WARNING: This page is about a different car, the 2003 Toyota Sequoia. However, it is still accessible from the selected car via links, so may be relevant.
  1. DIAGNOSIS SYSTEMΒ 
    1. Description

      ECM controls the function of the cruise control on a vehicle.

      Data on the cruise control and on the DTC can be read from the DLC3 on the vehicle. If CRUISE MAIN indicator does not comes on after the DTC check, there is a malfunction on the cruise control.

      Use the hand-held tester or SST to check and solve the problem.

    2. Check the DLC3.

      The vehicle's ECM uses ISO 9141-2 for communication. The terminal arrangement of DLC3 complies with SAE J1962 and matches the ISO 9141-2 format.

      TERMINAL CONDITION

      Terminal No. Connection/Specified Condition Condition
      4 Chassis Ground <--> Body Ground / 1 Ξ© or less Always
      7 Bus(+)Line / Pulse Generation During Communication
      16 Battery Positive <--> Body Ground / 9 - 14 V Always
      NOTE: If the display shows "UNABLE TO CONNECT TO VEHICLE" as connecting the TOYOTA hand-held tester to the DLC3 and turn the ignition ON, there is a problem either on the vehicle or on the tool.
      • If communication is normal when connecting the tool to another vehicle, inspect DLC3 on the original vehicle.
      • If communication is still not possible when connecting the tool to another vehicle, the problem is probably in the tool itself. Consult the Service Department listed in the tool's instruction manual in that case.
    3. Check the indicator.
      1. Turn the ignition switch to ON.
      2. Check that the CRUISE MAIN indicator light comes ON when the cruise control main switch is turned ON, and that the indicator light goes off when the main switch is turned OFF.
