YES: Repair or replace the damaged component(s). Then go to Step 16.
NO: Open or short circuit may be present in the rear left ABS sensor
circuit. Repair the wiring harness between TCL/ASC-ECU connector A-
32 (terminals 6 and 7) and rear left ABS sensor D-10 (terminals 1 and 2).
Then go to Step 16
.
STEP 15. Recheck for diagnostic trouble code.
Check again if the DTC is set.
1. Turn the ignition switch to the "ON" position.

CIRCUIT OPERATION
CAUTION: If there is any problem in the CAN bus lines, an
incorrect dia
gnostic trouble code ma
y be set. Prior to
this diagnosis, diagnose the CAN bus lines.

The TCL/ASC-ECU gathers information regarding lateral and longitudinal
accelerations and yaw rate, through the CAN bus line from the G and yaw rate
sensor. TCL/ASC DTC SET CONDITIONS The TCL/ASC-ECU activates the G and yaw rate sensor via a CAN bus line in
order to diagnose the sensor whenever the ignition switch is turned on. If the G and
yaw rate sensor does not respond to this request, this DTC will be set. TROUBLESHOOTING HINTS (The most likely causes for these DTC are to set are:)
Current trouble
The CAN bus line is defective. Damaged connector(s) The G and yaw rate sensor is defective. The TCL/ASC-ECU is defective.
Past trouble Carry out diagnosis with particular emphasis on connector(s) or wiring harness
between the TCL/ASC-ECU and the G and yaw rate sensor. For diagnosis
procedures, refer to HOW TO COPE WITH INTERMITTENT MALFUNCTIONS
.
DIAGNOSIS Required Special Tools:
MB991958: Scan Tool (MUT-III Sub Assembly)
MB991824: Vehicle Communication Interface (V.C.I.) MB991827: MUT-III USB Cable MB991910: MUT-III Main Harness A
STEP 1. Using scan tool MB991958, diagnose the CAN bus line.
CAUTION: To prevent damage to scan tool MB991958,

6. Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is DTC C1223 set?
YES: Go to Step 3.
NO: The procedure is complete.
STEP 3. Using scan tool MB991958, check data list items 30: Straight G
sensor, 31: Lateral G sensor and 33: Yaw rate G sensor.
1. Connect scan tool MB991958 to the data link connec
tor. CAUTION: To prevent damage to scan tool MB991958,
always turn the ignition switch to the
"LOCK" (OFF) position before connecting or
disconnecting scan tool MB991958.

2. Turn the ignition switch to the "ON" position.
3. Set scan tool MB991958 to data reading mode for item 30: Straight G
sensor, item 31: Lateral G sensor and item 33: Yaw rate G sensor.
Item 30: Straight G sensor
Acceleration should change within the range of -9.8 -9.8 m/s
2
during running.
Item 31: Lateral G sensor
Acceleration should change within the range of -9.8 -9.8 m/s
2
during running.
Item 33: Yaw late sensor
Angular velocity should change within the range of -50 -50 deg/s
during running.
Q: Does the G and yaw rate sensor output correct acceleration and
angular velocity?
YES: Go to Step 5.
NO: Go to Step 4.
STEP 4. Recheck for diagnostic trouble code after the G and yaw rate
sensor is replaced.
Replace the G and yaw rate sensor, and check whether DTC C1223 is reset.
1. Replace the G and yaw rate sensor.
2. Connect scan tool MB991958 to the data link connec
tor. CAUTION: To prevent damage to scan tool MB991958,
always turn the ignition switch to the
"LOCK" (OFF) position before connecting or
disconnecting scan tool MB991958.
