Land Cruiser URJ200 URJ202 GRJ200 VDJ200 - THEFT DETERRENT / KEYLESS ENTRY
ENGINE IMMOBILISER SYSTEM (w/o Entry and Start System) - DATA LIST / ACTIVE TEST
| DATA LIST |
- HINT:
Using the intelligent tester to read the Data List allows the values or states of switches, sensors, actuators and other items to be read without removing any parts. This non-intrusive inspection can be very useful because intermittent conditions or signals may be discovered before parts or wiring is disturbed. Reading the Data List information early in troubleshooting is one way to save diagnostic time.
If the ignition switch cannot be turned to ON, communication with the intelligent tester can be performed by connecting the intelligent tester to the vehicle and turning a courtesy light switch on and off at intervals of 1.5 seconds or less until communication between the intelligent tester and vehicle begins.
- NOTICE:
- In the table below, the values listed under "Normal Condition" are reference values. Do not depend solely on these reference values when deciding whether a part is faulty or not.
Connect the intelligent tester to the DLC3.
Turn the ignition switch to ON.
Turn the intelligent tester on.
Enter the following menus: Body / Immobiliser / Data List.
Enter the following menus: Powertrain / Engine and ECT / Data List.
According to the display on the intelligent tester, read the Data List.

Malfunctions in the key, transponder key ECU assembly or transponder key amplifier. |
| Different Encrypt Code*1 | Code status between transponder chip and transponder key ECU assembly / OK or NG | OK: Codes of transponder chip and transponder key ECU assembly match NG: Codes of transponder chip and transponder key ECU assembly do not match | Problems may be caused by the following: A key from a different vehicle is being used. Malfunctions in the key, transponder key ECU assembly or transponder key amplifier. |
| Abnormal Status*1 | Transponder chip status signal / OK or NG | OK: Transponder chip status signal normal NG: Transponder chip status signal malfunction (malfunction in code computation in key/transponder key ECU assembly) | Problems may be caused by the following: Communication errors due to external electric wave noise (LF). Malfunctions in the key, transponder key ECU assembly or transponder key amplifier. |
| Bcc Malfunction*1 | BCC signal status of transponder chip / OK or NG | OK: BCC signal normal NG: BCC signal malfunction (malfunction in code computation in key/transponder key ECU assembly) | Problems may be caused by the following: Communication errors due to external electric wave noise (LF). Malfunctions in the key, transponder key ECU assembly or transponder key amplifier. |
| Sub Key | Whether sub-key ID code matches ID code registered in transponder key ECU assembly / Reg or Unreg | Reg: ID code of sub-key matches ID code registered in transponder key ECU assembly Unreg: ID code of sub-key does not match ID code registered in transponder key ECU assembly | - |
| Master Key | Whether master key ID code matches ID code registered in transponder key ECU assembly / Reg or Unreg | Reg: ID code of master key matches ID code registered in transponder key ECU assembly Unreg: ID code of master key does not match ID code registered in transponder key ECU assembly | - |
| Transponder S-code | Number of registered sub-keys / min.: 0, max.: 3 | Number of registered sub-keys | - |
| Transponder M-code | Number of registered master keys / min.: 0, max.: 5 | Number of registered master keys | - |
| Reg Code Space Full | Key registration code memory space full / Yes or No | No: Possible to register more key codes Yes: Cannot register any more key codes | - |

- HINT:
*1: This indicates that there is a problem with the communication format between the key and transponder key ECU assembly. Electric wave interference, key or transponder key ECU assembly malfunctions, the key of another vehicle being used, etc. are possible causes.
*2: Refer to the following Data List items of an actual vehicle.
*1: Without depressing the brake pedal (for Automatic Transaxle) or clutch pedal (for Manual Transaxle), insert the key into the ignition key cylinder and turn the ignition switch to ACC.
*2: Without depressing the brake pedal (for Automatic Transaxle) or clutch pedal (for Manual Transaxle), turn the ignition switch to ON.
*3: Turn the ignition switch off and remove the key from the ignition key cylinder.

| ACTIVE TEST |
- HINT:
- Using the intelligent tester to perform Active Tests allows relays, VSVs, actuators and other items to be operated without removing any parts. This non-intrusive functional inspection can be very useful because intermittent operation may be discovered before parts or wiring is disturbed. Performing Active Tests early in troubleshooting is one way to save diagnostic time. Data List information can be displayed while performing Active Tests.
Connect the intelligent tester to the DLC3.
Turn the ignition switch to ON.
Turn the intelligent tester on.
Enter the following menus: Body / Immobiliser / Active Test.
Perform the Active Test according to the display on the intelligent tester.
