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).

Figure 1. Example of Freeze Frame Data for P0751 with 5 Frames of Data (Titled -3, -2, -1, 0, and 1)

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.

7. 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 – Battery.

Follow the procedures outlined in TSIB No. SS002-07, “Techstream ECU Flash Reprogramming

Procedure”, and ﬂash the ECM (PCM) with the NEW calibration ﬁle update.
