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.

PRE±CHECK
1. DIAGNOSIS SYSTEM
(a) Check the indicator.
When the ignition switch is turned ON, check that the ABS
warning light goes on for 2 seconds.
HINT:
If the indicator check result is not normal, proceed to trouble-
shooting for the ABS warning light circuit (See page DI±565).
(b) Check the DTC.
(1) Using SST, connect terminals Tc and E
1 of DLC2 or
DLC1.
SST 09843 ± 18020
(2) Turn the ignition switch ON.
(3) Read the DTC from the ABS warning light on the
combination meter.
HINT:

If no code appears, inspect the diagnostic circuit or ABS
warning light circuit (See page DI±567 or DI±565).

As an example, the blinking patterns for normal code and
codes 11 and 21 are shown on the left.
(4) Codes are explained in the code table on page
DI±542.
(5) After completing the check, disconnect terminals Tc
and E
1, and turn off the display.
If 2 or more malfunctions are indicated at the same time the low-
est numbered DTC will be displayed 1st.
(c) Using TOYOTA hand±held tester, check the DTC.
(1) Hook up the TOYOTA hand±held tester to the
DLC2.
(2) Read the DTC by following the prompts on the tes-
ter screen.
Please refer to the TOYOTA hand±held tester oper-
ator 's manual for further details.

(d) Clear the DTC.
(1) Using SST, connect terminals Tc and E
1 of DLC2 or
DLC1.
SST 09843 ± 18020
(2) Turn the ignition switch ON.
(3) Clear the DTC stored in ECU by depressing the
brake pedal 8 or more times within 3 seconds.
(4) Check that the warning light shows the normal
code.
(5) Remove the SST from the terminals of DLC2 or
DLC1.
SST 09843 ± 18020
HINT:
Cancellation cannot be done by removing the battery cable or
ECU±B fuse.
2. SPEED SENSOR SIGNAL
(a) Check the speed sensor signal.
(1) When the ignition switch is turned ON, check that
the ABS warning light goes on for 2 seconds.
(2) Turn the ignition switch OFF.
(3) Using SST, connect terminals Ts and E
1 of DLC1.
SST 09843 ± 18020
(4) Start the engine.
(5) Check that the ABS warning light blinks.
HINT:
If the ABS warning light does not blink, inspect the ABS warning
light circuit (See page DI±565).
(6) Drive vehicle straight forward.
HINT:
Drive vehicle at 45 ± 55 km/h (28 ± 34 mph) for several seconds.
If the brake is applied during the check, the check routine must
be started again.
(7) Stop the vehicle.
(8) Turn the ignition switch OFF.
(9) Disconnect the SST from terminals Ts and E
1 and,
connect the SST to terminals Tc and E
1 of DLC1.
SST 09843 ± 18020
(10) Turn the ignition switch ON.
(11) Read the number of blinks of the ABS warning light.
