3. Check A.T.C. system for function by proceed-ing as follows:

Confirm that engine is cold before starting test. With engine turned off, check position of air contro! valve by hand or mirror.

5. Install new spark plugs. Reconnect high tension cables according to Nos. indicated on them.

CHECKING IGNITION WIRES (HIGH-TENSION CABLES)

1. Check the high-tension cables for cracks, dam-age, burned terminals and proper fit.

Air control valve is in correct position if its cold air inlet is open and hot air inlet is closed.

4.    Start engine and keep idling.

Immediately after starting engine, air control valve is in correct position if its cold air inlet is closed and hot air inlet is open.

5.    Check that air control valve gradually opens to cold air inlet side as engine warms up. When environmental temperaturę around temperaturę sensor is Iow, allow morę time for engine warming up to facilitate smooth operation of air control valve.

If the above test reveals any problem in the operation of air control valve, carry out the further inspection described in Section EF.

2. Shake the high-tension cable while measuring resistance to check for intermittent breakes.

CHECKING AUTOMATIC TEMPERATURĘ

CONTROL (A.T.C.) AIR CLEANER

1.    Check that vacuum hoses (Intake manifold to temperaturę sensor, idle compensator and vacuum motor) are securely connected in correct position.

2.    Check each hose for cracks or distortion.
