NOTE
If the engine warning lamp illuminates because of a malfunction of the engine-ECU, communication between
MUT-IIand the engine-ECU is impossible. In this case, the diagnosis code cannot be read.
METHOD OF READING AND ERASING DIAGNOSIS
CODES
Refer to GROUP 00 - How to Use Troubleshooting/Inspection
Service Points.
INSPECTION USING MUT-IIDATA LIST AND ACTUATOR
TESTING
1. Carry out inspection by means of the data list and the
actuator test function. If there is an abnormality, check
and repair the chassis harnesses and components.
2. After repairing, re-check using the MUT-IIand check that
the abnormal input and output have returned to normal
as a result of the repairs.
3. Erase the diagnosis code memory.
4. Remove the MUT-II, and then start the engine again and
carry out a road test to confirm that the problem has
disappeared.

CONFIRMING FREEZE FRAME DATA
When the engine-ECU detects a malfunction and stores a diagnosis code, it also stores a current status
of the engine. This function is called “Freeze frame” data. By analyzing this “Freeze frame” data with
MUT-II, an effective troubleshooting can be performed.
NOTE
If mulfunctions have been detected in multiple systems, engine-ECU stores one malfunction only, which
has been detected first.

FAIL-SAFE FUNCTION REFERENCE TABLE
When the main sensor malfunctions are detected by the diagnosis function, the vehicle is controlled
by means of the pre-set control logic to maintain safe conditions for driving.
Malfunctioning itemControl contents during malfunction
Air flow sensor1. Uses the throttle position sensor signal and engine speed signal (crank angle sensor
signal) to take reading of the basic injector drive time and basic ignition timing from
the pre-set mapping.
2. Fixes the idle speed control servo in the appointed position so idle control is not
performed.
Intake air temperature
sensorControls as if the intake air temperature is 25_C.
Throttle position
sensorNo increase in fuel injection amount during acceleration due to the throttle position sensor
signal.
Engine coolant
temperature sensor1. Controls as if the engine coolant temperature is 80_C.
(Even after sensor signal is correctly recovered, continues until the ignition switch
is set to the “LOCK” (OFF) position.)
2. Rotates radiator fan and condenser fan at high speed.
Camshaft position
sensor1. Inject all fuel cylinders simultaneously. (However, when the No.1 cylinder top dead
centre is not detected at all after the ignition switch is turned to “ON” position.)
2. Shuts off fuel supply after 4 seconds have passed since a failure was detected.
(However, when the No.1 cylinder top dead centre is not detected at all after the
ignition switch is turned to “ON” position.)
Barometric pressure
sensorControls as if the barometric pressure is 101 kPa.
Detonation sensorSwitches the ignition timing from ignition timing for super petrol to ignition timing for standard
petrol.
Alternator FR terminalDoes not control the output of the alternator according to an electrical load. (works as a
normal alternator)
