3. Move probe along component approximately 25 to 50 mm (1 to
2 in)/sec.
CHECKING PROCEDURE
To prevent inaccurate or false readings, make sure there is no refrigerant vapor, shop chemicals, or cigarette
smoke in the vicinity of the vehicle. Perform the leak test in calm area (low air/wind movement) so that the
leaking refrigerant is not dispersed.
1. Turn engine OFF.
2. Connect a suitable A/C manifold gauge set to the A/C service ports.
3. Check if the A/C refrigerant pressure is at least 345 kPa (3.45 bar, 3.52 kg/cm
2 , 50 psi) above 16°C
(61°F). If less than specification, recover/evacuate and recharge the system with the specified amount of
refrigerant.
NOTE:
At temperatures below 16°C (61°F), leaks may not be detected since the system may not reach 345 kPa (3.54
kg/cm
2 , 50 psi).
4. Conduct the leak test from the high side (compressor discharge a to evaporator inlet f) to the low side
(evaporator drain hose g to shaft seal i). Refer to AT C - 1 3 4 , "
Components" . Perform a leak check for the
following areas carefully. Clean the component to be checked and move the leak detected probe com-
pletely around the connection/component. ATC-134, "
Components" .
Compressor
Check the fitting of high and low pressure hoses, relief valve and shaft seal.
Liquid tank
Check the refrigerant pressure sensor.
Service valves
Check all around the service valves. Ensure service valve caps are secured on the service valves (to pre-
vent leaks).
NOTE:
After removing A/C manifold gauge set from service valves, wipe any residue from valves to prevent any
false readings by leak detector.
Cooling unit (Evaporator)
With engine OFF, turn blower fan on “High” for at least 15 seconds to dissipate any refrigerant trace in the
cooling unit. Wait a minimum of 10 minutes accumulation time (refer to the manufacturer′s recommended
procedure for actual wait time) before inserting the leak detector probe into the drain hose.
Keep the probe inserted for at least 10 seconds. Use caution not to contaminate the probe tip with water
or dirt that may be in the drain hose.
5. If a leak detector detects a leak, verify at least once by blowing compressed air into area of suspected
leak, then repeat check as outlined above.
6. Do not stop when one leak is found. Continue to check for additional leaks at all system components.
If no leaks are found, perform steps 7 - 10.
7. Start engine.
8. Set the heater A/C control as follows;
a. A/C switch: ON
b. Face mode
c. Intake position: Recirculation
d. Max cold temperature
e. Fan speed: High

On-vehicle ServiceNJBR0023OPERATING CHECKNJBR0023S011. Stop engine and depress brake pedal several times. Check
that pedal stroke does not change.
2. Depress brake pedal, then start engine. If pedal goes down
slightly, operation is normal.
AIRTIGHT CHECKNJBR0023S021. Start engine, and stop it after one or two minutes. Depress
brake pedal several times slowly. The pedal should go further
down the first time, and then it should gradually rise thereaf-
ter.
2. Depress brake pedal while engine is running, and stop engine
with pedal depressed. The pedal stroke should not change
after holding pedal down for30 seconds.
SBR232CB
RemovalNJBR0024CAUTION:
Be careful not to splash brake fluid on painted areas; it
may cause paint damage. If brake fluid is splashed on
painted areas, wash it away with water immediately.
Be careful not to deform or bend brake pipes, during
removal of booster.

InspectionNJBR0025OUTPUT ROD LENGTH CHECKNJBR0025S011. Apply vacuum of −66.7 kPa (−667 mbar, −500 mmHg, −19.69
inHg) to brake booster with a handy vacuum pump.
2. Add preload of 19.6 N (2 kg, 4.4 lb) to output rod.
3. Check output rod length.
Specified length:
10.275 - 10.525 mm (0.4045 - 0.4144 in)
