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

When DTC code C1210 is set: Rear right ABS sensor When DTC code C1215 is set: Rear left ABS sensor
Q: Is the ABS sensor damaged?
YES: Replace the ABS sensor. Then go to Step 17.
NO: It can be assumed that this malfunction is intermittent. Refer to
HOW TO COPE WITH INTERMITTENT MALFUNCTIONS
.
STEP 16. Recheck for diagnostic trouble code.
Check again if the DTC is set.
1. Turn the ignition switch to the "ON" position.
2. Erase the DTC.
3. Turn the ignition switch to the "LOCK" (OFF) position.
4. Turn the ignition switch to the "ON" position.
5. Check if the DTC is reset.

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
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
