DTC CONFIRMATION PROCEDURE
1.INSPECTION START
Do you have CONSULT?
Do you have CONSULT?
YES >> GO TO 2.
NO >> GO TO 5.
2.PRECONDITIONING
If DTC Confirmation Procedure has been previously conducted, always perform the following procedure
before conducting the next test.
1. Turn ignition switch OFF and wait at least 10 seconds.
2. Turn ignition switch ON.
3. Turn ignition switch OFF and wait at least 10 seconds.
>> GO TO 3.
3.CHECK VEHICLE SPEED SENSOR FUNCTION
NOTE:
This procedure may be conducted with the drive wheels lifted in the shop or by driving the vehicle. If a
road test is expected to be easier, it is unnecessary to lift the vehicle.
With CONSULT
1. Start engine.
2. Read “VHCL SPEED SE” in “DATA MONITOR” m ode with CONSULT. The vehicle speed on CONSULT
should exceed 10 km/h (6 mph) when rotating wheels with suitable gear position.
Is the inspection result normal?
YES >> GO TO 4.
NO >> Go to EC-333, "
Diagnosis Procedure".
4.PERFORM DTC CONFIRMATION PROCEDURE
1. Select “DATA MONITOR” mode with CONSULT.
2. Warm engine up to normal operating temperature.
3. Maintain the following conditions for at least 60 consecutive seconds. CAUTION:
Always drive vehicle at a safe speed.
DTC No. Trouble diagnosis content DTC detecting condition Possible cause

P0506 ISC SYSTEM
P0506 ISC SYSTEM
DescriptionINFOID:0000000012431528
The ECM controls the engine idle speed to a specified leve
l through the fine adjustment of the air, which is let
into the intake manifold, by operating the electric thrott le control actuator. The operating of the throttle valve is
varied to allow for optimum control of the engine idli ng speed. The crankshaft position sensor (POS) detects
the actual engine speed and sends a signal to the ECM.
The ECM controls the electric throttle control actuator so that the engine speed coincides with the target value
memorized in the ECM. The target engine speed is the lowest speed at which the engine can operate steadily.
The optimum value stored in the ECM is determined by taking into consideration various engine conditions,
such as during warming up, deceleration, and engine l oad (air conditioner, power steering and cooling fan
operation, etc.).
