2 Check ABS solenoid relay.
PREPARATION:
Remove ABS solenoid relay from Engine Room R/B No. 3.
CHECK:
Check continuity between each terminal of ABS solenoid relay.
OK:
Terminals 4 and 6Continuity (Reference value 80 W)
Terminals 2 and 3Continuity
Terminals 1 and 3Open
CHECK:
(a) Apply battery positive voltage between terminals 4 and 6.
(b) Check continuity between each terminal of ABS solenoid
relay.
OK:
Terminals 2 and 3Open
Terminals 1 and 3Continuity
CHECK:
Connect the
test lead to terminal 5 and the  lead to terminal
3. Check continuity between the terminals.
OK:
Continuity
If there is no continuity, connect the  test lead to terminal 5
and the
lead to terminal 3. Recheck continuity between ter-
minals.
NG Replace ABS solenoid relay.
OK
Check for open circuit in harness and connector between DLC1, ABS solenoid relay and body
ground (See page IN±31).

3 Is DTC output?
Check DTC on page DI±493.
YES Repair circuit indicated by the code output.
NO
4 Does ABS warning light go off if short pin is removed?
NO Check for short circuit in harness and connec-
tor between ABS warning light, DLC1 and ABS
ECU (See page IN±31).
YES
5 Check ABS solenoid relay (See step 2).
NG Replace ABS solenoid relay.
OK
Check for short circuit in harness and connector between DLC1 and ABS solenoid relay
(See page IN±31).

Tc Terminal Circuit
CIRCUIT DESCRIPTION
Connecting between terminals Tc and E1 of the DLC1 or the DLC2 causes the ECU to display the DTC by
flashing the ABS warning light.
WIRING DIAGRAM
INSPECTION PROCEDURE
1 Check voltage between terminals Tc and E1 of DLC2 or DLC1.
CHECK:
(a) Turn the ignition switch ON.
(b) Measure voltage between terminals Tc and E
1 of DLC2 or
DLC1.
OK:
Voltage: 10 ± 14 V
OK If ABS warning light does not blink even after Tc
and E
1 are connected, the ECU may be defec-
tive.

Ts Terminal Circuit
CIRCUIT DESCRIPTION
The sensor check circuit detects abnormalities in the speed sensor signal which cannot be detected with
the DTC check.
Connecting terminals Ts and E
1 of the DLC1 in the engine compartment starts the check.

INSPECTION PROCEDURE
1 Check voltage between terminals Ts and E1 of DLC1.
CHECK:
(a) Turn the ignition switch ON.
(b) Measure voltage between terminals Ts and E
1 of DLC1.
OK:
Voltage: 10 ± 14 V
OK If ABS warning light does not blink even after Ts
