SUSPENSION CONTROL: AIR SUSPENSION SYSTEM: DATA LIST / ACTIVE TEST

DATA LIST / ACTIVE TEST

1. READ DATA LIST
HINT: Using the intelligent tester or Techstream to read the Data List allows the values or states of switches, sensors, actuators and other items to be read without removing any parts. This non-intrusive inspection can be very useful because intermittent conditions or signals may be discovered before parts or wiring is disturbed. Reading the Data List information early in troubleshooting is one way to save diagnostic time.
NOTE: In the table below, the values listed under "Normal Condition" are reference values. Do not depend solely on these reference values when deciding whether a part is faulty or not.

(a) Turn the power switch OFF.
(b) Connect the intelligent tester or Techstream to the DLC3.
(c) Turn the power switch ON (IG).
(d) Turn ON the tester.
(e) Enter the following menus:
(1) Intelligent tester - Select: DIAGNOSIS / OBD/MOBD / CHASSIS / AIR SUSPENSION / DATA LIST.
(2) Techstream - Select: Chassis / Air suspension / Data List.
(f) According to the display on tester, read the "DATA LIST".

2. PERFORM ACTIVE TEST
HINT: Using the intelligent tester or Techstream to perform Active Tests allows relays, VSVs, actuators and other items to be operated without removing any parts. This non-intrusive functional inspection can be very useful because intermittent operation may be discovered before parts or wiring is disturbed. Performing Active Tests early in troubleshooting is one way to save diagnostic time. Data List information can be displayed while performing Active Tests.

(a) Turn the power switch OFF.
(b) Connect the intelligent tester or Techstream to the DLC3.
(c) Turn the power switch ON (IG).
(d) Turn ON the tester.
(e) Enter the following menus:
(1) Intelligent tester - Select: DIAGNOSIS / OBD/MOBD / CHASSIS / AIR SUSPENSION / ACTIVE TEST.
(2) Techstream - Select: Chassis / Air suspension / Active Test.
(f) According to the display on tester, perform the "ACTIVE TEST".
