Quick Test
NOTE:
The QUICK TEST is a functional test of the IVSC system consisting of basic test steps and must be performed first. These steps must be carefully followed in sequence. Otherwise, mis-diagnosis or replacement of non-faulty components may result.
- Visually check for obvious faults and properly prepare vehicle for testing. Check all engine vacuum hoses for leaks or pinched hoses (servo-to-dump valve and servo-to-manifold vacuum). Check IVSC and EEC system wiring harness electrical connections for proper connections, loose or detached connectors, corrosion and proper routing of harness.
- Check EEC-IV ECA, IVSC sensors and actuators for physical damage. Perform all safety steps required to start and run vehicle tests. Apply emergency brake. Place shift lever in "PARK" or "NEUTRAL".
- Turn off all electrical loads and ensure doors are closed whenever readings are made. Verify engine coolant is at specified level. Start engine and idle until upper radiator hose is hot and pressurized, and throttle is off fast idle.
- Turn ignition key off. Service items as required, and proceed to equipment hookup. See Fig 2 .
