Q: Is the wiring harness between ETACS-ECU connector
C-307 (terminal 2) and the fusible link (36) in good
condition?
YES : No action is necessary and testing is complete.
NO : The wiring harness may be damaged or the
connector(s) may have loose, corroded or damaged
terminals, or terminals pushed back in the connector.
Repair the wiring harness as necessary.

STEP 8. Using scan tool MB991958, check data list.
Check the power supply fuse voltage.
CAUTION
To prevent damage to scan tool MB991958, always turn the
ignition switch to the "LOCK" (OFF) position before con-
necting or disconnecting scan tool MB991958.
(1) Connect scan tool MB991958. Refer to "How to connect the
Scan Tool (M.U.T.-III)
."
(2) Check the ETACS data list.
• Turn the ignition switch to the "LOCK" (OFF) position.
Q: Does the scan tool MB991958 display the item "voltage
sensing of IOD Line" is normal condition?
YES : Go to Step 9.
NO : Replace the ETACS-ECU.
STEP 9. Recheck for diagnostic trouble code.
Check again if the DTC is set to the ETACS-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 the ETACS-ECU.
NO : The trouble can be an intermittent malfunction (Refer
to GROUP 00, How to Cope with Intermittent
Malfunction
).
Item No.

DTC B222C: Coding incomplete
.
TROUBLE JUDGMENT
If the ETACS-ECU is in the initial state or the variant
coding is incomplete, the ETACS-ECU sets DTC
B222C.
.
TROUBLESHOOTING HINTS
• Variant code not written
• The ETACS-ECU may be defective.
DIAGNOSIS
Required Special Tools:
• MB991958: Scan Tool (M.U.T.-III Sub Assembly)
• MB991824: Vehicle Communication Interface (V.C.I.)
• MB991827: M.U.T.-III USB Cable
• MB991910: M.U.T.-III Main Harness A (Vehicles with
CAN communication system)
Recheck for diagnostic trouble code.
Check again if the DTC is set to the ETACS-ECU.
CAUTION
To prevent damage to scan tool MB991958, always turn the
ignition switch to the "LOCK" (OFF) position before con-
necting or disconnecting scan tool MB991958.
(1) Connect scan tool MB991958. Refer to "How to connect the
Scan Tool (M.U.T.-III)
."
(2) Turn the ignition switch to the "ON" position.
(3) Perform the variant coding to the ETACS-ECU.
(4) Erase the DTC.
(5) Turn the ignition switch from "LOCK" (OFF) position to "ON"
position.
(6) Check if DTC is set.
(7) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the DTC set?
YES : Replace with the coded ETACS-ECU.
NO : The diagnosis is complete.

DTC B2206: Chassis number does not match
CAUTION
If DTC B2206 is set, always diagnose the CAN
bus line.
.
TROUBLE JUDGMENT
If the registered chassis number is different from the
chassis number transmitted on the CAN bus lines,
the ETACS-ECU sets DTC B2206.
.
JUDGMENT CRITERIA
If the chassis number registered to ETACS-ECU and
the chassis number on CAN bus lines do not match,
the ETACS-ECU determines that a problem has
occurred.
.
TROUBLESHOOTING HINTS
• Chassis number not written
• The ETACS-ECU may be defective.
• The engine control module may be defective.
• The CAN bus line may be defective.
DIAGNOSIS
Required Special Tools:
• MB991958: Scan Tool (M.U.T.-III Sub Assembly)
• MB991824: Vehicle Communication Interface (V.C.I.)
• MB991827: M.U.T.-III USB Cable
• MB991910: M.U.T.-III Main Harness A (Vehicles with
CAN communication system)
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 con-
necting or disconnecting scan tool MB991958.
(1) Connect scan tool MB991958. Refer to "How to connect the
Scan Tool (M.U.T.-III)
."
(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,
).
