•

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

A maximum of four different codes can be stored in the
EEPROM memory (four different transmitters can be used).
When the code for the first transmitter is registered, the
previously registered codes for all transmitters are cleared.
Therefore, if you are using four transmitters or are adding more
transmitters, the codes for all transmitters must be registered at
the same time.
1. Check that the doors lock normally when the key is used.

2. Insert the ignition key.

CAUTION

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

3. Connect the scan tool to the data link connector. If the scan

tool is not used, ground terminal (1) of the data link
connector.

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

4. Press the hazard switch six times within 10 seconds.

NOTE: At this time the code registration monitor request is
output (all doors locked and unlocked) and becomes
registration mode.

NOTE: The hazard warning light switch is turned on and off
alternately whenever it is pushed.

5. Press the transmitter switch, and then press it two times

within 10 seconds of the first press. This will register the
code.

6. When registration is completed, the code registration

monitor request is output (all doors locked and unlocked).

7. If you are using two or more transmitters or have added a

second transmitter, the same registration procedure should
be carried out within one minute after registering the code
for the first transmitter. After the second registration is
completed, the code registration monitor request is output
(all doors locked and unlocked).

8. Registration mode will be canceled under the following

conditions:

SUNROOF DIAGNOSIS

INTRODUCTION TO SUNROOF DIAGNOSIS

M1426003100039

The operation of the sunroof is controlled by the
sunroof-ECU. By operating the sunroof switch, the
sunroof-ECU rotates the sunroof motor. If the
following type of symptom occurs, there may be a
fault

•

The sunroof motor does not conduct load
detection operation.

•

The illumination light of the sunroof switch does
not illuminate.

•

The sunroof does not operate.

SUNROOF DIAGNOSTIC TROUBLESHOOTING STRATEGY

M1426001700024

Use these steps to plan your diagnostic strategy. If
you follow them carefully, you will be sure that you
have exhausted most of the possible ways to find a
sunroof fault.
1. Gather information from customer.

2. Verify that the condition described by the

customer exists.

3. Find the malfunction by following the Symptom

Chart.
