Precautions For PlasticsINFOID:0000000009464963
1. When repairing and painting a portion of the body adjacent to plastic parts, consider their characteristics
(influence of heat and solvent) and remove them if neces sary or take suitable measures to protect them.
2. Plastic parts should be repaired and painted using methods suiting the materials
, characteristics.

Diagnosis ProcedureINFOID:0000000009462152
1.CHECK FUSE
Check that the following fuse is not fusing.
Is the fuse fusing?
YES >> Replace the fuse after repairing the applicable circuit.
NO >> GO TO 2.
2.CHECK GROUND CONNECTION
1. Turn ignition switch OFF.
2. Check ground connection E9. Refer to GI-46, "Circuit Inspection"
.
Is the inspection result normal?
YES >> GO TO 3.
NO >> Repair or replace ground connection.
3.CHECK ECM GROUND CIRCUIT
1. Disconnect ECM harness connectors.
2. Check the continuity between ECM harness connector and ground.
*1: Except for California
*2: For California
Is the inspection result normal?
YES >> GO TO 4.
NO >> Repair or replace error-detected parts.
4.CHECK ECM POWER SUPPLY (MAIN)-1
1. Reconnect ECM harness connector.
2. Turn ignition switch ON.
3. Check the voltage between ECM harness connector terminals.

P0506 ISC SYSTEM
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 LogicINFOID:0000000009462307
DTC DETECTION LOGIC
NOTE:
If DTC P0506 is displayed with ot her DTC, first perform the trouble diagnosis for the other DTC.
DTC CONFIRMATION PROCEDURE
1.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.
If the target idle speed is ou t of the specified value, perform EC-179, "Work Procedure"
, before con-
ducting DTC Confirmation Procedure.
TESTING CONDITION:
• Before performing the following procedure, confirm th at battery voltage is more than 11 V at idle.
• Always perform the test at a temperature above −10 °C (14 °F).
>> GO TO 2.
2.PERFORM DTC CONFIRMATION PROCEDURE
1. Start engine and warm it up to normal operating temperature.
2. Turn ignition switch OFF and wait at least 10 seconds.
3. Start engine and run it for at least 1 minute at idle speed.
4. Check 1st trip DTC.
Is 1st trip DTC detected?
YES >> Proceed to EC-382, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis ProcedureINFOID:0000000009462308
1.CHECK INTAKE AIR LEAK
1. Start engine and let it idle.
2. Listen for an intake air leak after the mass air flow sensor.
Is intake air leak detected?
YES >> Discover air leak location and repair.
DTC No. CONSULT screen terms
(Trouble diagnosis content) DTC detecting condition Possible cause
P0506 ISC SYSTEM
(Idle air control system RPM lower
than expected) The idle speed is less than the target idle
speed by 100 rpm or more. • Electric throttle control actuator
• Intake air leak

3.PERFORM DTC CONFIRMATION PROCEDURE FOR MALFUNCTION B
1. Drive the vehicle for at least 5 consecut ive seconds as per the following conditions.
CAUTION:
Always drive vehicle at a safe speed.
NOTE:
This procedure may be conducted with the drive wheel s 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.
2. Check DTC.
Is DTC detected?
YES >> Proceed to EC-452, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis ProcedureINFOID:0000000009462379
1.CHECK OVERALL FUNCTION-1
With CONSULT
1. Turn ignition switch ON.
2. Select “BRAKE SW1” in “DATA MONI TOR” mode of “ENGINE” using CONSULT.
3. Check “BRAKE SW1” indication as per the following conditions.
Without CONSULT
1. Turn ignition switch ON.
2. Check the voltage between ECM harness connector terminals as per the following.
*1: Except for California
*2: For California
Is the inspection result normal?
YES >> GO TO 2.
