DTC TABLE OF ABS

DTC No.
None Normal
Wheel speed sensor related malfunction
25
Incorrect tire size, poor tire pressure, deformed wheel, wheel spinning,
(C1625)
incorrect tooth count, interference at one or more wheels, permanent
bad signal, etc.
ABS motor malfunction
35
Motor relay circuit open or short, broken fuse for motor relay, pump
(C1635)
motor circuit open or short, faulty motor relay, faulty ABS motor, faulty
ABS control unit, etc.
Wheel speed sensor signal malfunction (F) *2
41
Too great air gap, worn or missing teeth, noise, interference between
(C1641)
lines, loose contact in wheel speed sensor connector, wheel speed sen-
sor not securely fastened, input amplifier in ABS control unit failure, etc.
Wheel speed sensor circuit open (F) *2
42
Wheel speed sensor circuit open or short, loosen contact in wheel
(C1642)
speed sensor connector, input amplifier in ABS control unit failure, etc.
Wheel speed sensor signal malfunction (R) *2
44
Too great air gap, worn or missing teeth, noise, interference between
(C1644)
lines, loose contact in wheel speed sensor connector, wheel speed sen-
sor not securely fastened, input amplifier in ABS control unit failure, etc.
Wheel speed sensor circuit open (R) *2
45
Wheel speed sensor circuit open or short, loosen contact in wheel
(C1645)
speed sensor connector, input amplifier in ABS control unit failure, etc.
Supply voltage (Increased)
47
(C1647)
Faulty regulator/rectifier, faulty battery, faulty wire harness, etc.
Supply voltage (Decreased)
48
Faulty generator, faulty regulator/rectifier, faulty battery, faulty wire har-
(C1648)
ness, etc.
ABS control unit malfunction
55
(C1655)
Faulty ABS control unit
ABS solenoid malfunction
61
Valve relay circuit open or short, broken fuse for valve relay, faulty valve
(C1661)
relay, interruption of valve, failure output from ABS control unit, etc.
*1 It goes off after running at more than 5 km/h (3.1 mile/h).
*2 The wheel speed sensor lead wire is connected to the ABS control unit, but a short-circuit or faulty conti-
nuity inside the ABS control unit caused this DTC to appear, therefore, the ABS control unit/HU assembly
must be replaced. An insufficient wheel speed sensor output voltage is the cause of a malfunction in
which the ABS is activated even if the brakes are not suddenly applied. If this occurs frequently even
though the wheel speed sensor is operating correctly, the ABS control unit/HU assembly should be
replaced.
*3 When the voltage resumes the normal level, the ABS indicator light will go off.
*4 There are times that the ABS indicator light does not light up.
%
When disconnecting couplers and turning the ignition switch to ON, disconnect the ABS con-
trol unit coupler in order to prevent a DTC from being stored. Each time a resistance is mea-
sured, the ignition switch should be set to OFF.
