BODY ELECTRICAL SYSTEM

BODY ELECTRICAL BODY ELECTRICAL SYSTEM PRECAUTION BODY ELECTRICAL SYSTEM Carefully to observe the following precautions when servicing the parts related to the body electrical system. 1. LIGHTING SYSTEM Halogen bulbs have pressurized gas inside and require special handling. They can burst or scatter if scratched or dropped. Hold a bulb only by its plastic or metal case. Do not touch the glass part of a bulb with bare hands. 2. SRS (SUPPLEMENTAL RESTRAINT SYSTEM) The TOYOTA TUNDRA is equipped with the Supplemental Restraint System (SRS) (for example, the driver airbag). Failure to carry out service operations in the correct sequence could cause the SRS to unexpectedly deploy during servicing, possibly leading to a serious accident. Before servicing (including removal, installation, inspection and replacement), be sure to read the precautionary notices in the RS section. 3. AUDIO SYSTEM If the battery negative () terminal is disconnected, the preset AM, FM 1 and FM 2 stations stored in the memory are erased. Be sure to make a note of the stations and reset them after the battery terminal is reconnected. 4. MOBILE COMMUNICATION SYSTEM If the vehicle is equipped with a mobile communication system, refer to the precautions for the mobile communication system in the IN section. BE1 BE01E11 4558

SELECTING COMPASS DISPLAY MODE The mode select switch allows you to select the Display or Nondisplay mode of the compass. 2. SETTING ZONE Deviation between the magnetic north and actual north differs depending on the terrestrial location. Therefore, adjustment of the magnetism is required. Since the magnetic condition differs depending on the area where the vehicle is used, it is necessary for each user to set the zone. (Refer to Compass Zone Map). The zone setting can be changed using the E/M switch of the display. 3. PERFORMING CALIBRATION Because each vehicle has its own magnetic field, calibration should be performed for each vehicle. This compass function is used when storing the record of the vehicle s magnetic field. 4. WHEN COMPASS MAGNETIZED: A compass could be magnetized during shipping by vessels or freight cars. Therefore, make sure to perform calibration and ensure that calibration is performed properly before delivery. If it cannot be done (cannot complete in spite of driving round several times), it may be caused by magnetization. Demagnetize the vehicle using a demagnetizer and perform calibration again. 5.

BODY ELECTRICAL COMPASS (Double Cab) BE101 HINT: In the initial status, 8 is displayed. (c) The displayed number increases +1 every time the E/M switch is pressed. Referring to the map, check the number for the area where the vehicle will be used and set the zone number. (d) Leave it untouched for several seconds after setting and check that the compass display shows an azimuthal direction (N, NE, E, SE, S, SW, W, or NW) or VAR. 7. CALIBRATION SETTING MODE (a) After the set zone is displayed, if the E/M switch and MODE switch remains pressed another 5 seconds will activate the calibration setting mode. (b) To keep pressing the E/M switch and MODE switch for 10 seconds when outer temperature is displayed will also activate this mode. (c) Drive the vehicle at a slow speed of 8 km/h (5 mph) or less in the circular direction. (d) Driving round the circle 1 to 3 times will display the azimuthal direction on the display, completing the calibration. HINT: After the calibration is completed, it is not necessary to perform the above procedures unless the magnetic field strength is drastically changed. If this happens, the azimuthal display will be changed to CAL. 4658

BODY ELECTRICAL Indicator I27622 GARAGE DOOR OPENER SYSTEM (Double Cab) BE203 GARAGE DOOR OPENER SYSTEM (Double Cab) REGISTRATION PROCEDURE REGISTER TRANSMITTER CODE HINT: BE2KG01 The vehicle s garage door opener records transmitter codes for systems such as garage doors, gates, entry gates, door locks, home lighting systems, security systems or other transmitter code based systems. The garage door opener is built into the roof console box assembly. After the console box assembly is replaced, transmitter codes for any systems previously registered in the garage door opener must be reregistered. (a) Reregister systems in the garage door opener registration mode. NOTICE: Do not perform transmitter code registration for a system if people or objects are near the system to be registered. When registering transmitter codes, injury or damage can occur as the system may open, close, unlock or otherwise operate. Before transmitter code registration, stop the engine and remove the key from the ignition switch. The garage door opener cannot be used with: 1) systems that: 1) were manufactured before April 1, 1982; or 2) systems that do not meet Federal Safety Standards (for example, garage doors without a jam protection function). HINT: 3 transmitter codes can be registered with the garage door opener, one transmitter code for each of the 3 garage door opener switches. Disconnecting the battery will not erase the transmitter codes registered with the garage door opener. An attempt to overwrite a previously registered transmitter code with a new system s transmitter code may fail. In these situations, the previously registered transmitter code will not be erased. 4760

BE204 BODY ELECTRICAL GARAGE DOOR OPENER SYSTEM (Double Cab) Indicator I27622 (1) Select a switch of the garage door opener for the transmitter code registration. (2) Press and hold the selected switch for 20 seconds. Then, the garage door opener enters registration mode. HINT: Before entering registration mode, the indicator shows the display. After entering registration mode, the indicator flashes at a cycle of 1 Hz. For a rolling code type system, after entering registration mode, the indicator flashes at a cycle of 8.8 Hz for 1.6 seconds, and then the indicator flashes at a cycle of 1 Hz. Original Transmitter Press I18598 (3) After the garage door opener has entered registration mode, bring the original transmitter of the system to be registered within 1 to 3 inches of the garage door opener and press and hold one of the garage door opener switches. Then press the original transmitter switch. (4) If the transmitter code registration was successful, the indicator of the garage door opener flashes at a cycle of 5.6 Hz. If no malfunction occurs, release both the garage door opener switch and the original transmitter switch. HINT: If transmitter code registration fails: 1) the original transmitter s battery may be low or need to be replaced, or 2) the system to be registered may not be compatible with the garage door opener. Some transmitter s signals stop after 1 to 2 seconds. For these types of transmitters: 1) press and hold one of the garage door opener switches, and 2) press and release (cycle) the transmitter switch every 2 seconds. Check if the transmitter code was successfully registered. After entering the garage door opener registration mode, transmitter code registration must be completed within 90 seconds. If 90 seconds elapses, the garage door opener will enter low power mode (See step (c)). 4761
