DESCRIPTION
DTC output mode is set by connecting terminals TC and CG of the DLC3.
The DTCs are displayed by the blinking pattern of the ABS warning light.
WIRING DIAGRAM
HINT: When warning lights continue to blink, a ground short in the wiring of terminal TC of the DLC3 or an internal ground short in one or more ECU is suspected.
INSPECTION PROCEDURE
1 INSPECT DLC3 (BETWEEN TC of DLC3 AND CG of DLC3)
(a) Turn the ignition switch to the ON position.
(b) Measure the voltage according to the value(s) in the table below.
Standard voltage
2 CHECK HARNESS AND CONNECTOR (BETWEEN SKID CONTROL ECU AND TC of DLC3)
(a) Turn the ignition switch off.
(b) Disconnect the skid control ECU connector.
(c) Measure the resistance according to the value(s) in the table below.
Standard resistance
REPLACE BRAKE ACTUATOR ASSEMBLY
3 CHECK HARNESS AND CONNECTOR (BETWEEN CG of DLC3 AND BODY GROUND)
(a) Turn the ignition switch off.
(b) Measure the resistance according to the value(s) in the table below.
