TS and CG Terminal Circuit

SUSPENSION CONTROL: ADAPTIVE VARIABLE SUSPENSION SYSTEM: TS and CG Terminal Circuit
- TS and CG Terminal Circuit

DESCRIPTION

The signal check circuit detects any trouble in the sensor or switch signal which cannot be detected by the DTC check.

Connecting terminals TS and CG of the DLC3 starts the check.

NOTICE:
When replacing the absorber control ECU, check the acceleration sensor assembly signal after replacement Adaptive Variable Suspension System.

Check the condition of each related circuit connector before troubleshooting Electronic Circuit Inspection Procedure.

PROCEDURE

1. INSPECT TERMINAL VOLTAGE (DLC3 TS TERMINAL)

(a) Turn the engine switch on (IG).





(b) Measure the voltage according to the value(s) in the table below.

Voltage:





(c) Turn the engine switch off.

(d) Measure the resistance according to the value(s) in the table below.

Resistance:





NG -- CHECK HARNESS AND CONNECTOR (SKID CONTROL ECU TO DLC3)
OK -- Continue to next step.

2. CHECK HARNESS AND CONNECTOR (SKID CONTROL ECU TO DLC3)

(a) Disconnect the skid control ECU connector.





(b) Measure the resistance according to the value(s) in the table below.

Resistance (for 1UR-FSE):





Resistance (for 2GR-FSE):





NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR (TS TERMINAL CIRCUIT)
OK -- Continue to next step.

3. CHECK CAN COMMUNICATION SYSTEM

(a) Check if the CAN communication system DTC is output Adaptive Variable Suspension System.

Result:





C -- REPAIR CIRCUIT INDICATED BY OUTPUT CODE

B -- PROCEED TO NEXT CIRCUIT INSPECTION SHOWN IN PROBLEM SYMPTOMS TABLE

A -- REPLACE ABSORBER CONTROL ECU

4. CHECK HARNESS AND CONNECTOR (SKID CONTROL ECU TO DLC3)

(a) Disconnect the skid control ECU connector.





(b) Measure the resistance according to the value(s) in the table below.

Resistance (for 1UR-FSE):





Resistance (for 2GR-FSE):





NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR (TS TERMINAL 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.





Resistance:





NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR (GND CIRCUIT)
OK -- Continue to next step.

6. CHECK ECM (DLC3 TS INPUT)

(a) Using the SST, connect the terminals TS and CG of the DLC3.





SST : 09843-18040

(b) Check that the engine, ABS and VSC warning lights are blinking.

Result:





B -- CHECK BRAKE CONTROL SYSTEM (TS TERMINAL CIRCUIT)
A -- Continue to next step.

7. CHECK CAN COMMUNICATION SYSTEM

(a) Check if the CAN communication system DTC is output Adaptive Variable Suspension System.

Result:





C -- REPAIR CIRCUIT INDICATED BY OUTPUT CODE

B -- PROCEED TO NEXT CIRCUIT INSPECTION SHOWN IN PROBLEM SYMPTOMS TABLE

A -- REPLACE ABSORBER CONTROL ECU
