TC and CG Terminal Circuit

DESCRIPTION

Connecting terminals TC and CG of the DLC3 causes the ECU to display the DTC by flashing the ABS warning light.

INSPECTION PROCEDURE

NOTE: When replacing the ABS and TRACTION actuator assembly, perform zero point calibration (Programming and Relearning).

PROCEDURE

1. INSPECT 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:

NG -- CHECK HARNESS AND CONNECTOR (CG of DLC3 - BODY GROUND)
OK -- Continue to next step.
2. CHECK HARNESS AND CONNECTOR (ECM - TC of DLC3)

(a) Disconnect the ECM connector.
(b) Measure the resistance according to the value(s) in the table below.
Standard resistance:

NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.
3. CHECK HARNESS AND CONNECTOR (ECM - SKID CONTROL ECU)

(a) Disconnect the skid control ECU connector and the ECM connector.
(b) Measure the resistance according to the value(s) in the table below.
Standard resistance:

NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- REPLACE ABS AND TRACTION ACTUATOR ASSEMBLY
4. CHECK HARNESS AND CONNECTOR (CG of DLC3 - BODY GROUND)

(a) Measure the resistance according to the value(s) in the table below.
Standard resistance:

NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.
5. CHECK HARNESS AND CONNECTOR (ECM - TC of DLC3)

(a) Disconnect the ECM connector.
(b) Measure the resistance according to the value(s) in the table below.
Standard resistance:

NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.
6. CHECK HARNESS AND CONNECTOR (ECM - SKID CONTROL ECU)

(a) Disconnect the skid control ECU connector and the ECM connector.
(b) Measure the resistance according to the value(s) in the table below.
Standard resistance:

NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- REPLACE ABS AND TRACTION ACTUATOR ASSEMBLY
