FUEL CUT RPM
FUEL CUT RPM INSPECTION
1. WARM UP ENGINE
Allow the engine to warm up to normal operating tempera-
ture.
2. CONNECT TACHOMETER TO ENGINE
Connect the tester probe of a tachometer to terminal IG of
the DLC1.
NOTICE:
wNever allow the tachometer terminal to touch ground as
it could result in damage to the igniter and/or ignition
coil.
wAs some tachometers are not compatible with this igni-
tion system, we recommend that you confirm the compat-
ibility of your unit before use.
3. INSPECT FUEL CUTOFF OPERATION
(a) Increase the engine speed to at least 3,000 rpm.
(b) Check for injector operating noise.
(c) Check that when the throttle lever is released, injector
operation noise stops momentarily and then resumes.
HINT: Measure with the A/C OFF.
Fuel return speed:
1,400 rpm
(Vehicle speed less than 25 km/h (16mph), with
brake OFF)

4. CHECK FOR FOAMING OR EMULSIFICATION
If there is foaming or emulsification, bleed power steering
system.
(See page SR±9)
5. CHECK FLUID LEVEL RISE
(a) With the engine idling, measure the fluid level in the reservoir.
(b) Stop the engine.
(c) Wait a few minutes and remeasure the fluid level in the
reservoir.
Fluid level rise mm (in.)
Maximum5(02) Maximum5 (0.2)
If a problem is found, bleed power steering system.
(See page SR±9)
6. CHECK FLUID LEVEL
POWER STEERING FLUID
REPLACEMENT
1. JACK UP FRONT OF VEHICLE AND SUPPORT IT WITH
STANDS
2. DRAIN FLUID
(a) Disconnect the return hose from the PS vane pump.
(b) Turn the steering wheel from lock to lock.
3. FILL OIL RESERVOIR
(a) Fill oil reservoir with fresh fluid.
Fluid:
ATF DEXRON[ II
(b) Start engine.
(c) After 1 or 2 seconds, fluid will begin to discharge from the
return hose.
(d) Stop the engine immediately.
NOTICE: Take care that some fluid remains in the oil res-
ervoir.
(e) Repeat steps (a), (b), (c) and (d) until there is no more air in
fluid.
(f) Connect the return hose.
