A/C Switch InspectionS7RS0B7216014
• Check that there is continuity between terminal (1) and terminal (2) when A/C s witch is at ON position.
• Check that there is no continuity between terminal (1) and terminal (2) when A/C s witch is at OFF position.
If check result does not meet the above conditions,
replace HVAC control unit.
Compressor Relay InspectionS7RS0B7216015
1) Disconnect negative (–) cable from battery.
2) Remove compressor relay (1) from main fuse box.
3) Check that there is no continuity between terminal “c” and “d”. If there is continuity, replace relay.
4) Connect battery positive (+ ) terminal to terminal “b”
of relay and battery negative (–) terminal to terminal
“a” of relay, and then check continuity between
terminal “c” and “d”. If there is no continuity, replace
relay.
Compressor Drive Belt Inspection and
Adjustment
S7RS0B7216016
Inspection
• Check compressor drive belt (1) for wear, crack, deformation and cleanliness. If any defect is found,
replace the belt with new one referring to
“Compressor Drive Belt Re moval and Installation”.
• Check compressor drive belt tension by measuring how much it deflects when pushed intermediate point
between magnet clutch pulley (6) and crankshaft
pulley (3) with about 100 N (10 kg) force after rotating
crankshaft pulley 360 °. If belt tension is out of
specification, adjust belt tension referring to
“Adjustment”.
Compressor drive belt tension
“a”
: 7 – 8mm (0.28 – 0.31 in.)
NOTE
When replacing drive belt, adjust drive belt
tension to the following specification.

New compressor dr ive belt tension “a”
: 6 – 7mm (0.24 – 0.28 in.)
Adjustment 1) Loosen tension pulley nut (4).
2) Adjust belt tension by ti ghten or loosen tension
pulley adjusting bolt (5).
3) Tighten tension pulley nut.
4) Rotate the crankshaft pulley 360 °, and then recheck
belt tension.
