INSPECTION PROCEDURE

NOTICE:
Inspect the fuses for circuits related to this system before performing the following inspection procedure.

PROCEDURE

1. READ VALUE USING TECHSTREAM (IG POWER SOURCE VOLTAGE)

(a) Turn the engine switch off.

(b) Connect the Techstream to the DLC3.

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

(d) Turn the Techstream on.

(e) Enter the following menus: Chassis / KDSS / Data List.

(f) Select the item below in the Data List, and read the value displayed on the Techstream.

KDSS





Standard voltage:

11 to 14 V

NG -- CHECK HARNESS AND CONNECTOR (IG TERMINAL)
OK -- Continue to next step.

2. RECONFIRM DTC

(a) Clear the DTCs Kinetic Dynamic Suspension System.

(b) Check for DTCs Kinetic Dynamic Suspension System.

Result





B -- USE SIMULATION METHOD TO CHECK How To Proceed With Troubleshooting

A -- REPLACE STABILIZER CONTROL ECU

3. CHECK HARNESS AND CONNECTOR (IG TERMINAL)

(a) Disconnect the stabilizer control ECU connector.

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





Standard Voltage:





Text in Illustration





NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.

4. CHECK HARNESS AND CONNECTOR (GND TERMINAL)

(a) Disconnect the stabilizer control ECU 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 STABILIZER CONTROL ECU
