CIRCUIT OPERATION
A toothed ABS rotor

p
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.

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 ABS electronic control unit (ABS-ECU). The ABS hydraulic unit modulates the amount of braking force individually
applied to each wheel cylinder.
ABS DTC SET CONDITIONS The ABS-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 ABS-ECU)
Past trouble
Carry out diagnosis with particular emphasis o connector(s) or wiring harness
in ABS sensor circuit. For diagnosis procedures, refer to (Refer to HOW TO USE TROUBLESHOOTING/ INSPECTION SERVIC
).
PAST TROUBLE For diagnosis procedures, refer to "HOW TO TREAT PAST TROUBLE
" (Refer

Q: Is DTC C1200, C1205, C1210 or C1215 set?
YES: Carry out diagnosis relevant to DTC C1200, C1205, C1210 or
C1215 (Refer to DIAGNOSTIC TROUBLE CODE PROCEDURES
).
NO: Go to Step 4.
STEP 4. Check the installation condition of the ABS sensors.
For the ABS sensor, which the DTC code indicates, check whether the sensor
or its mounting bolts are loosened.
DTC C1201 is set: Front right ABS sensor DTC C1206 is set: Front left ABS sensor DTC C1211 is set: Rear right ABS sensor DTC C1216 is set: Rear left ABS sensor
Q: Is the ABS sensor installed correctly?
YES: Go to Step 5.
NO: Reinstall the ABS sensor correctly. Then go to Step 16 .
STEP 5 Check the ABS sensor after it is removed from the vehicle.
Check the ABS sensor, which the DTC code indicates (Refer to
INSPECTION
).
DTC C1201 is set: Front right ABS sensor DTC C1206 is set: Front left ABS sensor DTC C1211 is set: Rear right ABS sensor DTC C1216 is set: Rear left ABS sensor

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 to WHEEL 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 front right wheel bearing (WHEEL BEARING END PLAY CHECK
). < AWD > Refer to WHEEL
BEARING END PLAY CHECK
).
DTC C1216 is set: Check the rear left wheel bearing (< FWD > Refer to
WHEEL BEARING END PLAY CHECK
). < AWD > Refer to
WHEEL BEARING END PLAY CHECK ).
