check engine NISSAN PRIMERA 1999 Electronic Workshop Manual

1. Loosen lock nut and adjust pedal free height by turning brake
booster input rod. Then tighten lock nut.
2. Check pedal free play.
Make sure that brake lamps go off when pedal is released.
3. Check brake pedal's depressed height while engine is run-
ning.
If depressed height is below specified value, check brake
system for leaks, accumulation of air or any damage to com-
ponents (master cylinder, wheel cylinder, etc.); then make
necessary repairs.

OPERATING CHECK
1. Depress brake pedal several times with engine off. After
exhausting vacuum, make sure there is no change in pedal
stroke.
2. Depress brake pedal, then start engine. If pedal goes down
slightly, operation is normal.
AIRTIGHT CHECK
1. Start engine, and stop it after one or two minutes. Depress
brake pedal several times slowly. Booster is airtight if pedal
stroke is less each time.
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.
Removal
CAUTION:
lBe 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.
lBe careful not to deform or bend brake pipes, during
removal of booster.

Inspection
1. Check control lever for wear or other damage. Replace if
necessary.
2. Check wires for discontinuity or deterioration. Replace if nec-
essary.
3. Check warning lamp and switch. Replace if necessary.
4. Check parts at each connecting portion and, if found
deformed or damaged, replace the parts.
Adjustment
Before or after adjustment, pay attention to the following points.
lMake sure the toggle lever of the rear disc brakes returns to
stopper, when the parking lever is released.
lThere is no drag when parking brake lever is released.
lVehicle is unladen.
1. Adjust clearance between shoe and drum or pad and rotor
as follows:
a. Release parking brake lever and loosen adjusting nut.
b. Depress brake pedal fully at least 10 times with engine run-
ning.
2. Pull control lever 10 times or more to make a lever stroke of
203.5 mm (8.01 in). At6-8notches, adjust the parking brake
cable by turning the adjusting nut.
3. Pull control lever with the specified amount of force. Check
lever stroke and ensure smooth operation.

CONSULT-II Inspection Procedure
SELF-DIAGNOSIS PROCEDURE
1) Turn ignition switch to the ªLOCKº
position.
2) Connect CONSULT-II to Data Link
Connector.
1) Start engine.
2) Drive vehicle over 30 km/h (19 mph)
for at least one minute.
1) Stop vehicle with engine run-
ning and touch ªSTARTº on
CONSULT-II screen.
2) Touch ªABSº.
3) Touch ªSELF-DIAG RESULTSº.
lThe screen shows the detected
malfunction and how many times
the ignition switch has been
turned since the malfunction.
MALFUNCTION REPAIR
----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Make the necessary repairs following
the diagnostic procedures.
After repairing the malfunctions, erase
the self-diagnostic results stored in the
control unit by touching ªERASEº.
Check warning lamp for deactivation
after driving vehicle over 30 km/h (19
mph) for at least one minute.
End
Note: ªSELF-DIAG RESULTSº screen shows the detected malfunction
and the times of ignition switch on and off after it occurred.
