Oil Pressure
Use this procedure to tighten the filter if eight num-
bers (1 to 8) are printed on the surface of the filter.
1) Make a mark on the oil filter base under the num-
ber that shows at the bottom of the filter when
the rubber seal is seated.
2l Tighten the filter by turning it clockwise seven
numbers from the marked point. For example, if a
mark is made under the number 2 when the rub
ber seal is seated, the filter should be tightened
until the number 1 comes up to the marked point'
7/8 turn
Number when rubDer
seal is seated
Number after tightening.
CAUTION: Using any procedure other than those
shown could rosult in serious engins damage due
to oil leakage
5. After installation. fill the engine with oil up to the spec-
ified level, run the engine for more than three minutes,
then check for oil leakage

Testing
lf the oil pressure warning Iight stays on with the engine
running, check the engine oil level. It the oil level is cor-
rect:
1. Connect a tachometer'
2. Remove the engine oil pressure switch, and install an
oal pressure gauge.

ADAPTER(1/8\28. BSPTI
{CommerciallY availablei
Start the engine. Shut it off immediately if the gauge
registers no oil pr€ssure. Repair the problem before
continuing.
Allow the engine to reach operating temperature (tan
comes on at least tlivice). The pressure should be;
Engine Oil Temperature: 176"F (80"C1
Engine Oil Pressulo:
At ldle: 69 kPa (0.7 kgf/Gm'. 10 Psi)
minimum
At 3.000 rpm: 3/Ut kPa (3.5 kgt/cm', 50 psi)
minimum
. lf the oil Dressure is within specifications, replace
the oil pressure switch and recheck.
. lf the oil pressure is NOT within specifications,
inspect the oil pump (see page 8-10).

t-Operation
t
ABS Control Unit
Main Control
The ABS control unit detects the wheel speed based on the wheel sensor signal it received, then it calculates the vehicle
speed based on the detected wheel speed. The control unit detects the vehicle speed during deceleration based on the
rate of deceleration.
The ABS control unit calculates the slip rate of each wheel. and it transmits the control signal to the modulator unit
solenoid valve when the slip rate is high.
The pressure reduction control is a three-mode system, that is pressure reduction, pressure retaining and pressure intensi-
fying modes.
Self -diagnosis Funqtion
The ABS control unit is equipped with a main CPU and a sub CPU, and the CPUS check each other'
The CPUs check the circuit of the svstem.
When the CPUS detect failure, they shift to the "system down mode" or the "control inhibition mode"
The self-diagnosis can be classifield into these four categories:
O: Initial diagnosis
@: Except ABS control
@: During ABS control
@: During warning
On-board Diagnosis Funstion
The ABS control unit is connected to the data link connector {16P).
The ABS system can be diagnosed with the Honda PGM Tester.

Troubleshooting Precautions
ABS Indicator Light
I The ABS indicator light comes on when the ABS control unit detects a problem in the system. However, even thoughthe system is normal, the ABs indicator light can come on, too, under the following conditions. To determine theactual cause of the problem, question the customer about the problem, taking the following conditions into consider-ation.
. Signal disturbance
. Wheel soin
. Only drive wheels rotate. Battery voltage fluctuates
2. When a problem is detected and the ABS indicator light comes on, the indicator light can stay on untat the ignitionswitch is turned off, or it can automatically go off, depending on the mode.. Lightstayson until the ignition switch isturned off;When the system is inthesvstem down mode.o Light automatically goes off:When the system is in the control inhibition mode.(refer to symptom-to-system chart)3 The ABS indicator light stays on when the system is reactivated without erasing the DTC, but it goes off after startingthe car.
when the wheel sensor system is faulty and the ABS indicator light comes on, the algorithm of the system automaticallyturns off the ABS indicator light after the wheel speed signal returns to the normal speed. while, when the DTC is erased,the CPU is reset and the ABS indicator light goes off when the system check€d out normal by the initial diagnosis.Therefore, test-drive the car after servicing the wheel sensor system, and be sure that the ABS indicator light does notcome on.
4. When the ABS control unit outputs battery voltage to the gauge assembty, the ABS indicator light goes off.
Diagnostic Trouble Code (DTC)
1. The diagnostic trouble code (DTC) is memorized when a problem is detected and the ABS indicator light does not gooff, or when the ABS indicator light comes on.The DTC is not memorized when the ABs indicator right comes on unress the cpU is activated.2. The memory can hold any number of DTCs. However, when the same DTc is detected twice or more, the later one iswritten over the old one.
Therefore. when the same problem is detected repeatedly, it is recorded as one DTC.3. The DTCS are indicated in the order of ascending number, not in the order thev occur.4. The DTCS are memorized in the EEpROM {non-volatile memorv}.Therefore, the memorized DTCS cannot be canceled by disconnecting the battery. perform the specified orocedures toerase.
Solf-diagnosis
1. The self-diagnosis can be classifield into these four categories:' Initial diagnosis; Performed right after the engine sta rts and untiltheABs indicator light goes off.o Except ABS control: Performed when the ABS is not functioning,. During ABS control: Performed when the ABS is functioning.. During warning: Performed when the ABS indicator light is ON.2 The system performs the following controls when a problem is detected by the self-diagnosis:. ABS indicator light ON. Memory of DTC
. Mode change to the "system down mode,, or the "control inhibition mode,,.
