STEP 13. Check ABS-ECU connector A-02, intermediate
connector C-25 and wheel speed sensor <Rear: RH>
connector F-04 for loose, corroded or damaged terminals,
or terminals pushed back in the connector.
Q: Are ABS-ECU connector A-02, intermediate connector
C-25 and wheel speed sensor <Rear: RH> connector
F-04 damaged?
YES : Repair or replace the damaged component(s). Refer
to GROUP 00E, Harness Connector Inspection
NO : Open or short circuit may be present in the rear right
wheel speed sensor circuit. Repair the wiring harness
between ABS-ECU connector A-02 (terminals 11 and
17) and rear right wheel speed sensor F-04 (terminals
1 and 2).Then go to Step 16.

STEP 14. Check ABS-ECU connector A-02, intermediate
connector C-25 and wheel speed sensor <rear: LH>
connector F-07 for loose, corroded or damaged terminals,
or terminals pushed back in the connector.
Q: Are ABS-ECU connector A-02, intermediate connector

damaged?
YES : Repair or replace the damaged component(s). Refer
to GROUP 00E, Harness Connector Inspection
NO : Open or short circuit may be present in the rear left
wheel speed sensor circuit. Repair the wiring harness
between ABS-ECU connector A-02 (terminals 27 and
28) and rear left wheel speed sensor F-07 (terminals
2 and 1).Then go to Step 16.

STEP 15. 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 set.
(6) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is DTC C1201, C1206, C1211 or C1216 set?
YES : Replace the hydraulic unit (integrated with
ABS-ECU). Then go to Step 16.
NO : It can be assumed that this malfunction is intermittent.
Refer to GROUP 00, How to Use
Troubleshooting/Inspection Service Points
− How to
Cope with Intermittent Malfunction
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 set.
(6) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is DTC C1201, C1206, C1211 or C1216 set?
YES : Go to Step 1.

DTC C1226/C1231/C1236/C1241/C1246/C1251/C1256/C1261: ABS Solenoid Valve
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.
.
CIRCUIT OPERATION
• The ABS-ECU contains the power supply circuit
(terminal 1) for the solenoid valve. The solenoid
valve is energized by the valve relay, which is
integrated in the ABS-ECU.
• The valve relay, which is integrated in the
ABS-ECU, is always energizing the solenoid
valve unless the initial check is in progress when
the ignition switch is turned on.
• The ABS-ECU activates the solenoid valve by
turning on its driving transistor.
