System is equipped with a cycling clutch system that uses an expansion valve in refrigerant line between condenser and evaporator, near condenser. System is engaged when A/C switch on control panel is pressed. See Fig. 1. Pressure switch on accumulator cycles compressor clutch on and off. Blower fan speed is controlled by sliding switch on lower left of A/C-heater control panel.

1. Take the kit out of the box and lay everything out. You can install either the ballasts or bulbs first but typically it is easier to install the bulbs first.
2. Remove the access cap from the rear of your headlight housing as shown.
3. Drill a hole in the center of the cap as shown. If you use a hole saw that will be all you need. If you use the small drill bit you will need to use your dremel to cut a 1″ hole. You may want to use some sand paper just to smooth the edges you have cut.

Vehicles are equipped with an integral housing steering rack that is sealed and must be replaced if defective.
FLUID LEVEL CHECK
Check fluid level when fluid is cold with engine off. To check and fill, remove fluid level gauge from reservoir and check fluid level. Fluid level should be between MIN and MAX marks on gauge dipstick. Add fluid through dipstick opening as needed, and recheck fluid level. DO NOT overfill.

The condition of camshaft drive belts should always be checked on vehicles which have more than 50,000 miles. Although some manufacturers do not recommend belt replacement at a specified mileage, others require it at 60,000-100,000 miles. A camshaft drive belt failure may cause extensive damage to internal engine components on most engines, although some designs do not allow piston-to-valve contact. These designs are often called “Free Wheeling”.

Before testing separate components or systems, perform procedures in the F - BASIC TESTING - TURBO article. Since many computer-controlled and monitored components set a trouble code if they malfunction, also see the G - TESTS W/CODES - TURBO article.
NOTE: Testing individual components does not isolate shorts or opens. Unless stated otherwise in test procedure, perform all voltage tests using a Digital Volt-Ohmmeter (DVOM) with a minimum 10-megohm input impedance. Use ohmmeter to isolate wiring harness shorts or opens.

850 turbo uses a Motronic 4.3 control system, which has a single Electronic Control Module (ECM) to control fuel injection and ignition systems. In addition, Motronic 4.3 control system incorporates an on-board diagnostic function. Signals from various sensors are monitored continuously. If certain signals are lost or become faulty, ECM will adopt fixed substitute values (limp-home mode) to enable vehicle to be driven for certain failures. Substitute values can be adopted for Engine Coolant Temperature (ECT) sensor signal, Throttle Position (TP) sensor signal, Mass Airflow (MAF) sensor signal, and oxygen sensor (HO2S) signal. See Fig. 1.

The Electronic Climate Control (ECC) module (A/C-heater control panel) contains a function selector dial, driver’s and passenger’s temperature dials, a REC (recirculated air) switch, A/C OFF switch, and a fan speed (blower motor) control lever. See Fig. 1. The heater (blower motor) fan is controlled by ECC output (power) stage. Air conditioning system will only operate above 32 £ F (0 £ C). Blower switch must not be in zero position to allow compressor to engage.

If no faults were found while performing procedures in the F - BASIC TESTING article, proceed with self-diagnostics. If no fault codes are present, proceed to the H - TESTS W/O CODES article for diagnosis by symptom (i.e., ROUGH IDLE, NO START, etc.). NOTE: All voltage tests should be performed using a Digital Volt-Ohmmeter (DVOM) with a minimum 10-megohm input impedance, unless stated otherwise in testing procedures.

All 850 models are equipped with an analog gauge instrument cluster. Speedometer is centrally located with tachometer on right and coolant temperature/fuel gauges on left. Warning/telltale lights arelocated at bottom left and right sides of instrument cluster. Digital clock and ambient temperature display are located under odometer. This section of instrument cluster may contain an optional trip computer that provides information on average fuel consumption, current fuel consumption, average speed, trip meter, ambient temperature and range of fuel in tank. Instrument cluster is equipped with self-diagnostic capabilities.

When ignition is turned on, control module activates warning indicators on instrument panel and performs an initial diagnostic test which ensures there are no internal faults in control module. At same time, main relay portion of combination relay is activated so hydraulic modulator valves are supplied with power. See Fig. 1. Control module then checks operation of valves by activating them in sequence.
