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) Check the DTC.





(1) Using SST, connect terminals between Tc and E1 of DLC1 or DLC2. SST 09843-18020
(2) Turn ignition switch ON.





(3) Read the DTC output by height control indicator light inside the meter.

HINT:
- When the engine is not starting, DTC "73" is output. This is not abnormal.
- When a DTC is not output, check the Tc terminal circuit.





As an example, the blinking patterns for normal code, 11 and 31 are as shown on the illustration.

(4) Refer to Trouble Code Descriptions for explanations of codes.
(5) After completing the check, disconnect terminals Tc and E1, and turn off the display.

HINT: In the event of 2 or more malfunction codes, indication will begin from the smaller numbered code and continue in order to the larger.
