Introduction

If an owner pauses while turning the ignition key and the ignition switch is between the ACC position and the ON position (IG1 is ON and IG2 is OFF), the Lexus Link ECU will start up but the SRS system will not have power. The Lexus Link system receives its start-up signal from IG1 and the SRS system receives its power supply from IG2. The Lexus Link ECU will assume that there is a fault in the connection between the Lexus Link ECU and the SRS system and the Lexus Link ECU will announce: "A Lexus Link system error has been detected." Also, an automatic emergency call or service call may be made to the Lexus Link call center. To address this issue, an additional wiring harness has been developed.

How to Check if the Lexus Link System Is Functioning
1. Performing the check when the ignition switch is turned ON (Reference):
  1. Turn the ignition switch OFF and turn it ON again. Start the engine. Three possible audio messages can be output from the vehicle depending on the status of the Lexus Link system.
    1. If the customer has a current Lexus Link subscription (Active Mode), an English message will play:
      "The Lexus Link system is active."
    2. If the customer has an expired Lexus Link subscription (Dealer Mode), an English message will play:
      "The Lexus Link system is not active. To activate your Lexus Link system, press the Service button now."
    3. If the Lexus Link system is initial mode* (Factory Mode), a Japanese message (with a female voice) will play:
      (You will hear a Japanese message with female voice.)
      
      * Mode has not been switched yet.
  2. Wait for 30 seconds. Listen for error messages.
2. Performing the diagnosis check (check before and after servicing the Lexus Link system).
  1. Turn the ignition switch OFF.
  2. Press and hold the "play" button or the "volume up" button. With the button pressed, turn the ignition switch ON, OFF, ON, OFF and then ON within 15 seconds.
    - If the voice message, "System OK," is confirmed, there is no problem with the Lexus Link system.
    - If an error message is heard, refer to the service manuals.
3. Turn the ignition switch to LOCK.
  NOTE: CAUTION BEFORE DISCONNECTING THE NEGATIVE BATTERY TERMINAL: Turn the ignition switch to the LOCK position and wait for approximately 30 seconds. Then, disconnect the negative (-) terminal cable from the battery and wait for 90 seconds. Then you may start working on the vehicle. Disconnecting the negative (-) terminal cable within 10 seconds after the ignition switch is turned to the LOCK position will activate the Lexus Link system using the back-up battery and cause the system to make an emergency call. Working on the vehicle within 90 seconds after the negative (-) terminal cable is disconnected may deploy the SRS using the SRS's back-up power source.
4. Disconnect the negative (-) terminal cable from the battery.
