1. RUN ENGINE AT APPROX. 1,500 RPM 2. OPERATE AIR CONDITIONER AT MAXIMUM COOLING FOR A FEW MINUTES 3. CHECK AMOUNT OF REFRIGERANT Observe the sight glass on the receiver. Insufficient* (1) Check for gas leakage with gas leak Bubbles present in sight glass tester and repair if necessary (2) Add refrigerant until bubbles disappear Refer to items 3 and 4 No bubbles present in sight glass None, sufficient or too much Empty or nearly empty (1) Check for gas leakage with gas leak No temperature difference between tester and repair if necessary compressor inlet and outlet (2) Add refrigerant until bubbles disappear Refer to items 5 and 6 Proper or too much Temperature between compressor inlet and outlet is noticeably different (1) Recover refrigerant Immediately after air conditioner is turned Too much (2) Evacuate air and charge proper off, refrigerant in sight glass stays clear amount of purified refrigerant When air conditioner is turned off, Proper refrigerant foams and then stay clear

CHECK THAT PEDAL HEIGHT IS CORRECT Pedal height from floor panel: 42.8-152.8 mm (5.62-6.02 in.) If the pedal height is incorrect, adjust it. IF NECESSARY, ADJUST PEDAL HEIGHT (a) Remove the under cover. (b) Remove the lower pad and air duct. (c) Remove the power steering ECU and disconnect the connector from the stop light switch. (d) Loosen the stop light switch lock nut and remove the stop light switch. (e) Loosen the push rod lock nut. (f) Adjust the pedal height by turning the pedal push rod. (g) Tighten the push rod lock nut. Torque: 25 N?m (260 kgf?cm, 19 ft?lbf) (h) Install the stop light switch and turn it until it lightly contacts the pedal stopper. (i) Return the stop light switch one turn. (j) Check that the clearance (A) between stop light switch and pedal. Clearance: 1.5-2.6 mm (0.06-0.10 in.) (k) Tighten the stop light switch lock nut.

Temporary Driving Conditions: 1. The ABS indicator light comes on and the ABS con- trol unit memorizes the diagnostic trouble code (DTC) under certain conditions. NOTE: The DTCs are explained on page 19-56. • The tire(s) adhesion is lost due to excessive cor- nering speed. DTC: 5, 5-4, 5-8. • The vehicle loses traction when starting from a stuck condition on a muddy, snowy, or sandy road. DTC: 4-1, 4-2, 4-4, 4-8. • When the parking brake is applied for more than 30 seconds while the vehicle is being driven. DTC: 2-1. • The vehicle is driven on an extremely rough road. The ABS is OK, if the ABS indicator light goes off after the engine is restarted.

ON?VEHICLE INSPECTION 1. INSPECT INJECTOR OPERATION Check operation sound from each injector. (a) With the engine running or cranking, use a sound scope to check that there is normal operating noise in proportion to engine rpm. (b) If you have no sound scope, you can check the injector transmission operation with your finger. If no sound or unusual sound is heard, check the wiring connector, injector or injection signal from the ECU. 2. INSPECT INJECTOR RESISTANCE (a) Disconnect the injector connector. (b) Using an ohmmeter, measure the resistance between the terminals. Resistance: Approx. 13.8W If the resistance is not as specified, replace the injector. (c) Reconnect the injector connector.
