With Manufacturer's Scan Tool

DIAGNOSIS SYSTEM





(a) Check the indicator light.
(1) Turn ignition switch ON.
(2) Check that height control indicator lights come on immediately.

HINT:
- When the height control switch is pressed to the "HIGH" side, the height control indicator light continues to light up
- When the height control indicator light flashes at 1 second intervals, it indicates that the ECU stores the malfunction codes in memory.





If trouble occurs, shown in the above table, in the indicator light check, proceed to check the corresponding circuit and carry out troubleshooting.





(b) Using LEXUS hand-held tester, check the DTC.
(1) Hook up the LEXUS hand-held tester to the DLC2.
(2) Read the DTCs by following the prompts on the tester screen.
Please refer to the LEXUS hand-held tester operators manual.
