DTC C123C: Abnormality in G and yaw rate sensor (lateral G and yaw rate sensor)

M13506100060USA0000010000

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).

ACTIVE SKID CONTROL SYSTEM (ASC)

35C-135

DIAGNOSIS

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.

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

The output value of lateral G and yaw rate sensor is abnormal.

When abnormality is detected by comparing the value output
from the lateral G and yaw rate sensor with the one from the
steering wheel sensor and wheel speed sensor

PROBABLE CAUSES

Improper installation of the G and yaw rate sensor

G and yaw rate sensor malfunction

Steering wheel sensor malfunction

Malfunction of wheel speed sensor

ASC-ECU malfunction

External noise interference

DIAGNOSIS

Required Special Tools:

MB991958: Scan Tool (M.U.T.-III Sub Assembly)

MB991824: Vehicle Communication Interface (V.C.I.)

MB991827: M.U.T.-III USB Cable

MB991910: M.U.T.-III Main Harness A

STEP 1. M.U.T.-III CAN bus diagnostics
Use scan tool to diagnose the CAN bus lines.

Q:Is the check result normal?

YES:

 Go to Step 3.

NO:

 Repair the CAN bus lines. (Refer to GROUP 54D - CAN

Bus Diagnostics table P.54D-17.) On completion, go to
Step 2.

STEP 2. Diagnostic trouble code recheck after resetting
CAN bus lines

Q:Is DTC C123C set?

YES:

 Go to Step 3.

NO:

 The procedure is complete.

STEP 3. Check the wheel speed sensor-related diagnostic
trouble code.
Use scan tool to check whether the wheel speed sensor-related
or steering wheel sensor-related diagnostic trouble code is set
or not.

Q:Is any DTC set?

35C-136

ACTIVE SKID CONTROL SYSTEM (ASC)

DIAGNOSIS

YES:

 Troubleshoot for the relevant diagnostic trouble

code. (Refer to P.35C-11.)

NO:

 Go to Step 4.

STEP 4. G and yaw rate sensor installation check
Check that the G and yaw rate sensor is installed correctly.

Q:Is the check result normal?

YES:

 Go to Step 5.

NO:

 Reinstall the G and yaw rate sensor correctly.

STEP 5. M.U.T.-III data list
Check the following service data.

Item 08: Lateral G-sensor

Item 12: Yaw rate sensor

Q:Is the check result normal?

YES:

 Go to Step 6.

NO:

 Replace the G and yaw rate sensor, and then go to

Step 7.

STEP 6. M.U.T.-III data list
Check the following service data.

Item 11: Steering angle sensor

Q:Is the check result normal?

YES:

 Go to Step 7.

NO:

 Replace the steering wheel sensor, and then go to

Step 7.

STEP 7. Check whether the diagnostic trouble code is reset.

Q:Is DTC C123C set?

YES:

 Replace the ASC-ECU.

NO:

 The procedure is complete.

DTC C2204: Internal abnormality in G and yaw rate sensor (lateral G and yaw rate
sensor)

M13506100061USA0000010000

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.

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

ACTIVE SKID CONTROL SYSTEM (ASC)

35C-137

DIAGNOSIS

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

When the output value of the G and yaw rate sensor is not
within the standard value range

NOTE: 

This diagnostic trouble code may be set when G and

yaw rate sensor is put on the turntable turning at high
speed.

PROBABLE CAUSES

Improper installation of the G and yaw rate sensor

Damaged wiring harness and connectors

G and yaw rate sensor malfunction

ASC-ECU malfunction

DIAGNOSIS

Required Special Tools:

MB991958: Scan Tool (M.U.T.-III Sub Assembly)

MB991824: Vehicle Communication Interface (V.C.I.)
