TC and CG Terminal Circuit

SUSPENSION CONTROL: ADAPTIVE VARIABLE SUSPENSION SYSTEM: TC and CG Terminal Circuit

TC and CG Terminal Circuit

DESCRIPTION

The DTC output mode is set by connecting terminals TC and CG of DLC3.
The DTCs are displayed by a blinking of the absorber control indicator light.

INSPECTION PROCEDURE
NOTE:
When replacing the absorber control ECU, check the acceleration sensor assembly signal after replacement Test Mode Procedure.
HINT: Check the condition of each related circuit connector before troubleshooting Electronic Circuit Inspection Procedure.

PROCEDURE

1. INSPECT TERMINAL VOLTAGE (DLC3 TC TERMINAL VOLTAGE)

(a) Turn the engine switch on (IG).
(b) Measure the voltage according to the value(s) in the table below.
Voltage:

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.
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 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 (ECM TO DLC3)
(a) Disconnect the ECM connector.

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

NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR (TC 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 TC TERMINAL INPUT)

(a) Using the SST, connect the terminals TC and CG of the DCL3.
SST: 09843-18040
(b) Check that the engine, ABS, and VSC warning lights are 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 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
