INSPECTION PROCEDURE 5
No initial combustion (starting impossible)
In cases such as the above, the cause is probably that a spark plug is defective,
or that the supply of fuel to the combustion chamber is defective.
In addition, foreign materials (water, kerosene, etc.) may be mixed with the fuel.
Check battery voltage when cranking.
OK: 8 V or higher
Is immobilizer-ECU diagnosis code displayed?
MUT-II Data list
16 Power supply voltage (Refer to P.13A-176.)
Does the camshaft rotate at the engine cranking?
(When oil filler cap is removed.)
MUT-II Self-Diag code
Are diagnosis codes displayed?
MUT-II Data list
22 Crank angle sensor
OK: Cranking speed is displayed
MUT-II Actuator test
07 Fuel pump (Refer to P.13A-183.)
MUT-II Data list
21 Engine coolant temperature sensor (Refer to P.13A-176.)
Can any sound be heard from the injectors when cranking?
Measure at the ignition coil connector B-09
D Connect an engine tachometer, which detects primary
voltage, to terminal 3 while the engine is cranking.
OK: The engine tachometer indicates cranking speed.
Check the following items.
D Check the ignition coil, spark plugs, spark plug cables.
D Check if the injectors are clogged.
D Check if foreign materials (water, alcohol, etc.) got into fuel.
D Check the compression pressure.
D Check the immobilizer system.
