INSTALLATION
Install in the reverse order of removal.
CAUTION:
When replacing an engine or transmission you must make sure the dowels are installed correctly
during re-assembly.Improper alignment caused by mi ssing dowels may cause vibration, oil leaks or
breakage of drivetrain components.

INSPECTION AFTER INSTALLATION
Inspection for Leakage
The following are procedures for checking fluid leakage, lubricant leakage. Before starting engine, check oil/fluid levels includi ng engine coolant and engine oil. If any are less than the
required quantity, fill them to the specified level. Refer to MA-10, "
Fluids and Lubricants".
Follow the procedure below to check for fuel leakage.
- Turn ignition switch to the “ON” position (with engi ne stopped). With fuel pressure applied to fuel piping,
check for fuel leakage at connection points.
- Start engine. With engine speed increased, che ck again for fuel leakage at connection points.
Run engine to check for unusual noise and vibration. NOTE:
If hydraulic pressure inside chain tensioner drops af ter removal/installation, slack in guide may generate a
pounding noise during and just after the engine start. However, this does not indicate a malfunction. The
noise will stop after hydraulic pressure rises.
Warm up engine thoroughly to check that there is no leak age of fuel, or any oil/fluids including engine oil and
engine coolant.
Bleed air from lines and hoses of applic able lines, such as in cooling system.
After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill them to
the specified level, if necessary.

Diagnosis DescriptionINFOID:0000000006368066
AUTO ACTIVE TEST
Description
In auto active test, the IPDM E/R sends a drive signal to the following systems to check their operation.
Oil pressure warning lamp
Rear window defogger
Front wiper (LO, HI)
Parking lamp
License plate lamp
Tail lamp
Side marker lamp
Front fog lamp
Headlamp (LO, HI)
A/C compressor (magnet clutch)
Operation Procedure
CAUTION:
Never perform auto active test in the following conditions.
Engine is running.
CONSULT-III is connected.
1. Close the hood and lift the wiper arms from the windshield. (Prevent windshield damage due to wiper
operation)
NOTE:
When auto active test is performed with hood opened, sprinkle water on windshield beforehand.
2. Turn the ignition switch OFF.
3. Turn the ignition switch ON, and within 20 seconds, pr ess the driver door switch 10 times. Then turn the
ignition switch OFF.
CAUTION:
Close passenger door.
4. Turn the ignition switch ON within 10 seconds. Af ter that the horn sounds once and the auto active test
starts.
CAUTION:
Engine starts when ignition switch is turned ON while brake pedal is depressed.
5. The oil pressure warning lamp starts blinking when the auto active test starts.
6. After a series of the following operations is repeated 3 times, auto active test is completed.
NOTE:
When auto active test has to be cancelled halfw ay through test, turn the ignition switch OFF.
When auto active test is not activated, door swit ch may be the cause. Check door switch. Refer to DLK-117,
"ComponentFunctionCheck".
Inspection in Auto Active Test
When auto active test is actuated, the following operation sequence is repeated 3 times.
Operation
