8. If a new ignition key is registered further, repeat steps 1 to 7 above.
A maximum of eight ignition keys can be registered to one vehicle (If you
attempt to register the ninth key, the immobilizer-ECU rejects the key). If any
of the following conditions are satisfied, the additional key registration mode
will terminate:
The immobilizer indicator starts blinking for more than 30 seconds. After the ignition key has been turned to the "LOCK" (OFF), the engine
control relay is turned off. The scan tool has started communicating with vehicle systems.
9. After the registration mode has terminated, the additionally registered key(s)
should allow you to start the engine.
TRANSPONDER LOCK CHECK Required Special Tools:
MB991958: Scan Tool (MUT-III Sub Assembly)
MB991824: Vehicle Communication Interface (V.C.I.) MB991827: MUT-III USB Cable MB991910: MUT-III Main Harness A (Vehicles with CAN
communication system)
Follow the procedure below to judge if the ignition key can be overwritten (i.e. the
ignition key is correct) or not.
1. Connect the scan tool MB991958 to the data link connector. CAUTION: To prevent damage to scan tool MB991958, always
turn the ignition switch to "LOCK" (OFF) position
before connecting or disconnecting scan tool
MB991958.

GENERAL DESCRIPTION REMOTE CONTROLLED MIRROR OPERATION
The mirror glass on the remote controlled mirror moves up/down and left/right
by operating the remote controlled door mirror switch when the ignition switch
is in the "ON" or "ACC" position.
DOOR MIRROR HEATER OPERATION
The defogger relay switch is activated (ON) by turning on the A/C-ECU built-
in defogger switch when the ignition switch is in the "ON" position. When the
defogger relay is turned ON, power is supplied to the defogger and remote
controlled mirror, and the heater of the remote controlled mirror (heated door
mirror) starts operations. The defogger comes with a timer function and will
automatically turn OFF the switch approximately 11 minutes after the defogger
switch is turned ON. The door mirror heater operations are also terminated
along with the defogger, at this time.
HEATED DOOR MIRROR DIAGNOSIS TROUBLESHOOTING STRATEGY Diagnosis should be carried out by the following procedures.
1. Gather the information from the customer.
2. Verify that the condition described by the customer exists.
3. Find the malfunction by the following Symptom Chart.
4. Verify the malfunction is eliminated. TROUBLE SYMPTOM CHART TROUBLE SYMPTOM REFERENCE SYMPTOMS

CIRCUIT OPERATION
The TCL/ASC-ECU contains the power supply circuit (terminal 11) for the
solenoid valve. The solenoid valve is energized by the valve relay, which i
incorporated in the TCL/ASC-ECU. The valve relay, which is incorporated in the TCL/ASC-ECU, is always
energizing the solenoid valve unless the initial check is in progress when the
ignition switch is turned on. The TCL/ASC-ECU activates the solenoid valve by turning on its driving
transistor.
TCL/ASC DTC SET CONDITIONS These diagnostic trouble codes will be set under the cases below.
The solenoid valve is not energized even after the TCL/ASC-ECU has turned
on the driving transistor (Open circuit is present in the power supply circuit to
the TCL/ASC-ECU solenoid valve, or the valve relay has failed). The solenoid valve is not energized even after the TCL/ASC-ECU has turned
on the driving transistor (Open circuit is present in the solenoid valve circuit
inside the TCL/ASC-ECU, or the valve relay has failed). After the TCL/ASC-ECU has turned off the driving transistor, the solenoid
valve still remains energized (short in the solenoid valve circuit). When a solenoid valve failure is detected

CIRCUIT OPERATION
The TCL/ASC-ECU contains the power supply circuit (terminal 33) for the
pump motor. The pump motor is energized by the motor relay, which is
incorporated in the TCL/ASC-ECU. The motor relay, which is incorporated in the TCL/ASC-ECU, is always off
unless the motor solenoid valve check is activated when the vehicle is started. The TCL/ASC-ECU activates the pump motor by turning on the ECU built-in
motor relay when the ABS is working.
TCL/ASC DTC SET CONDITIONS These diagnostic trouble codes will be set under the cases below. DTC C1266: MOTOR SYSTEM (SEIZURE)
If the TCL/ASC-ECU determines that the pump motor is not running smoothly
(i.e. motor seizure) after the motor relay is turned off, this DTC will be set.
DTC C1273: MOTOR RELAY PROBLEM (STUCK OFF)
If the TCL/ASC-ECU determines that the motor is not running after the motor
relay is turned on, the ECU determines that the motor relay is stuck off, and
sets this DTC.
DTC C1274: MOTOR RELAY PROBLEM (STUCK ON)
If the TCL/ASC-ECU determines that the motor is running after the motor
relay is turned off, the ECU determines that the motor relay is stuck on, and
sets this DTC.
TROUBLESHOOTING HINTS (The most likely causes for these DTCs are to set are:)
CAUTION: If there is any problem in the CAN bus lines, an
incorrect diagnostic trouble code may be set. Prior to
this diagnosis, diagnose the CAN bus lines.
