INTRODUCTION

Some 2007 - 2012 model year LS 460 and LS 600h vehicles may exhibit a hesitation on acceleration feeling due to inappropriate spark knock or detonation detection, and in some cases set Diagnostic Trouble Code (DTC) P2119 (Throttle Actuator Control Throttle Body Range/Performance). To enhance the smoothness of acceleration, the Engine Control Module/ECM (SAE term: Powertrain Control Module/PCM) calibration has been revised. In some instances, replacement of the cylinder heads may also be required. Use the REPAIR PROCEDURE  in this bulletin to address this condition.

DIAGNOSTIC PROCEDURE

NOTE:
  • ONLY complete the Diagnostic Procedure if the cylinder heads were NOT previously replaced per original L-SB-0038-08.
  • If cylinder heads were previously replaced, go to the REPAIR PROCEDURE .
  1. Connect Techstream unit and test drive the vehicle. Record ALL data duplicating the concern. Review the Knock Correct Learn Value and the Ignition (IGN) Advance.
  2. If the Knock Correct Learn Value drops from 17.0 CA to below 12.0 CA, and the IGN Advance goes to a negative (-) degree value while duplicating the concern, continue to step 3.

    If the values are comparable to a known good vehicle, the concern may NOT be related to this bulletin - diagnose per the Technical Information System (TIS) depending upon symptoms.

  3. Check the condition of the spark plugs and valve guides.
    • If 1 or more of the spark plugs has a brown residue on the porcelain and electrode, continue to the REPAIR PROCEDURE .
    • If the spark plugs appear normal, confirm that the valve stem oil clearance is within specification.

      Maximum Oil Clearance:

      Intake: 0.08 mm (0.0031 in.) 

      Exhaust: 0.1 mm (0.0039 in.) 

    If greater than specification, continue to the REPAIR PROCEDURE .

    If neither of these conditions are abnormal, the condition may NOT be related to this bulletin.

    Continue diagnosis using the applicable Repair Manual.

REPAIR PROCEDURE

NOTE:
  • For 2007 - 2012 MY 2WD LS 460 and 2WD LS 460L vehicles ONLY: Begin at step  1.
  • For 2009 - 2012 MY 4WD LS 460, 4WD LS 460L and LS 600h vehicles: Begin at step  4.

      • ECM part number [Refer to the PARTS INFORMATION section for the CURRENT PART NUMBER] 
      • Calibration ID(s) [Refer to the CALIBRATION IDENTIFICATION CHART for the NEW CALIBRATION ID] 
      • Dealer Code
      • Repair Date
      • Change Authority [This bulletin number] 
    2. Install the Authorized Modifications Label to the vehicle at the location shown in Figure 1. The Authorized Modifications Label is available through the MDC, P/N 00451-00001-LBL.
      NOTE: If the cylinder heads were previously replaced in L-SB-0033-08, do NOT replace them again.
