DTCC0278 / 11, C0279 / 12ABS Solenoid Relay Circuit
CIRCUIT DESCRIPTION
This relay supplies power to each ABS solenoid. After the ignition switch is turned ON, if the initial check is
OK, the relay goes on.
DTC No.DTC Detecting ConditionTrouble Area
C0278 / 11
Conditions 1. and 2. continue for 0.2 sec. or more:
1. ECU terminal IG1 voltage is 9.5 V to 17.0 V and the
solenoid relay is ON, however, the contact point of the
solenoid relay is OFF.
2. With solenoid relay ON, ECU terminal IG1 voltage be-
comes 9.5 V or less and the contact point of the sole-
noid relay does not become ON.

ABS solenoid relay

ABS solenoid relay circuit
C0279 / 12
Immediately after ECU terminal IG1 becomes ON, and
solenoid relay is OFF, however, when the condition that
the solenoid relay due to the contact point is ON continues
for 0.2 sec. or more.
WIRING DIAGRAM
Refer to DTC C0226/21 on page DI-528.
INSPECTION PROCEDURE
HINT:
Start the inspection from step 1 in case of using the hand-held tester and start from step 2 in case of not
using the hand-held tester.
1 Check ABS solenoid relay operation.
PREPARATION:
(a) Connect the hand-held tester to the DLC3.
(b) Turn the ignition switch ON and push the hand-held tester main switch ON.
(c) Select the ACTIVE TEST mode on the hand-held tester.
CHECK:
Check the operation sound of the ABS solenoid relay when operating it with the hand-held tester.
OK:
The operation sound of the ABS solenoid relay should be heard.
OK Go to step 6.

skid control ECU.
CHECK:
Check continuity between terminal 3 of the ABS solenoid relay
and terminal AST of the skid control ECU.
OK:
Continuity
HINT:
There is resistance of 33 ± 3 W between terminals 4 of connec-
tor A43 and terminal 1 of connector A44.
NG Repair or replace harness, connector or hy-
draulic brake booster.
OK
5 Check for open and short circuit in harness and connector between ABS sole-
noid relay and skid control ECU (See page IN-36).
NG Repair or replace harness or connector.
OK
If the same code is still output after the DTC is deleted, check the contact condition of each con-
nection. If the connections are normal, the ECU may be defective.
