BODY CONTROLS

Vehicles equipped with body, air conditioning, anti-lock brake or memory computers may require a computer relearn procedure after components are replaced or the vehicle battery is disconnected. Vehicle computers memorize and store vehicle information and operation selections. When the vehicle battery is disconnected, vehicle computer memory may be lost, requiring relearning or resetting. Depending on the vehicle and how it is equipped, the following memories may exist

  1. Seat position.
  2. Tilt/telescoping steering wheel position.
  3. Mirror position.
  4. Radio presets and anti-theft code.
  5. Clock.
  6. Remote keyless entry custom features.
  7. Door key lock entry custom features.
  8. Power window or sunroof operation.

These do not affect vehicle operation. For systems that do not affect operation, see appropriate article for relearn procedures. Other computer relearn procedures are required for vehicle or system operation. These may include

  1. Initial control unit programming.
  2. Traction control yaw sensor initializing.
  3. Multiplex communication.
  4. Anti-theft system or engine immobilizer system passwords.

ENGINE CONTROLS

Vehicles equipped with powertrain control computers may require a computer relearn procedure after the vehicle battery is disconnected. Vehicle computers memorize and store vehicle operation patterns for optimum driveability and performance. When the vehicle battery is disconnected, this memory is lost, which may result in a driveability problem. Depending on the vehicle and how it is equipped, the following driveability problems may exist

  1. Rough or unstable idle.
  2. Hesitation or stumble.
  3. Rich or lean running.
  4. Poor fuel mileage.
  5. Harsh or poor transmission/transaxle shift quality.

Default data is used until NEW data from each key start is stored. As the computer restores its memory from each new key start, driveability is restored.

Driveability problems may occur during the computer relearn stage. To accelerate computer relearn process after battery removal and installation, specified computer relearn procedures should be performed. See appropriate procedure.

SERVICE PRECAUTIONS (PRIUS)

WARNINGWhen performing any inspection or service procedure on this vehicle, ensure following service precautions are followed to prevent personal injury or death due to the extremely high voltage.

The following service precautions must be followed

  1. Ensure ignition is off and ignition key is removed from ignition before performing any inspection or service procedure in engine compartment, as engine may automatically start and shut off when ignition is on and READY light is illuminated. READY light is displayed just above the shift lever position indicator on instrument cluster at center of instrument panel.
  2. Read all service and warning labels in engine compartment before performing any procedures in engine compartment.
  3. All high-voltage wiring harness connectors contain Orange connectors. DO NOT touch any wiring harness that contains Orange connectors.
  4. High-voltage battery and other high-voltage components may be identified by HIGH VOLTAGE caution labels on them. DO NOT touch these components.
  5. If necessary to inspect or service high-voltage system, ensure ignition is off. Remove service plug and wait at least 5 minutes to ensure high voltage is fully discharged before touching any high-voltage wiring harness, connectors or components. Service plug is located on service plug assembly at driver's side front corner of trunk compartment, near high-voltage battery. (Scheme 1) Ensure service plug is stored in a location in which no one may install service plug while technician is working on the vehicle.
  6. If necessary to touch any high-voltage wiring harness, connectors or components, ensure service plug is removed and battery voltage or less exists at electrical connector. Use Toyota insulated gloves when touching any high-voltage wiring harness, connectors or components. Ensure insulated gloves are dry and in good condition and that no holes exist in insulated gloves. Test insulated glove by applying air to glove before touching any high-voltage wiring harness, connectors or components.
  7. DO NOT wear any metal objects while working on vehicle which may accidently drop and cause a short circuit.
  8. If any high-voltage wiring harness connector is disconnected, ensure terminal on wiring harness connector is wrapped with tape to prevent wiring harness connector from contacting any surface.
  9. If servicing high-voltage system, place sign on roof of vehicle to indicate to other technicians that high-voltage system is being serviced.

IMMOBILIZER PROGRAMMING (EXCEPT PRIUS)

Note. In the case of having lost all the already registered master ignition keys, you are not able to do additional registration or deletion of ignition key codes. You must change the Engine Control Module (ECM) and then perform ignition key registration.

IGNITION KEY REGISTRATION

Note. This procedure MUST BE performed ONLY when NEW Engine Control Module (ECM) is installed. A new ECM is in automatic registration mode. On Avalon, Camry Solara, Land Cruiser and MR2 up to 4 ignition key identification codes be may registered in the ECM at one time. On Camry models produced from January 2003 and later, Highlander and 4Runner, only up to 4 ignition key codes can be made: 3 master ignition key identification codes and 1 sub-key ignition key identification code may be registered in the ECM at one time. On Camry models produced before January 2003, RAV4, Sequoia and Sienna, up to 3 ignition key identification codes may be registered in the ECM at one time. For all models except Camry models produced after January 2003, Land Cruiser and 4Runner, in automatic registration mode, the last ignition key to be registered becomes the sub-key. For Camry models produced after January 2003 and 4Runner, the registration order is not specified because the transponder key ECU can distinguish keys types. On Land Cruiser, master and sub-key codes are registered automatically.

Note. A master key is a Black-colored ignition key and a sub-key is a Gray-colored ignition key.

  1. Ensure SECURITY indicator light is flashing. SECURITY indicator light is displayed as a vehicle icon near the center of the tachometer.
  2. Insert ignition key into ignition lock cylinder. Note that SECURITY indicator light should now remain on steady. On Camry models produced after January 2003, Land Cruiser, Sequoia and 4Runner models SECURITY indicator light should turn off when ignition key is inserted into ignition lock cylinder.
  3. On all models, once ignition key registration is under way, SECURITY indicator light should turn off. After ignition key registration is complete, SECURITY indicator light should come on steady. Remove ignition key.
  4. If ignition key registration was complete, and system is operating normally, SECURITY indicator light should flash when ignition key was removed from ignition lock cylinder. If ignition key registration was not completed with ECM in automatic registration mode, a code 2-1 will be displayed by SECURITY indicator light. (Scheme 2) When inserting an already registered ignition key, a code 2-2 will be displayed by SECURITY indicator light. (Scheme 2)
  5. If programming additional ignition keys, repeat process starting with step 1. If additional ignition keys do not need programming, procedure is complete. SECURITY indicator light should turn off once last ignition key (sub-key) is registered.
  6. On Avalon, Camry models produced before January 2003, Camry Solara and Highlander, to complete automatic registration mode, without removing or installing registered ignition key in ignition lock cylinder, depress and release brake pedal at least 5 times within 15 seconds, or request automatic registration mode completion by using Toyota hand-held tester connected to data link connector No. 3. Data link connector No. 3 is located at driver's side of instrument panel.
  7. On Camry models produced after January 2003 and 4Runner, to forcibly complete automatic registration mode when at least one key code for the master key has been registered turn ignition switch from ON position to OFF position 5 times within 10 seconds using the already registered master key.
  8. On Land Cruiser and Sequoia, to forcibly complete registration mode when at least one key code for the master key has been registered, turn ignition switch from the LOCK position to the ON position 5 times within 10 seconds using the already registered master key. If using hand-held tester, select automatic registration mode completion by using Toyota hand-held tester connected to data link connector No. 3. Data link connector No. 3 is located at driver's side of instrument panel.
