FUNCTION DESCRIPTION:

This function allows the registration of a new Master Key even if all original Master Keys are lost. Once the Immobiliser system is reset, all previous registered keys will be erased. Use a new transponder Master Key to complete Transponder ECU Reset.

The Immobiliser Reset function is a 4-step process:
1. Using the Diagnostic Tester, retrieve a "Seed Number" through the OBD/MOBD Immobiliser function.
- A "Seed Number" is a unique number provided by the Diagnostic Tester and validated at TCI in order to return a Passcode.

2. Using the ETAS workstation, select Tools>Immobiliser Reset> Launch Immobiliser Reset, and complete the request form to retrieve a "Passcode Number."
3. A "Passcode Number" is a unique number required by the Diagnostic Tester to reset the ECU allowing it to accept a new Master Key.
- Enter the "Passcode Number" received from ETAS into the Diagnostic Tester, register any additional customer keys, and close auto registration mode.

4. Confirm successful Immobiliser reset and new Master Key registration.

PREPARATION: '01 RAV4

Before beginning the Key Code Reset function on 2001 MY RAV4 vehicles, it is necessary to short terminals T C to E 1 at the ECM connector, using SST No. 09843-18020. (Refer to Figure 1.)





With ECU connectors in place, back probe and short terminals T C to E 1 (pin 17 to pin 5).

NOTE:
- With the key ON and the engine OFF, the SRS, Cruise and ABS lights will flash on the instrument panel when terminals T C to E 1 are shorted together correctly.
- Leave the SST No. 09843 18020 in place for the entire Key Code Reset procedure.

KEY CODE RESET PROCEDURES:

NOTE:
Ensure that the Diagnostic Tester is equipped with the latest version of software (13.2a or later).

Connect the Diagnostic Tester to DLC3 and turn the ignition ON.





1. Using the Diagnostic Tester, follow the screen flow in Figure 2 to retrieve the "Seed Number." (DO NOT DISCONNECT the Diagnostic Tester from the vehicle during this process.).





2. Using the ETAS workstation, select Tools>Immobiliser Reset, and complete the request form to retrieve a "Passcode Number."
a. Click on Tools.
b. Click on Immobiliser Reset.





c. Read the instructions on the screen and click on Launch Immobiliser Reset. (See Figure 6.)





d. Complete the request form and enter the "Seed Number" from the Diagnostic Tester. Click on Submit. (Figure 5)

NOTE:
All fields must be completed.





e. ETAS will now return the Passcode that needs to be entered into the Diagnostic Tester.

NOTE:
The Passcode given by ETAS is only valid for one Immobiliser Reset Event.





3. Using the numbered keys (0-9) on the Diagnostic Tester, enter the "Passcode Number" received from ETAS into the Diagnostic Tester (see Figure 7). Press ENTER to clear all registered transponder codes except the Master key in the ignition cylinder.

NOTE:
- During the reset process do not remove the key from the ignition.
- This step takes approximately 16 minutes.

- Following a reset, the Transponder ECU is in auto registration mode.
- Auto registration mode allows 3 Master Keys and one Sub Key to register automatically.
- To register additional keys, remove the Master Key currently in the ignition. Insert keys (Master or Sub) into the ignition cylinder without turning the ignition on or off - simply insert and remove. (See Figure7, screen D.)

NOTE:
- If 4 keys are registered at this time, auto registration mode is automatically closed.
- If less than 4 keys are registered at this time, auto registration mode must be closed manually by cycling the ignition ON/OFF more than 5 times in 10 seconds. (See Figure 7, screen E.)
- If more than 4 keys need to be registered, use Transponder Code Registration (See TSB No. 1172).

4. Verify that keys are registered correctly by starting the engine with each newly registered key.

NOTE:
- If the vehicle starts, the new key code was registered correctly.
- If the vehicle does not start with any key, perform the Immobiliser Reset function again.
- If only one of the registered keys will not start the vehicle, attempt to register the key again following the Transponder Code Registration procedure explained in TSB No. 1172.

NOTE:
Issue of this Technical Service Bulletin is to ensure that proper repair information is available. IT DOES NOT CONSTITUTE AN AUTHORIZATION FOR REPAIR. Normal provisions of the formal warranty policy, as applicable, will apply.
