ABS Warning Light Circuit
CIRCUIT DESCRIPTION
If the ECU detects trouble, the ABS warning light lights up and ABS control is prohibited at the same time.
At this time, the ECU records a DTC in memory.
Connecting terminals Tc and E
1 of the DLC1 makes the ABS warning light blink and output the DTC.

INSPECTION PROCEDURE
1 Is DTC output?
Check the DTC on page DI-212.
YES Repair circuit indicated by the code output.
NO
2 Is normal code displayed?
YES Check for short circuit in harness and connec-
tor between DLC1 or DLC2 and ABS ECU (See
page IN-30).
NO
3 Is ABS warning light off?
YES Check open and short circuit of the harness and
connector in the Tc circuit between ABS ECU
and DLC2 or DLC1.

Tc Terminal Circuit
CIRCUIT DESCRIPTION
Connecting between terminals Tc and E1 of the DLC1 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.
CHECK:
(a) Turn the ignition switch ON.
(b) Measure the voltage between terminals Tc and E
1 of
DLC1 or terminal Tc of DLC2 and body ground.
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.

DIAGNOSTIC TROUBLE CODE CHART
HINT:
Using SST 09843-18020, connect the terminals Tc and E1.
If any abnormality is found when inspecting parts, inspect the ECU.
If a malfunction code is displayed during the DTC check, check the circuit listed under the code. For
details of each code, refer to the page under respective ºDTC No.º in the DTC chart.

*: As the DTC cannot only be erased by replacing parts, do either of the following operations.
(1) Clear DTC (See page DI-212).
(2) At a vehicle speed of 20 km/h (12 mph), drive the vehicle for 30 sec. or more.
