Q: Is the harness wire between ABS-ECU connector A-02 (terminal 28,
27) 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 INSPECTION
.
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 ri
ght 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.

6. Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is DTC C1200, C1205, C1210 or C1215 set?
YES: Repeat the troubleshooting from Step 1 .
NO: The procedure is complete.

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
to HOW TO USE TROUBLESHOOTING/ INSPECTION SERVIC
