Keyless Entry Module: Adjustments
ETACS-ECU FUNCTION ADJUSTMENT PROCEDURE

The following functions can be adjusted by operating input swatches. The adjustments will be stored in the ECU memory even after a battery cable isdisconnected:

1. Entry conditions the adjustment mode
The ETACS-ECU sounds a tone alarm once when all of the following conditions are satisfied, and then enters the adjustment mode:-

Data link control: "ON" (Connect scan tool MB991502 or ground the data link connector No.1 terminal.)

2. Exit conditions from the adjustment mode
The ETACS-ECU cancels the adjustment mode when any of the following conditions is satisfied:-

Diagnosis control: "OFF" (Disconnect scan tool MB991502 or disconnect the data link connector No.1 terminal from the ground.)

- Key reminder switch: "ON" (Pull out the ignition key.)

3. Adjustment of functions

- Switching of keyless entry answerback function. (From activation to deactivation, or vice versa)

- Initialization the above function (From deactivation to activation)

- Key reminder switch: "OFF"

- Ignition switch: "OFF"

- Door switch: "OFF" (Close the door.)

-

If all of the conditions above are satisfied, the taillight switch will be turned on for more than .10 seconds

- Ignition switch: Other than "OFF"

- Door switch: "ON" (Open the door.)

-

3 minutes

After the ETACS-ECU has entered the adjustment mode, no adjustment is made within (If any adjustment is made within , the ETACS-ECU monitors a adjustment operation for other .)3 minutes 3 minutes

- Other warning tone alarm sounds

Keyless Entry Module: Procedures
HOW TO REGISTER SECRET CODE

Each individual secret code is registered inside the transmitter, and so it is necessary to resister these codes with the EEPROM inside the keyless entryreceiver-ECU in the following cases.

- When the transmitter or keyless entry receiver-ECU is replaced.

- If more transmitters are to be used.

- If it appears that a problem is occurring because of faulty registration of a code.

A maximum of two different code can be stored in the memory area of the EEPROM (two different transmitters can be used). When the code for thefirst transmitter is registered, the previously registered codes for two transmitters are cleared. Therefore, if you are using more than two transmitters orare adding a second transmitter, the codes for all the transmitters must be registered at the same time.

1. Check that the doors lock normally when the key is used.

To prevent damage to scan tool MB991502, always turn the ignition switch to the "LOCK" (OFF) position before connecting orCAUTION:

disconnecting scan tool MB991502.

2. Connect scan tool MB991502 to the data link connector (16-pin).

This will connect terminal (1) of the data link connector to ground, and the system will be in secret code registration standby mode.NOTE:

3. Within after connecting scan tool MB991502 turn the ignition switch to "ACC" for and then to "OFF" for ; repeat10 seconds 1 second 1 second

this procedure three times.

The doors will lock and unlock once at this time and the system will switch to registration mode.NOTE:

4. Press the transmitter switch, and then press it two times within of the first press. This will register the code.10 seconds

5. After registration is completed, the code will be automatically locked and unlocked once.

6. If you are using two transmitters or have added a second transmitter, the same registration procedure should be carried out for the second

one minute

transmitter, and it should be carried out within after registration of the code for the first transmitter has been completed. After thesecond registration is completed, the doors will be automatically locked and unlocked once.

7. Registration mode will be terminated under the following condition:

- When the secret codes for two transmitters have been registered.

-

When has passed after registration mode started.one minute

- When no secret codes have been registered for more than one minute after the registration mode is entered.

- If scan tool MB991502 is disconnected (ground is released).

- If the ignition switch is turned to "ON".

8. After registration mode has been completed, carry out the following to make sure that the keyless entry system operations.

- Pull the ignition key out.

- Close the all doors.

Condenser Fan Motor Relay: Testing and InspectionRelated Diagnostic Procedures
CIRCUIT OPERATION

- The battery positive voltage is applied on the ECM (terminal 21) from the condenser fan motor relay.

- When the ECM switches on its power transistor, the condenser fan motor relay coil is energized, causing current to flow in the circuit.

TROUBLESHOOTING HINTS

The most likely causes for this code to be set are:-

Malfunction of the condenser fan motor relay.

- Malfunction of the condenser fan motor.

- Improper connector contact, open circuit or short-circuited harness wire.

- ECM failed

CONNECTORS
DIAGNOSIS

STEP 1.

Check the circuit at ECM connector C-51.

ON

1. Disconnect connector C-51 and measure at the harness side.2. Turn the ignition switch "".3. Check the condenser fan condition.

- The fan should stop.

4. Measure voltage between terminal 21 and ground.

-

Voltage should be approximately (battery positive voltage)12 volts

5. Connect a jumper cable between 21 and ground.

- The fan should run.

If all checks above meet the specifications, go to STEP 2.If any check above does not meet the specifications, check the harness wire and connector between the ECM and A/C condenser fanmotor relay, and repair or replace if necessary. If the harness wire and connector is in good condition, check the A/C condenser fancircuit. Refer to Diagnosis. Then check that the malfunction is eliminated.

STEP 2.

Check harness connector C-51 at the ECM for damage.

If harness connector C-51 is not damaged, replace the ECM.If harness connector C-51 is damaged, repair or replace it.Refer to Harness Connector Inspection.Then check that the malfunction is eliminated.

NO: TSB-99-13-008 DATE: October, 1999MODEL: See below

SUBJECT:DTC P0120 DIAGNOSIS

This bulletin supersedes TSB-98-13-014, issued December, 1998. Mirage models have been deleted from this bulletin, as this condition can be correctedon 1.5L and 1.8L Mirages by reprogramming the PCM as described in TSB-99-13-007. The revised information is marked by "**".
PURPOSE

On some affected vehicles, the powertrain control module (PCM) may cause the "SERVICE ENGINE SOON" light to come on. Diagnostic TroubleCode DTC P0120 "Throttle Position Circuit Malfunction" may also set in the PCM.

If the PCM has previously been reprogrammed for this condition or if the vehicle was originally equipped with the latest PCM programming, perform thediagnosis instructions in Group 13 of the appropriate service manual for DTC P0120. If the PCM has not been previously reprogrammed and the TPSoperates normally, replace the PCM.
AFFECTED VEHICLES

1999 Montero Sport 2.4L models produced before 9/10/981999 Montero Sport 3.0L manual transmission models produced before 8/29/981999 3000GT SOHC and DOHC models produced before 8/25/981999 3000GT DOHC turbocharged (VR-4) models produced before 8/9/981999 Montero models produced before 8/25/98

:**IMPORTANT

This bulletin does NOT apply to 1.5L and 1.8L Mirage models. Refer to TSB-99-13-007 for PCM reprogramming instructions for these models.

:NOTE

This bulletin does not apply to 1999 Galant and Eclipse. Refer to TSB-98-13-013REV for these models.

PROCEDURE

1.
Using the MUT-II scan tool, check to see if any DTCs are set in the PCM. If any DTC except DTC P0120 is set, follow the appropriatetroubleshooting and repair instructions in the service manual. Then go to Step 2.

2. Inspect the underhood of the vehicle for an Engine Compartment label.
