Some 2010 - 2012 model year IS 250 and IS 250C vehicles equipped with automatic transmissions may exhibit a MIL "ON" condition with Diagnostic Trouble Codes (DTCs) P014C, P014D, P014E, or P014F present. The Engine Control Module/ECM (SAE term: Powertrain Control Module/PCM) logic has been modified to reduce the possibility of this condition occurring. Use the following procedure to reprogram the ECM (PCM).

Repair Procedure

1. Using Techstream confirm one of the following DTCs is present:

^ P014C: A/F Sensor Slow Response - Rich to Lean Bank 1 Sensor 1

^ P014D: A/F Sensor Slow Response - Lean to Rich Bank 1 Sensor 1

^ PO14E: A/F Sensor Slow Response - Rich to Lean Bank 2 Sensor 1

^ PO14F: A/F Sensor Slow Response - Lean to Rich Bank 2 Sensor 1

If other DTCs are present this bulletin does NOT apply. Continue diagnosis per Repair Manual procedures.





2. Check for the Authorized Modifications Label affixed to the vehicle in the location shown in Figure 1. Confirm if the ECM (PCM) calibration has been updated. If the calibration ID listed is NOT the latest ECM (PCM) calibration - go to step 3.

3. Flash reprogram the ECM (PCM).

NOTE

^ The GR8 Battery Diagnostic Station MUST be used in Power Supply Mode to maintain battery voltage at 13.5 volts while flash reprogramming the vehicle.

^ For details on how to use the GR8 Battery Diagnostic Station, refer to the GR8 Instruction Manual located on the Technical Information System (TIS), Diagnostics - Tools & Equipment - Battery Diagnostics.

Follow the procedures outlined in Service Bulletin No. L-SB-0015-10, "Techstream ECU Flash Reprogramming Procedure� and flash reprogram the ECM (PCM) with the NEW calibration file update.

4. Install the Authorized Modifications Label.

A. Using a permanent marker enter the following information on the label:

^ 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]

B. Affix 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.

5. Test drive the vehicle to confirm proper vehicle operation.
