Idle HONDA CIVIC 2000 6.G Workshop Manual

Brake Booster InsPection
FunctionalTest
1. With the engine stopped, depress the brake pedal
several times to deplete the vacuum reservoir, then
depress the pedal hard and hold it for 15 seconds lf
the pedal sinks' either the master cYlinder is
bypassing internally, or the brake system (master
cylinder. lines. modulator, proportioning control
valve, or caliPer) is ieaking.
2. Start the engine with the pedal depressed lf the
pedal sinks slightly, the vacuum booster is operating
normally. lf the pedal height does not vary, the
booster or check valve is faultY.
3. With the engine running. depress the brake pedal
lightly. Apply just enough pressure to hold back
automatic transmission creep. lf the brake pedal
sinks more than 25 mm (1.0 in.) in three minutes,
the master cvlinder is faulty. A slight change in
pedal height when the A'lC compressor cycles on
and off if normal. (The A/C compressor load
changes the vacuum available to the booster')
Leak Test
1. Depress the brake pedal with the engine running.
then stop the engine. lf the pedal height does not
vary while depressed for 30 seconds, the vacuum
booster is OK. lf the pedal rises. the booster is
faulty.
2, With the engine stopped, depress the brake pedal
several times using normal pressure When the
Dedal is first depressed, it should be low On con-
secutive applications, the pedal height should grad-
uallv rise. lf the pedal position does not vary, checK
the booster check valve.

Booster Check Valve Test
1. Disconnect the brake booster vacuum hose at the
booster.
2. Stan the engine and let it idle. There should be vac-
uum. lf no vacuum is available, the check valve is
not working properly. Replace the brake booster
vacuum hose and check valve, and retest.

-lgnition Timing Inspection and Setting
1.Check the idle speed, and adjust it it necessary (see
section 'l '1 ).
Pull out the service check connector 2P (BRN and BLK
wires) from the connector holder located under the
dash on the front passenger side, then connect the
SCS service connector (T/N 07PAZ - 0010'100) to it.
Start the engine. Hold the engine at 3.000 rpm with
no load {A,/T in E or E. M/T in neutral) until the
radiator fan comes on, then let it idle.
Connect the timing light to the No. 1 ignition wire,
then point the light toward the pointer on the timing
belt cover.
Check the ignition timing in no load conditions:
headlights. blower fan, rear window defogger, and
air conditioner are not operating.

Actuator Cable Adjustment
Check that the actuator cable operates smoothlywith no binding or sticking.
Stan the engine. Hold the engine at 3,000 rpm withno load (Afl'in N or E, M/T in neutral) untit theradiator fan comes on, then let it idle.
Measure the amount of movement of the actuato.rod until the cable pulls on the accelerator lever(engine speed starts to increase). Free Dlay shouldbe 11 t 1.0 mm (0.43 I 0.04 in).
LOCKNUT FREE PLAY: 11 1 1.0 mm
{o.i|:l r 0.oit in}
lf free play is not within specs, loosen the locknut,
and turn the adjusting nut as required.
NOTE: lf necessary. check the throttle cable freeplay (see section 11). then recheck the actuator rodfree play.
Retighten the locknut, and recheck the free play.

)Erasing the DTC Memory
To erase the DTC(s) from the SRS unit, use a Honda
PGM Tester (see the Honda PGM Tester SRS vehicle
System Supplement) or the following procedure
1. Make sure the ignition switch is OFF
2. Connect the SCS service connector to the MES con-
nector (2P). Do not use a jumper wlre.

Turn the ignition switch ON (ll).
The SRS indicator light comes on for about six sec-
onds and goes off. Remove the SCS service connec-
tor from the MES connector (2P) within four seconds
after the SRS indicator light went off.
The SRS indicator light comes on again. Reconnect
the SCS service connector to the lvlES connector
(2P) within the four seconds after the SRS indicator
light comes on.
The SRS indicator light goes off. Remove the SCS
service connector from the MES connector (2P)
within four seconds.
The SRS indicator light indicates that the memory is
erased by blinking two times.
Turn the ignition switch OFF, and wait for ten sec-
onos.

Troubleshooting Intermittent
Failures
lf there was a malfunction, but it doesn't recur, it will be
stored in the memory as an intermittent failure, and the
SRS indicator light comes on.
Afte. checking the DTC, troubleshoot as lollows:
1. Read rhe DTC {see "Reading the DTC"}.
Erase the DTC memory (see "Erasing the DTC
Memory").
With the shifi lever in neutral, turn the ignition switch
ON (ll), and lei the engine idle.
The SRS indicator light comes on for about six sec-
onds and goes off.

Shake the wire harness and the connector, take a test
drive (quick acceleration, quick braking, cornering),
and turn the steering wheel fully left and right, and
hold it there for five lo ten seconds to find the cause
of the intermittent failure.
lf the problem recurs, the SRS indicator light will
stay on.
