2007 Lexus LS 460LFACTORY OEM SERVICE PROCEDURE

DTC Check / Clear

  1. CHECK DTC 
    1. DTCs which are stored in the TCM can be displayed on the intelligent tester or Techstream.

      The tester can display pending DTCs and current DTCs. Some DTCs are not stored unless a malfunction is detected in consecutive driving cycles. When a malfunction is detected in only one driving cycle, it is stored as a pending DTC.

      1. Connect the intelligent tester or Techstream to the DLC3.
      2. Turn the engine switch on (IG).
      3. Turn the tester ON.
      4. Enter the following menus:

        Intelligent tester 

        Select: DIAGNOSIS / OBD/MOBD / ECT / DTC INFO / CURRENT CODES.

        Techstream 

        Select: Powertrain / ECT / Trouble Codes.

      5. Confirm the DTCs and freeze frame data, and then write them down.
      6. Confirm the details of the DTCs (see DIAGNOSTIC TROUBLE CODE CHART  ).
        NOTE: When simulating a symptom with the scan tool to check for DTCs, use normal mode. For codes on the DIAGNOSTIC TROUBLE CODE CHART subject to "2 trip detection logic", perform the following actions. Turn the engine switch off after the symptom is simulated once. Then repeat the simulation process. When the symptom has been simulated twice, the MIL illuminates and the DTCs are recorded in the TCM.
  2. CLEAR DTC (using an intelligent tester or Techstream) 
    1. Connect the intelligent tester or Techstream to the DLC3.
    2. Turn the engine switch on (IG).
    3. Turn the tester ON.
    4. Enter the following menus:

      Intelligent tester 

      Select: DIAGNOSIS / OBD/MOBD / ECT / DTC INFO / CLEAR CODES.

      Techstream 

      Select: Powertrain / ECT / DTC / Clear.

  3. CLEAR DTC (without using an intelligent tester or Techstream)

      1. Disconnect the negative battery cable for more than 1 minute.
      2. Remove the EFI MAIN and ETCS fuses from the Engine Room No. 2 relay block, junction block located inside the engine compartment for more than 1 minute.
