Note
The cause of a malfunction is stored in the RAM or EEPROM in the certification ECU (smart key ECU assembly). As the cause of a malfunction stored in the RAM will be cleared when the cable is disconnected from the negative (-) battery terminal, do not disconnect the cable from the negative (-) battery terminal before checking and recording the operation history.
When using the GTS with the engine switch off, connect the GTS to the DLC3 and turn a courtesy light switch on and off at intervals of 1.5 seconds or less until communication between the GTS and the vehicle begins. Then select Model Code "KEY REGIST" under manual mode and enter the following menus: Body Electrical / Entry&Start(CAN). While using the GTS, periodically turn a courtesy light switch on and off at intervals of 1.5 seconds or less to maintain communication between the GTS and the vehicle.

| Parameter Name | Content |
|---|---|
| Transponder Key Amp Error | Although an unregistered electrical key transmitter sub-assembly was held near the engine switch, electrical key transmitter sub-assembly registration was not successful after one or more ID codes had successfully been registered due to a malfunction of the immobiliser amplifier, such as a short to ground. The ECU code was registered successfully. DTC B278A was stored. |
| Registration Failed; Vehicle ID Error | Although an unregistered electrical key transmitter sub-assembly was held near the engine switch, electrical key transmitter sub-assembly registration was suspended after one or more ID codes had successfully been registered because time had expired due to the vehicle ID code sent by the electrical key transmitter sub-assembly not matching the code stored by the certification ECU (smart key ECU assembly). A recognition code is used between the electrical key transmitter sub-assembly and the certification ECU (smart key ECU assembly). Although the vehicle ID stored in the certification ECU (smart key ECU assembly) should be registered to the electrical key transmitter sub-assembly when the electrical key transmitter sub-assembly was registered, it was not. "Registration Failed; Vehicle ID Error" is displayed when trying to register an electrical key transmitter sub-assembly of another vehicle. If electrical key transmitter sub-assembly registration could not be completed successfully after trying to register another electrical key transmitter sub-assembly, the certification ECU (smart key ECU assembly) might be malfunctioning. |
