Initial Inspection and Diagnostic Overview

If any fault or trouble occurs, the air suspension indicator light ("Hi" mark) located above the height control switch blinks.

There are two types of diagnostic items. One type is checked immediately after the ignition switch is turned ON; the other type is checked at least 10 minutes after the switch has been turned ON.

When a problem is shown on the indicator, it can be determined by reading a trouble code (which is indicated in terms of the number of indicator light blinks) during SELF-DIAGNOSIS.

Problems which occurred in the past are stored in memory for ready reference. When the indicator light does not show a trouble code, the *select monitor (scan tool) is used to measure the characteristics of sensors, etc. to determine the item in problem.
*: Applicable cartridge of select monitor is type "H" (No.498348800).
