P0506 ISC SYSTEM
DescriptionINFOID:0000000009462306
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 t he 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.).

DTC CONFIRMATION PROCEDURE
1.PRECONDITIONING
TESTING CONDITION:
Before performing the following procedure, confi rm that battery voltage is 10 V or more at idle.
With CONSULT
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.
4. Turn ignition switch ON.
5. On the CONSULT screen, select âENGINEâ >> âDATA MONITORâ >> âCOOLAN TEMP/Sâ.
6. Check âCOOLAN TEMP/Sâ indication value.
With GST
Follow the procedure âWith CONSULTâ above.
Is the value of
âCOOLAN TEMP/Sââ5°C (23°F) and 45°C (11 3°F)?
YES >> GO TO 2.
NO-1 [if it is below â 5 °C (23 °F)]>>Warm up the engine until the value of âCOOLAN TEMP/Sâ indicates â5 °C
(23 °F) and 45 °C (113 °F). And then GO TO 2.
NO-2 [if it is above 45 °C (113 °F)]>>Cool the engine down to the val ue of âCOOLAN TEMP/Sâ indicates â5 °C
(23 °F) and 45 °C (113 °F). And then GO TO 2.
2.PERFORM DTC CONFIRMATION PROCEDURE-I
1. Turn ignition switch OFF and wait at 10 seconds.
2. Turn ignition switch ON.
3. Set the selector lever in N range.
4. Start the engine and let it idle for 20 seconds or more.
5. Check 1st trip DTC.
Is 1st trip DTC detected?
YES >> Proceed to EC-394, "Diagnosis Procedure"
NO >> INSPECTION END

2.CHECK VTC POSITION
With CONSULT
1. Turn ignition switch ON.
2. On the CONSULT screen, select âENGINEâ >> âDATA MONITORâ >> âCOOLAN TEMP/Sâ.
3. Check that the âCOOLAN TEMP/Sâ indication value is between â5 °C (23 °F) and 45 °C (113 °F).
4. Start engine and wait at least 5 seconds.
5. On the CONSULT screen, select âENGINEâ >> âDATA MONITORâ >> âINT/V TIM (B1)â.
6. Check that the data monitor item indicates as follows:
Is the inspection result normal?
YES >> Check intermittent incident. Refer to GI-43, "Intermittent Incident".
NO >> GO TO 3.
3.CHECK OIL PRESSURE WARNING LAMP
1. Start engine.
2. Check that oil pressure warning lamp is not illuminated.
Is oil pressure warning lamp illuminated?
YES >> Refer to LU-9, "Inspection".
NO >> GO TO 4.
4.CHECK INTAKE VALVE TIMING INTERMEDIA TE LOCK CONTROL SOLENOID VALVE
Perform Component Inspection of the intake valve timi ng intermediate lock control solenoid valve. Refer to
EC-397, "Component Inspection (Intake Valve Timing Intermediate Lock Control Solenoid Valve)"
.
Is the inspection result normal?
YES >> GO TO 5.
NO >> Repair or replace error-detected parts.
5.CHECK INTAKE VALVE TIMING CONTROL SOLENOID VALVE
