Remove the YEL/RED wire from the engine oil pres-
sure swrtcn.
Check for continuity between the positive terminal
and the engine {ground). There should be continuity
with the engine stopped. There should be no conti-
nuity with the engine running.

Start the engine. Shut it off immedjately if the gauge
registers no oil pressure. Repair the problem before
continuing.
Allow the engine to reach operating temperature (fan
comes on at least twice). The pressure should be:
Engino Oil Temperature: 176'F (80'C)
Engine Oil Pressure:
At ldle:70 kPa (0.7 kgt/cm', 10 psil
minimum
Ai 3,000 rpm: 3/r0 kPa {3.5 kgt/cm', 50 psi)
minimum
lf oil pressure in not within specifications, inspect the
oil pump (see page 8-9).

ABS 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 has three modes: pressure reducing, pressure retaining, and pressure intensi{ying modes.
Self-diagnosis Function
The ABS control unit is equipped with a main cPU and a sub cPU, that check each other for problems.
The CPUs check the circuit of the system.
When the CPUS detect failure, they shift to the "system down mode" or the "control inhibition mode".
The self-diagnosis can be classitied into these four categories:
O: Initial diagnosis
O: Except ABS control
O; During ABS control
@: During warning
On-board Diagnosis Function
The ABS system can be diagnosed with the Honda PGM Tester.
The ALB Checker cannot be used with this system. For air bleeding. and checking wheel sensor signals, use the Honda
PGIM Tester. See the Honda PGM Tester user's manuals for specific operating instructions.

Turn SignallHazard Flasher System
Turn Signal/Hazard Relay Input Test
SRS components are located in this area. Review theSRS component /ocations, precautions, ano proceoures
in the SRS section (24) before performing repairs or ser-vice.
1.Remove the turn signal/hazard relay from the under-dash fuse/relay box.
Inspect the relay and luselrelay box socket terminals
to be sure they are all making good contact.
lf the terminals are bent, loose or corroded,reparr them as necessary, and recheck the system.lf the terminals look OK, make the following
input tests at the fuse/relay box socket.- lf any test indicates a problem, find and cor-
rect the cause, then recheck the system.- lf all the input tests prove OK, the turn signal/
hazard relay must be faulty; replace it.
