^ If all the lash adjusters are found to be normal after the simple lash adjuster check (all rocker
arms are hard to push down), check for other causes for the abnormal noise.

NOTE
The lash adjuster can also be checked correctly by using the leak down test found in the particular

service manual (Group 11 - Rocker Arm and Camshaft) for the vehicle being diagnosed.
CAUTION
Be sure to bleed the air from a new valve lash adjuster before installing it. For lash adjuster air

bleeding procedures, refer to the air bleeding procedures elsewhere in this bulletin or in the proper
service manual, (Group 11 - Rocker Arm and Camshaft).

7. Start the engine and make sure the abnormal noise is gone. Make sure to do the air bleeding
operation.

8. On DOHC engines, replace the lash adjusters using the following procedures.
CAUTION
Before removing the lash adjuster, turn the crankshaft to lower the piston of the cylinder being

checked. Otherwise the valve will contact the piston when the valve is pushed down for checking.
In addition, the lash adjuster cannot be removed at the rocker arm lifted by the cam. In this case,

turn the crankshaft so the rocker arm in question is not being lifted by the cam.
a. Use the special tool shown in the service manual to push down the valve and remove the roller

rocker arm.
b. Pull out the lash adjuster from the cylinder head.
c. Bleed the air from the new adjuster and install it into the cylinder head.

SERVICE MANUAL REVISION
The engine troubleshooting chart in the service manuals for all affected models requires one

revision concerning the symptom of "Noisy valves". Make the change to all affected manuals as
shown.

PROCEDURES
Lash Adjuster Noise Check
If an abnormal noise (chattering or clicking noise), suspected to be a malfunctioning lash adjuster,

is produced immediately after starting the engine and does not go away, perform the following
checks:

NOTE: (1)
An abnormal noise caused by a malfunctioning valve lash adjuster is produced immediately after

starting the engine and changes with the engine speed, no matter what the engine load.
Therefore, if abnormal noise is not apparent just after starting the engine, if it does not change with

engine speed, or if it changes with engine load, the noise is not caused by a malfunctioning lash
adjuster.

Wastegate Solenoid: Description and Operation

PURPOSE/OPERATION
The wastegate solenoid valve is an electromechanical, vacuum switching valve the allows the

engine control module to reduce boost pressure. This is to maintain optimum boost pressure under
all driving conditions and prevent engine damage during component failures or detonation. The
wastegate solenoid is spring loaded in the closed (lowest boost) position until after the engine is
started. The solenoid is powered by the control relay. The engine control module completes the
circuit to ground (highest boost) while the engine is running. When the solenoid is energized, boost
pressure to the wastegate actuator is bled back to the air filter housing and the wastegate stays
closed. When the engine control module detects detonation or sensor failure, the ground circuit is
interrupted, solenoid turns off and full manifold pressure is applied to the wastegate.

The engine control module uses the following vehicle load condition inputs to regulate the on off
signal to the solenoid: -

Detonation sensor

- Air flow sensor

- Engine RPM

- Barometric pressure sensor

- Intake air temperature sensor
The engine control module does not control boost pressure it only regulates it during failures of the

control components.

Ignition Switch - Key Difficult to Remove

Shift Cable: All Technical Service Bulletins Ignition Switch - Key Difficult to Remove
No: TSB-97-23-006 Date: June, 1997 Model: See below
SUBJECT: IGNITION KEY DIFFICULT TO REMOVE
PURPOSE The ignition key may be difficult to remove when the shift lever is returned to the "P"

position, especially in cold ambient temperatures. This bulletin describes how to improve ignition
key interlock performance by installing an A/T shifter control cable kit.

BACKGROUND INFORMATION
The ignition key interlock cable keeps constant pressure on the key lock cam when the shift lever is

in either the "R", "N", "D", "2", or "L" position. When the shift lever is moved to the "P" position, the
constant pressure on the key lock cam may bind the detent pin, not allowing it to return to the "P",
position. This condition causes the ignition key to be difficult to remove.

An A/T shifter control cable kit is now available with a rubber washer on the shifter lever side.
When the shift lever is in the "P" position, the rubber washer creates a backward pressure on the
shift lever to allow the detent pin to move more freely. The detent pin motion can now rotate the
key lock cam, and the ignition key can be easily removed.

