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
.

6. Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is DTC C1200, C1205, C1210 or C1215 set?
YES: Replace the hydraulic unit (integrated with ABS-ECU). Then go to
Step 17.
NO: It can be assumed that this malfunction is intermittent. Refer to
HOW TO COPE WITH INTERMITTENT MALFUNCTIONS
.
STEP 17. Recheck for diagnostic trouble code.
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 set.

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
).
DIAGNOSIS

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 DTC C1211 is set: Rear right ABS sensor DTC C1216 is set: Rear left ABS sensor
Q: Is the ABS rotor in good condition?
YES: Go to Step 8.
NO (front bearing end play is not within the standard value): If the
ABS rotor is contaminated with foreign material, clean it. If the driveshaft
is deformed, replace it (Refer to DRIVE SHAFT ASSEMBLY
, ). Then
go to Step 16 .
NO (rear bearing end play is not within the standard value < FWD >):
If the ABS rotor is contaminated with foreign material, clean it. If the
ABS rotor is deformed, replace it (Refer to REAR AXLE HUB
ASSEMBLY
, ). Then go to Step 16 .
NO (rear bearing end play is not within the standard value < AWD
>): If the ABS rotor is contaminated with foreign material, clean it. If the
BJ assembly is deformed, replace it (Refer to DRIVE SHAFT
ASSEMBLY
). Then go to Step 16 .
STEP 8. Measure the voltage at ABS-ECU connector A-02.
1. Disconnect the connector A-02, and connect special tool ABS Check
Harness (MB991970) to the wiring harness-side connector.
NOTE: Do not connect special tool ABS Check Harness
(MB991970) to the ABS-ECU.

2. Turn the ignition switch to the "ON" position.
3. Measure the voltage between the relevant signal and ground terminals in
the ABS sensor circuit and body ground. It should be less than 1V.
DTC C1201 is set: Between signal terminal 9 and body ground, and
between ground terminal 10 and body ground DTC C1206 is set: Between signal terminal 26 and body ground, and
between ground terminal 16 and body ground DTC C1211 is set: Between signal terminal 11 and body ground, and
between ground terminal 17 and body ground DTC C1216 is set: Between signal terminal 28 and body ground, and
between ground terminal 27 and body ground
Q: Does the voltage measure 1 V or less?
YES: Go to Step 9.
NO (When the voltage between terminal 9 or 10 - and body ground
measures more than 1 V): Go to Step 11 .
NO (When the voltage between terminal 26 or 16 - and body ground
measures more than 1 V): Go to Step 12 .
NO (When the voltage between terminal 11 or 17 - and body ground
measures more than 1 V): Go to Step 13 .
NO (When the voltage between terminal 28 or 27 - and body ground
measures more than 1 V): Go to Step 14 .
STEP 9. Measure the resistance at ABS-ECU connector A-02.
1. Disconnect the connector A-02, and connect special tool ABS Check
Harness (MB991970) to the wiring harness-side connector.
2. Measure the resistance between the relevant signal and ground terminals
in the ABS sensor circuit and body ground. OK if there is no continuity. DTC C1201 is set: Between signal terminal 9 and bo
dy ground, and NOTE: Do not connect special tool ABS Check Harness
(MB991970) to the ABS-ECU.
