2006 AZERA PCM REPROGRAMMING PROCEDURE FOR COLD WOT 1-2 SHIFT HESITATION
This bulletin supersedes TSB # 06-40-007 to change the Nature/Cause codes.
DESCRIPTION:
Some 2006 Azera vehicles may exhibit a 1-2 shift hesitation under wide open throttle (WOT) operation when cold. WOT is when accelerator pedal is pushed to the floor.
To improve the above condition, this bulletin provides the procedure to reprogram the Powertrain Control Module (PCM) using the Hi-Scan Pro.
VEHICLES AFFECTED:
^ Model: 2006 AZERA vehicles
^ Affected vehicle production date range: Start of Production to February 13, 2006

IMPORTANT PREPARATION BEFORE STARTING REPROGRAMMING:
1. Turn off all lights (do not leave headlight switch in auto mode) and all accessories (including heater/AC/blower, radio, heated seats, rear defroster, etc.) to make certain the battery will not be discharged during reprogramming.
2. If the vehicle was in storage, you must START and RUN the engine for at least 10 minutes before reprogramming to assure there will be adequate stabilized vehicle battery voltage required for a successful reprogram. Battery voltage must remain above 11.0V for the duration of 20-25 minutes of reprogram.
CAUTIONS DURING REPROGRAMMING:
1. Perform reprogramming with the ignition key in the ON position.
2. Be careful not to disconnect any cables connected to the vehicle or Hi-Scan Pro during reprogramming.
3. Do not start the engine during reprogramming.
4. Do not turn the ignition key OFF during reprogramming.
5. When reprogramming is completed, turn the ignition key OFF then wait for 20 seconds. Start the engine to confirm proper operation of the vehicle.
PCM REPROGRAMMING PROCEDURE:
NOTE:
Verify that the vehicle is one of the affected vehicles by identifying the vehicle's production date, VIN and PCM ROM ID.
HI-SCAN PRO INSTALLATION PROCEDURE
1. Attach the Data Link Cable (DLC) 16-pin connector to the Hi-Scan Pro main body and securely tighten the two bolts.
2. Remove the current system software card from the Hi-Scan Pro and insert the reprogramming software card with the new PCM program into the Hi-Scan Pro top slot.
3. Plug the DLC connector from the Hi-Scan Pro into the vehicle's connector under the instrument panel on the driver's side.
AUTOMATIC REPROGRAMMING PROCEDURE
1. Turn the ignition key to the ON position. (Do not start the engine).
2. Turn the Hi-Scan Pro ON.
3. Select option "75. TG 3.8 1->2 SHIFT HESITATION IMPROVE" and press ENTER.
NOTE:
If option # 75 is not available on your card, you will need to update your software on the black 32MB reprogram card at hmaservice.com.
4. Select option "01. TG 3.8 1->2 SHIFT HESITATION [AUTO]" and press ENTER.
5. Enter "1229" as the password for automatic reprogramming mode and press ENTER.
6. The Hi-Scan Pro will establish communication, check the PCM ID, and reprogram the PCM.
NOTES:
^ The Hi-Scan Pro detects the current PCM ID, assigns the new PCM ID and displays them on the Hi-Scan Pro screen.
^ Check the PCM ID displayed on the Hi-Scan Pro screen to verify that the correct PCM software is being downloaded. Refer to the "ROM ID INFORMATION TABLE" shown in this bulletin.
^ If the Hi-Scan Pro does not download the program, use the "MANUAL REPROGRAMMING PROCEDURE".
7. When "REPROGRAMMING COMPLETED" message is displayed, turn the ignition key OFF for 20 seconds and then start the engine to confirm proper operation of the vehicle.
8. Check for any engine or transmission section diagnostic trouble codes (DTCs) using the Hi-Scan Pro and erase any DTCs present.
MANUAL REPROGRAMMING PROCEDURE:
CAUTION:
^ Manual Reprogramming must be performed only when Automatic Reprogramming fails.
^ If Automatic Reprogramming fails, turn the ignition switch OFF for about 10 seconds, place it back in the ON position and then perform Manual Reprogramming.
1. Turn the ignition switch to the OFF position for about 10 seconds and then back to the ON position. Turn the Hi-Scan Pro ON and press ENTER.
2. Select option "75. TG 3.8 1->2 SHIFT HESITATION IMPROVE" and press ENTER.
3. Select option "02. TG 3.8 1->2 SHIFT HESITATION [ERROR]" and press ENTER.
4. Select option "01. TG 3.8 AT: 39110-3C210" and press ENTER.
5. Enter "3210" as the password for Manual Reprogramming Mode and press ENTER. The Hi-Scan Pro will establish communication, check the PCM ID and reprogram the PCM.
NOTES:
^ The Hi-Scan Pro detects the current PCM ID, assigns the new PCM ID and displays them on the Hi-Scan Pro screen.
^ Check the PCM ID displayed on the Hi-Scan Pro screen to verify that the correct PCM software is being downloaded. Refer to the "ROM ID INFORMATION TABLE" shown in this bulletin.
6. When "REPROGRAMMING COMPLETED" message is displayed, turn the ignition key OFF for 20 seconds and then start the engine to confirm proper operation of the vehicle.
7. Check for any engine or transmission section diagnostic trouble codes (DTCs) using the Hi-Scan Pro and erase any trouble codes present.
