TC and CG Terminal Circuit (from 12/2010)
BRAKE CONTROL: VEHICLE STABILITY CONTROL SYSTEM: TC and CG Terminal Circuit
- TC and CG Terminal Circuit
DESCRIPTION
Connecting terminals TC and CG of the DLC3 causes the ECU to display the DTC by blinking the ABS warning light.
WIRING DIAGRAM
INSPECTION PROCEDURE
NOTICE:
When replacing the ABS & TRACTION actuator assembly, perform zero point calibration Calibration (from 12/2010).
PROCEDURE
1. INSPECT DLC3 (TC AND CG TERMINAL)
(a) Turn the ignition switch on (IG).
(b) Measure the voltage according to the value(s) in the table below.
Standard voltage:
(c) Measure the resistance according to the value(s) in the table below.
Standard resistance:
NG -- CHECK HARNESS AND CONNECTOR (ECM TO DLC3)
OK -- Continue to next step.
2. CHECK HARNESS AND CONNECTOR (ECM TO DLC3)
(a) Disconnect the ECM connector.
(b) Measure the resistance according to the value(s) in the table below.
Standard resistance:
(c) Measure the resistance according to the value(s) in the table below.
Standard resistance:
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR (TC TERMINAL CIRCUIT)
OK -- Continue to next step.
3. CHECK CAN COMMUNICATION SYSTEM
(a) Check if the CAN communication system DTC is output Reading and Clearing Diagnostic Trouble Codes.
Result:
HINT
If troubleshooting has been carried out according to the Problem Symptoms Table, refer back to the table and proceed to the next step before replacing the part Problem Symptoms Table (from 12/2010).
B -- REPAIR CIRCUIT INDICATED BY OUTPUT CODE
A -- REPLACE ABS & TRACTION ACTUATOR ASSEMBLY
4. CHECK HARNESS AND CONNECTOR (ECM TO DLC3)
(a) Disconnect the ECM connector.
(b) Measure the resistance according to the value(s) in the table below.
Standard resistance:
(c) Measure the resistance according to the value(s) in the table below.
Standard resistance:
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR (TC CIRCUIT)
OK -- Continue to next step.
5. CHECK HARNESS AND CONNECTOR (DLC3 TO BODY GROUND)
(a) Measure the resistance according to the value(s) in the table below.
Standard resistance:
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR (GND CIRCUIT)
OK -- Continue to next step.
6. CHECK ECM (DLC3 (TC) INPUT)
(a) Using SST, connect the terminals TC and CG of the DLC3.
SST : 09843-18040
(b) Check that the engine warning light is blinking.
Result:
B -- REPLACE ECM
A -- Continue to next step.
7. CHECK CAN COMMUNICATION SYSTEM
(a) Check if the CAN communication system DTC is output Reading and Clearing Diagnostic Trouble Codes.
Result:
HINT
If troubleshooting has been carried out according to the Problem Symptoms Table, refer back to the table and proceed to the next step before replacing the part Problem Symptoms Table (from 12/2010).
B -- REPAIR CIRCUIT INDICATED BY OUTPUT CODE
A -- REPLACE ABS & TRACTION ACTUATOR ASSEMBLY
