Introduction
Some customers of 2007 model year GS 350 and IS 350 vehicles may experience a M.I.L. “ON”
condition with DTC P0751 (Shift Solenoid “A” Performance – Shift Solenoid S1) stored (possibly
with DTCs P2714 or P0894). The Engine Control Module (ECM) (SAE term: Powertrain Control
Module/PCM) logic for DTC P0751 has been revised to prevent a false M.I.L. “ON”. Follow the repair
procedure in this bulletin to determine if recalibration of the ECM (PCM) is required.

M.I.L. "ON" DTC P0751
Repair Procedure
1. Using TIS Techstream, check for DTC(s) stored in the ECM (PCM).
2. Confirm that DTC P0751 (Shift Solenoid “A” Performance – Shift Solenoid S1) is stored as
a current DTC.
3. Check the Freeze Frame Data for each DTC stored to confirm which DTC(s) set first.
HINT
The DTC that is stored first will have 5 frames of Freeze Frame Data stored (see Figures
1 and 2).

Repair Procedure (Continued)
Figure 2. Example of Freeze Frame Data for P2714 with One Frame of Data
Does P0751 have 5 frames of Freeze Frame Data?
•YES — Go to step 4.
•NO — This TSIB does NOT apply. Refer to the Repair Manual and follow diagnosis for the
first stored or primary DTC (the DTC with 5 frames of Freeze Frame Data).
4. Clear all codes and test drive vehicle. Monitor vehicle during test drive and confirm if abnormal
shifting or a M.I.L. “ON” occurs.
Did abnormal shifting occur or did a M.I.L. light turn “ON” during the test drive?
•YES — This TSIB does NOT apply. Use Techstream to confirm DTCs and follow Repair
Manual diagnostic method for primary DTC, or refer to the Repair Manual for diagnostic
method based on shifting abnormality observed during the test drive.
•NO — Go to step 5.

Repair Procedure (Continued)
5. Refer to the Health Check information in Techstream and confirm if the CAL ID matches the
“Previous Calibration ID” or “New Calibration ID” listed in the Calibration Information chart in
this TSIB.
Does the calibration ID in the ECM (PCM) match the New Calibration ID listed in this TSIB?
•YES — The recalibration in this bulletin has been previously performed. Refer to the Repair
Manual for diagnosis.
•NO — This TSIB applies. Go to step 6 for the ECM (PCM) reprogramming process.
6. Check for the Authorized Modifications Label affixed to the vehicle in the location shown in
Figure 3 or 4. Confirm if the ECM (PCM) calibration has been updated. If the calibration ID listed
is NOT the latest ECM (PCM) calibration — go to step 7.
