DTC U1414: Defective Coding Data

M15204001011USA0000010000

｠

If the DTC U1414 is set, diagnose the CAN main
bus lines.

｠

When replacing the ECU, always check that the
communication circuit is normal.

DIAGNOSTIC FUNCTION
If the vehicle information data is not registered to the
SRS-ECU, the SRS-ECU sets the DTC U1414.

JUDGEMENT CRITERIA
When  the  coding  data  (vehicle  information)  from
ETACS-ECU is not received, SRS-ECU determines
that the abnormality is present.

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 ETACS-ECU
diagnostic trouble code
Check if DTC is set to the ETACS-ECU.

Q:Is the DTC set?

YES:

 Troubleshoot the ETACS-ECU (Refer to GROUP 54Ad,

Diagnosis P.54Ad-8).

NO:

SRS AIR BAG DIAGNOSIS

DIAGNOSTIC FUNCTION
If the vehicle information data is not registered to the
SRS-ECU, the SRS-ECU sets the DTC U1415.

JUDGEMENT CRITERIA
With  the  global  coding  counter  value  "0",  if  all  the
global  coding  data  (vehicle  information)  are  not

stored, the SRS-ECU determines that a problem has
occurred.
