(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.

DTC B2206: Chassis number does not match

M15410600066USA0000010000

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.

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.
