To prevent damage to scan tool (MB991958), always turn
the ignition switch to the "LOCK" (OFF) position before
connecting or disconnecting scan tool (MB991958).

(1)

Connect scan tool MB991958 to the data link connector.

(2)

Turn the ignition switch to the "ON" position.

(3)

Check if the DTC is set.

DTC B2352: Antenna fail

M14209200021USA0000010000

DTC SET CONDITION
WCM sets the DTC B2352 when open or short circuit
to the ground in the antenna is detected.

TECHNICAL DESCRIPTION (COMMENT)
When the ignition switch is turned ON, WCM transmits
signal to the antenna. When the antenna is found

faulty, WCM determines that the abnormality is
present.

If there is any problem in the CAN bus lines, an incorrect
diagnostic trouble code may be set. Prior to this diagnosis,
diagnose the CAN bus lines. (Refer to GROUP 54D, Trouble
code diagnosis P.54D-17).

TPMS DTC SET CONDITION
WCM incorporates the EEPROM (nonvolatile memory). The
EEPROM stores the TPMS information. If the data in EEPROM
fails, this code is set.
