Inspection Procedure 2
ID code cannot be registered using the MUT-II.
Probable cause
The cause is probably that there is no ID code registered in the immobilizer-ECU,
or there is a malfunction of the immobilizer-ECU.
Malfunction of the transponder

Malfunction of the ignition key ring antenna

Malfunction of harness or connector

Malfunction of the immobilizer-ECU
No ignition key can be registered.NOReplace the ignition key that cannot be
registered.Re-register the ID code.
(Refer to P.54-21.)
YES
Is a diagnosis code output?NOTo INSPECTION CHART FOR DIAG-
NOSIS CODE (Refer to P.54-13.)
YES
Check the immobilizer-ECU power
source and earth circuit. (Refer to
INSPECTION PROCEDURE 4.)OKCheck trouble symptoms.NGReplace the immobilizer-ECU.
Inspection Procedure 3
Engine does not start (cranking but no initial combustion).
Probable cause
If the fuel injectors are not operating, there might be a problem with the MPI system
in addition to a malfunction of the immobilizer system.
It is normal for this to occur if an attempt is made to start the engine using a key
that has not been properly registered.

FUEL GAUGE SIMPLE CHECK
Remove the fuel gauge unit connector.
Use the special tool to connect a test
lamp (12 V – 3.4 W) to the harness
connector. (Refer to Fig.1)
When the ignition switch is turned to
ON, the test lamp illuminates.OKThe needle of the fuel gauge moves.OKReplace the fuel gauge unit.
NG
Replace the fuel gauge.NG
Repair the harness.
FUEL GAUGE UNIT CHECK
Remove the fuel gauge unit from the fuel tank.
FUEL GAUGE UNIT RESISTANCE
1. Check that resistance value between the fuel gauge unit
terminal and earth terminal is at standard value when
fuel gauge unit float is at point F and point E.
Standard value:
Float positionMainSub
Point F1.8 ±1.2 Ω1.2 ±0.8 Ω
Point E65.2 ±4 Ω44.8 ±8 Ω
2. Check that resistance value changes smoothly when float
moves slowly between point F and point E.

IDLE-UP OPERATION CHECK
1. Before inspection and adjustment, set vehicle in the
pre-inspection condition:
2. Check whether or not the idle speed is the standard value.
Standard value: 700 ± 50 r/min
NOTE
There is no necessity to make an adjustment, because
the idle speed is automatically adjusted by the ISC system.
If, however, there occurs a deviation from the standard
value for some reason, check the fuel control system.
3. When the A/C is running after turning the A/C switch
to ON, check to be sure that the idle speed is at the
standard value.
