FUEL WARNING LAMP (See P.B-156.)
OIL PRESSURE WARNING LAMP (See P.B-157.)
BRAKE WARNING LAMP (See P.B-157.)
OPERATION

DWhen the ignition switch is at the “ON” position,
the fuel gauge unit resistance is small when
the fuel level is high, and the fuel gauge unit
resistance is large when the fuel level is low.
When this resistance rises above a specified
value, the fuel warning lamp illuminates to notify
the driver that the fuel level is low.

DWhen the lubrication system fails after engine
starting, resulting in the oil pressure failing to
build up, the oil pressure switch turns on
causing the oil pressure warning lamp to
illuminate.

DWhen the brake fluid level goes down below
a predetermined level with the ignition switch
in the “ON” position, the brake fluid level switch
is activated or the parking brake switch is turned
on, causing the brake warning lamp to
illuminate.TROUBLESHOOTING HINTS
1. No warning lamps illuminate.
DCheck multi-purpose fuse No.(2).
2. Some warning lamps do not illuminate.
DCheck lamp valve.
DCheck the switches and the gauge unit.

ENGINE -On-vehicle ServiceENGINE -On-vehicle Service11A-10
Standard value: 5_BTDC±3_
5. Run the engine at idle for 2 minutes.
6. Check the idle speed. Select item No. 22 and take a
reading of the idle speed.
Curb idle speed: 850±100 r/min
NOTE
The idle speed is controlled automatically by the idle speed
control (ISC) system.
7. If the idle speed is outside the standard value, check
the MPI components by referring to GROUP 13A -
Troubleshooting.
8. Remove the timing light.
9. Turn the ignition switch to the “LOCK” (OFF) position
and then remove the MUT-II.
IDLE MIXTURE CHECK
1. Before inspection, set the vehicle to the pre-inspection
condition.
2. Turn the ignition switch to the “LOCK” (OFF) position,
and then connect the MUT-IIto the diagnosis connector.
3. Set the timing light.
4. Check that the basic ignition timing is within the standard
value.
Standard value: 5_BTDC±3_
5. Run the engine at 2,500 r/min for 2 minutes.
6. Set the CO, HC tester.
7. Check the CO contents and the HC contents at idle.
Standard value
CO contents: 0.1% or less
HC contents: 100 ppm or less
8. If there is a deviation from the standard value, check the
following items:
DDiagnosis output
DClosed-loop control (When the closed-loop control
is normal, the output signal of the oxygen sensor
changes between 0 - 400 mV and 600 - 1,000 mV
at idle.)
DFuel pressure
DInjector
DIgnition coil, spark plug cable, spark plug
DEvaporative emission control system
DCompression pressure
NOTE
Replace the three way catalyst when the CO and HC
contents are not within the standard value, even though
the result of the inspection is normal on all items.
9. Remove the timing light.
MUT-II
