ignition ACURA TL 1995 Service Manual PDF

Description

The car is equipped with the following devices to prevent inadvertent shifting:

Key cylinder with interlocked ignition key (Key Interlock System)

Shift lever with shift lock (Shift Lock System)

Key Interlock System:

When the shift lever is in any other position than or is not securely locked in (parking pin switch is ON), a solenoid is

activated, making it impossible to remove the ignition key from the ignition switch.

To be able to remove the key, the shift lever must be in and must be securely locked in this position (parking pin switch

must be turned off by the lock pin).

Troubleshooting (With Keyless Entry) ('98 model)

NOTE: The numbers in the table show the troubleshooting sequence.

CAUTION: To prevent damage to the motor, apply battery voltage only momentarily.

NOTE:

When the remote transmitter button is pressed the first time, only the driver's door will unlock. When the button is

pressed the second time, all the doors will unlock.

The doors will relock automatically after 20 seconds if a door is not opened, or the key is out of the ignition switch.

The keyless entry system will not lock the doors when the key is in the ignition switch.ProCarManuals.com

Remote Transmitter Replacement

Use the following procedure when replacing one or both

remote transmitters:

1. Open the driver's door.

2. Press and hold the driver's master door lock switch

up in the UNLOCK position.

3. Quickly insert and remove the key from the ignition

switch five times, then insert the key the sixth time,

and leave it in the ignition switch.

(This routine must be done within 10 seconds.)

All the doors will lock and unlock to indicate that

the control unit is in the program mode.

4. Press either button on the replacement transmitter.

All the doors except the driver's door will lock and

unlock to indicate that the control unit has accepted

the transmitter into its memory. If either transmitter

button is pressed again, all the doors will lock and

unlock.

5. To program a second transmitter, press either but-

ton on that transmitter. The doors should lock and

unlock as described in step 4.

6. Release the driver's master door lock switch.

7. To exit the program mode, close the driver's door

or remove the key from the ignition switch.ProCarManuals.com

SUPPLEMENTAL RESTRAINT SYSTEMThe Acura TL SRS includes a driver's airbag located in the steering wheel hub and a passenger's airbag located in the dashboard above
the glove box. Information necessary to safely service the SRS is included in this Service Manual. Items marked with an asterisk (*) on
the contents page include, or are located near, SRS components. Servicing, disassembling or replacing these items will require special
precautions and tools, and should therefore be done by an authorized Honda dealer.
WARNING

To avoid rendering the SRS inoperative, which could lead to personal injury or death in the event of a severe frontal
collision, all SRS service work must be performed by an authorized Honda dealer.

Improper service procedures, including incorrect removal and installation of the SRS, could lead to personal injury
caused by unintentional activation of the front airbags, seat belt tensioners, and side airbags ('99-01 models).

Do not bump the SRS unit. Otherwise, the system may fail in a collision, or the airbags may deploy when the ignition
switch in ON (II).

All SRS electrical wiring harnesses are covered with yellow insulation. Related components are located in the steering
column, front console, dashboard, dashboard lower panel, in the dashboard above the glove box. Do not use electrical
test equipment on these circuits.
NOTE: The original radio has a coded theft protection circuit. Be sure to get the customer's code number before
± disconnecting the battery.
± removing the No. 39 (10A) fuse from the under±hood fuse/relay box.
± removing the radio.
After service, reconnect power to the radio and turn it on. When the word ºCODEº is displayed, enter the customer's 5-digit code to restore
radio operation.
