DTC C1047: FR wheel speed sensor control phase time exceeded

M13502000924USA0000010000

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).

CIRCUIT OPERATION

｠

The  wheel  speed  sensor  is  a  kind  of  a  pulse  generator.  It
consists of encoders (a plate on which north and south pole
sides of the magnets are arranged alternately) for detecting
the  wheel  speed  which  rotates  at  the  same  speed  of  the
wheels  and  wheel  speed  sensors.  This  sensor  outputs
frequency pulse signals in proportion to the wheel speed.

｠

The pulse signals, which the wheel speed sensor creates, are
sent to ABS-ECU. ABS-ECU uses the frequency of the pulse
signals to determine the wheel speed.

DTC SET CONDITIONS
This diagnostic trouble code is set if any malfunction below is
found:

｠

When the brake fluid pressure is decreased for a long time.

｠

When the brake fluid pressure is held for a long time.

detection encoder

｠

Missing teeth of the wheel speed detection encoder

and C1042 are also set.

Q:Are DTC C1015, C101C, C101F, and C1042 also set?

YES:

 Carry out the diagnosis for the relevant diagnostic

trouble codes, and then go to Step 5.

NO:

 Go to Step 4.

STEP 4. Check whether the diagnostic trouble code is reset.

(1)

Erase the diagnostic trouble code.