AFFECTED VEHICLES
^ 1995-96 Eclipse automatic transaxle models equipped with 2.0L turbocharged engine
^ 1995-96 Eclipse Spyder automatic transaxle models equipped with 2.0L turbocharged or 2.4L

engine
^ 1994-96 Galant automatic transaxle models
PROCEDURE

1. Follow the instructions in Group 23 of the appropriate service manual to remove the NT shift
interlock cable.

If (B) is less than 2.4 mm, remove the clamp, readjust (W) on the tool as shown in Step 5 using the
following formula. Then, install a new clamp and repeat Steps 6 and 7.

W = 5.5 - B Example: When (B) = 2.3, then 5.6 - B (2.3) = W (3.2)
You would adjust the tool (W) dimension to 3.2 mm, then crimp the newly installed clamp.

9. After crimping the clamp, make sure it is seated into the proper recess in the boot, and is not
covering any other area on the boot. If it is not in the proper place, remove it and install another
clamp by repeating Steps 6 through 8.

10. Fill the boot with the specified amount of grease provided with the boot kit.

11. Install the large end of the boot onto the BJ housing so the clearance (C) between the boot and
the stepped portion of the housing is 0.1 to 1.55 mm.

12. Rotate the adjustment screw on the special tool so the clearance stop opening dimension (W
on the illustration) is 3.2 mm.

NOTE:
If (W) is more than 3.2 mm, turn the adjustment screw clockwise. If (W) is less than 3.2 mm, turn

the screw counterclockwise.

Garage Door Transmitter - Reprogramming Procedure

Garage Door Opener Transmitter: Technical Service Bulletins Garage Door Transmitter ­Reprogramming Procedure

NO.: TSB-97-00-003
DATE: April, 1997
MODEL: See below
SUBJECT: HOMELINK(R) ROLLING CODE PROGRAMMING
PURPOSE The HomeLink(R) Universal Transmitter system is available as optional equipment on

affected vehicles. Refer to TSB-96-00-001, issued January, 1996 for details on the HomeLink(R)
system. This bulletin describes how to reprogram the HomeLink® transmitter for a garage door
opener with a rolling code system.

Rolling codes change the code of a garage door opener every time the garage door is opened or
closed. Rolling codes give an added level of security by changing the transmitter and receiver code
every time they are activated. This makes it impossible to open the garage door using a copied
transmitter signal.

BACKGROUND INFORMATION
Garage door openers with a rolling code system have been manufactured since 1995. They will

appear to program the HomeLink(R) Universal Transmitter, but will not activate the garage door
until programmed as described in this bulletin.

Serial and rolling values are programmed into the original transmitter during production. The
receiver learns the transmitter's values when the garage door opener is installed. Garage door
openers with a rolling code system typically have a unique fixed serial number that is paired with a
rolling value that changes every time the transmitter button is pressed. The rolling value is from a
range of approximately 65,500 values. The transmitted value changes with each press of the
transmitter button. There is no distinguishable pattern to allow predicting future values.

When the transmitter is activated, it goes through a coding routine which varies depending on the
garage door opener manufacturer. The receiver can then decode the incoming value it receives
from the transmitter. It checks the serial number and rolling value. if they match, the receiver
activates the garage door opener. On rolling code garage door openers, the receiver locks out
rolling values that have already been used (which may have been copied).

AFFECTED VEHICLES
^ 1995-97 Galant
^ 1996-97 Eclipse
^ 1995-97 3000GT Spyder
^ 1997 Diamante
PROCEDURE
To program a garage door opener with a rolling code system to recognize the HomeLink(R)

Universal Transmitter:

1. First program the transmitter to learn the garage door opener's transmitter. Refer to TSB-00-001,
issued January, 1996 for details on HomeLink(R) memory programming.

2. Press the training button on the garage door opener receiver for one to two seconds. (The
location and color of the button may vary depending on the manufacturer.)

3. Press the programmed HomeLink(R) button for the duration of the rapid flash, until the training
light turns solid (about two seconds).

4. Release the HomeLink(R) button and press it again to complete the programming.
The HomeLink(R) Universal Transmitter can now be used to activate the garage door with rolling

codes.
For assistance in programming the HomeLink(R) Universal Transmitter, call HomeLink(R)

Bleeding Air From The Lash Adjuster System
NOTE ^
Parking the vehicle on a grade for a long time may decrease the amount of oil in the lash adjuster,

causing air to enter the high pressure chamber when starting the engine
^ After parking for many hours, oil may run out from the oil passage and take time before oil is

supplied to the lash adjuster, causing air to enter the high pressure chamber.
^ In the above cases, abnormal noise can be eliminated by bleeding the air from the lash adjuster

system.

1. Check the engine oil and add or change as necessary.
