CAUTION:
Always drive at a safe speed.
NOTE:
•If DTC P0011 is displayed with DTC P0075, first perform trouble diagnosis for DTC P0075.
See EC-659
.
• If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait at
least 10 seconds before conducting the next test.

2. Start engine and warm it up to the normal operating temperature.
3. Maintain the following conditions for at least 6 consecutive seconds. Hold the accelerator pedal as steady as possible.
4. Let engine idle for 10 seconds.
5. If 1st trip DTC is detected, go to EC-647, "
Diagnosis Procedure".
If 1st trip DTC is not detected, go to next step.
6. Maintain the following conditions for at least 10 consecutive seconds.
7. If 1st trip DTC is detected, go to EC-647, "

NOTE:
If DTC P0506 is displayed with ot
her DTC, first perform the trouble diagnosis for the other DTC.
The ECM controls the engine idle speed to a specified level 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 id ling speed. The ECM calculates the actual engine speed
from signals of crankshaft position sensor (POS) and camshaft position sensor (PHASE).
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 load (air conditioner, power steering and cooling fan
operation, etc.).

General PrecautionsINFOID:0000000005931064
Observe the following precautions when disassembling and assembling drive shaft.
• Joint sub-assembly does not disassemble because it is non-overhaul parts.
• Perform work in a location which is as dust-free as possible.
• Before disassembling and assembling, clean the outside of parts.
• Prevention of the entry of foreign objects must be tak en into account during disassembly of the service loca-
tion.
• Disassembled parts must be carefully reassembled in the correct order. If work is interrupted, a clean cover must be placed over parts.
• Paper shop cloths must be used. Fabric shop cloths must not be used because of danger of lint adhering to
parts.
• Disassembled parts (except for rubber parts) should be cleaned with kerosene which shall be removed by blowing with air or wiping with paper shop cloths.

Precaution for Liquid GasketINFOID:0000000005928696
REMOVAL OF LIQUID GASKET SEALING
• After removing nuts and bolts, separate the mating surface, using Tool and remove old liquid gasket sealing.
CAUTION:
Be careful not to damage the mating surfaces.
• Tap Tool to insert it (1), and then slide it by tapping on the side (2) as shown.
• In areas where Tool is difficult to use, use plastic hammer to lightly tap the parts, to remove it.
CAUTION:
If for some unavoidable reason suitable tool such as screw-
driver is used, be careful not to damage the mating surfaces.
LIQUID GASKET APPLICATION PROCEDURE
1. Remove old liquid gasket adhering to the liquid gasket applica- tion surface and the mating surface, using scraper.
• Remove liquid gasket completely from the groove of the liquidgasket application surface, bolts, and bolt holes.
2. Thoroughly clean the mating surfaces and remove adhering moisture, grease and foreign materials.
3. Attach liquid gasket tube to Tool.
Use Genuine RTV Silicone Seal ant or equivalent. Refer to GI-42, "
Recommended Chemical Prod-
uct and Sealant".
4. Apply liquid gasket without breaks to the specified location with the specified dimensions. • If there is a groove for the liquid gasket application, apply liquid gasket to the groove.
• As for the bolt holes, normally apply liquid gasket inside theholes. Occasionally, it should be applied outside the holes.
Make sure to read the text of service manual.
• Within five minutes of liquid gasket application, install the mat-
ing component.
• If liquid gasket protrudes, wipe it off immediately.
• Do not retighten nuts or bolts after the installation.
• After 30 minutes or more have passed from the installation, fill engine oil and engine coolant.
CAUTION:
If there are specific instructions in this manual, observe them.
