DTC B222C: Coding incomplete
.
TROUBLE JUDGEMENT
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 JUDGEMENT
If the registered chassis number is different from the
chassis number transmitted on the CAN bus lines,
the ETACS-ECU sets DTC B2206.
.
JUDGEMENT 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,
).
STEP 2. Using scan tool MB991958, read the engine
control module diagnostic trouble code.
Check if DTC is set to the engine control module.
Q: Is the DTC set?
YES : Troubleshoot the engine (Refer to GROUP 13A,
Diagnostic Trouble Code Chart
).
NO : Go to Step 3.

DTC B2215: ECU internal error
.
TROUBLE JUDGEMENT
When the ETACS-ECU internal error count reaches
"255," DTC B2215 is set.
.
TROUBLESHOOTING HINTS
• The ETACS-ECU may be defective.
DIAGNOSIS
Replace the ETACS-ECU.
DTC B2353: Ignition power supply (low input)
DTC B2354: Ignition power supply (high input)

TROUBLE JUDGMENT
These DTCs are set when the ignition power supply
voltage decreases to the specified value or less
(DTC B2353) or increases to the specified value or
more (DTC B2354). However, when the status
returns to normal, the DTCs B2353 and B2354 are
automatically erased.
.
TECHNICAL DESCRIPTION (COMMENT)
The power supply circuit or the ETACS-ECU may
have a problem.
.
TROUBLESHOOTING HINTS
• The power supply circuit may be defective.
• The battery may be defective.
• The generator may be defective.
• The ETACS-ECU may be defective.
