A toothed ABS rotor generates a voltage pulse as it moves across the pickup
field of each ABS sensor. The amount of voltage generated at each wheel is determined by the clearance
between the ABS rotor teeth and the ABS sensor, and by the speed of rotation. Sends alternating current signals at frequencies which are proportional to the
rotation speeds of each wheel to the TCL/ASC electronic control unit
(TCL/ASC-ECU). The ABS hydraulic unit modulates the amount of braking force individually
applied to each wheel cylinder.
TCL/ASC DTC SET CONDITIONS The TCL/ASC-ECU monitors voltage fluctuation in each ABS sensor circuit. If the
ECU detects short or open circuit in the circuit, it will set a diagnostic trouble code. TROUBLESHOOTING HINTS (The most likely causes for these DTCs are to set are:)
Current trouble
Malfunction of the ABS sensor Damaged wiring harness or connector Malfunction of the hydraulic unit (integrated with TCL/ASC-ECU)
Past trouble
Carry out diagnosis with particular emphasis on connector(s) or wiring harness
in ABS sensor circuit. For diagnosis procedures, refer to HOW TO USE TROUBLESHOOTING/INSPECTION SERVICE POINTS
.
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

Q: Is the harness wire between TCL/ASC-ECU connector A-32 (terminal
6, 7) and ABS sensor < rear: LH > connector D-15 (terminal 1, 2)
damaged?
YES: Repair the wiring harness. Then go to Step 17.
NO: Go to Step 15.
STEP 15. Inspect the ABS sensor.
Check the ABS sensor relevant to the DTC code. For the applicable inspection
procedure, refer to WHEEL SPEED SENSOR .
When DTC code C1200 is set: Front right ABS sensor When DTC code C1205 is set: Front left ABS sensor

CIRCUIT OPERATION
A toothed ABS rotor generates a voltage pulse as it moves across the pickup
field of each ABS sensor. The amount of voltage generated at each wheel is determined by the clearance
CAUTION: 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.

between the ABS rotor teeth and the ABS sensor, and by the speed of rotation. Sends alternating current signals at frequencies which are proportional to the
rotation speeds of each wheel to the TCL/ASC electronic control unit
(TCL/ASC-ECU). The ABS hydraulic unit modulates the amount of braking force individually
applied to each wheel cylinder.
ABS DTC SET CONDITIONS The TCL/ASC-ECU monitors the signals from each ABS sensor while the vehicle
is being driven. If any faults below are found in these sensor signals, the ECU will
set the relevant diagnostic trouble code.
Missing sensor signal Sensor signal, which will not be created under normal operation Significant difference among the ABS sensor signals
TROUBLESHOOTING HINTS (The most likely causes for these DTCs are to set are:)
Current trouble
Malfunction of the ABS sensor or ABS rotor Damaged wiring harness or connector Malfunction of the hydraulic unit (integrated with TCL/ASC-ECU)
Past trouble

Q: Is the ABS sensor in good condition?
YES: Go to Step 6.
NO: Replace the ABS sensor. Then go to Step 16.
STEP 6. Check the wheel bearing for looseness.
DTC C1201 is set: Check the front right wheel bearing (Refer toWHEEL BEARING END PLAY CHECK
).
DTC C1206 is set: Check the front left wheel bearing (Refer to WHEEL BEARING END PLAY CHECK
).
DTC C1211 is set: Check the rear right wheel bearing (Refer to WHEEL BEARING END PLAY CHECK
).
DTC C1216 is set: Check the rear left wheel bearing (Refer to WHEEL BEARING END PLAY CHECK
).
Q: Is the wheel bearing end play within the standard value?
YES: Go to Step 7.
NO (front bearing end play is not within the standard value): Replace
the front hub assembly (Refer to FRONT AXLE HUB ASSEMBLY
, ).
Then go to Step 16.
NO (rear bearing end play is not within the standard value): Replace
the rear hub assembly (Refer to REAR AXLE
). Then go to Step 16.
STEP 7. Check the ABS rotor.
Check the ABS rotor, which DTC code indicates, for foreign material or
deformation.
DTC C1201 is set: Front right ABS sensor DTC C1206 is set: Front left ABS sensor
NOTE: If the wheel bearing is loose, the gap between the ABS
sensor and rotor may become excessive. Check the
wheel bearing, which DTC code indicates, for
looseness.

6. Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is DTC C1394 set?
YES: Initialize the steering sensor (Refer to STEERING WHEEL
SENSOR
).
NO: The procedure is complete.
DTC C1395: INCOMP. BRAKE FLUID FILLING TCL/ASC DTC SET CONDITIONS This DTC is set if air-bleeding has not been performed. TROUBLESHOOTING HINTS (The most likely causes for these DTCs are to set are:)
The CAN bus line is defective. Malfunction of the hydraulic unit (integrated with TCL/ASC-ECU)

STEP 1. Using scan tool MB991958, diagnose the CAN bus line. CAUTION: 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.
CAUTION: Whenever the ECU is replaced, ensure that the CAN
bus lines are normal.
