(3)
Check if the DTC is set.
(4)
Turn the ignition switch to the "LOCK" (OFF) position.
Q:Is the DTC B223D set?
YES:
Check the occupant classification-ECU. If no
abnormality is found, replace the SRS-ECU. (Refer to P.
52B-326).
NO:
There is an intermittent malfunction such as poor
engaged connector(s) or open circuit (Refer to GROUP 00,
How to Cope with Intermittent Malfunction P.00-15).
DTC U0019: Bus Off (CAN-B)
M15204000971USA0000010000
⦆
If the DTC U0019 is set, be sure to diagnose the
CAN main bus line.
⦆
When replacing the ECU, always check that the
communication circuit is normal.
DIAGNOSTIC FUNCTION
If the CAN-B circuit malfunction occurs, the SRS-ECU
sets the DTC U0019.
JUDGMENT CRITERIA
Because of the CAN-B bus circuit malfunction, if SRS-
ECU becomes unable to perform the normal data
transmission, SRS-ECU determines that an
abnormality is present.
TROUBLESHOOTING HINTS
The CAN bus line may be defective
