DTC C2206: Re-execution of variant coding

M13506100057USA0000010000

｠

If the diagnostic trouble code C2206 is set in ASC-ECU,
always diagnose the CAN bus line. If there is any fault in
the CAN bus lines, an incorrect diagnostic trouble code
may be set. In this case, the set diagnostic trouble code
is not highly reliable.

｠

Before replacing the ECU, ensure that the communication
circuit is normal.

｠

When the diagnostic trouble code C2206 is set in ASC-
ECU,  the  diagnostic  trouble  code  may  also  be  set  in
ETACS-ECU. When the diagnostic trouble code is set in
ETACS-ECU,  carry  out  the  diagnosis  of  the  diagnostic
trouble code for ETACS-ECU first.

CIRCUIT OPERATION
ASC-ECU receives the vehicle information stored in the ETACS-
ECU via CAN bus lines.

DTC SET CONDITIONS
ASC-ECU communicates with ETACS-ECU via CAN bus lines.
This  diagnostic  trouble  code  is  set  if  the  vehicle  information
stored  in  ETACS-ECU  varies  from  the  one  stored  when  the
ignition switch was last turned on.

PROBABLE CAUSES

｠

ETACS-ECU  or  ASC-ECU  which  was  equipped  with  other
vehicle is used.

｠

Malfunction of ETACS-ECU

｠

ASC-ECU malfunction

｠

External noise interference

NO:

 The procedure is complete.

STEP 5. Check whether the diagnostic trouble code is reset.

Q:Is DTC C2206 set?

YES:

 Replace ETACS-ECU. Go to Step 6.

NO:

 The procedure is complete.

STEP 6. Check whether the diagnostic trouble code is reset.

Q:Is DTC C2206 set?

YES:

 Return to Step 1.

NO:

 The procedure is complete.

DTC C1210: Abnormality in G and yaw rate sensor (longitudinal G sensor)

M13506100058USA0000010000

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

｠

ASC-ECU supplies power to the G and yaw rate sensor at the
terminal No. 1.

｠

The G and yaw rate sensor outputs the signal to ASC-ECU via
the CAN bus lines.

35C-132

ACTIVE SKID CONTROL SYSTEM (ASC)

DIAGNOSIS

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

｠

When  the  output  value  of  the  longitudinal  G-sensor  is
abnormal

｠

When abnormality in longitudinal G-sensor is detected by the
self-diagnosis of the G and yaw rate sensor

PROBABLE CAUSES

｠

G and yaw rate sensor malfunction

｠

ASC-ECU malfunction

｠

External noise interference
