Supercede:

This bulletin is being revised to add VIN breakpoints. Please discard Corporate Bulletin Number 11-09-41-002B (Section 09 - Restraints).

Condition

In extremely rare cases, some customers may comment that the air bag warning lamp is illuminated. This condition may be intermittent and when

checking the vehicle for DTCs, the SDM may report B0083, B0084, B0085, B0086, B0087 and/or B0088 with symptom code 0F. The code will be

stored in history and may be repeated. The code probably will not be current.

Cause

This condition may be caused by possible electro-magnetic interference (EMI) in the Amarillo, Texas area from external sources such as aviation

airspace traffic radar, creating erratic sensor information to the SDM.

Correction

An updated software calibration has been released to address this condition.

BEFORE beginning the programming/reprogramming event, please refer to the Programming/Reprogramming Checklist section in this bulletin.

1. Verify the battery voltage is more than 12 volts but less than 16 volts before proceeding with reprogramming. The battery must be fully

charged BEFORE reprogramming a control module.

2. During reprogramming, the battery voltage must be maintained within the proper range of 12-15.5 volts. CONNECT the approved

Midtronics(R) PSC 550 Battery Maintainer (SPS Programming Support Tool (EL-49642) to the vehicle or the GR8 (EL50313) in the power

supply mode.

瀚慖f the above recommended tools are not available, DO NOT connect a battery charger to the vehicle. CONNECT a fully charged 12V

jumper or booster pack that is disconnected from the AC voltage supply.

Notice

It is essential that the TIS terminal, MDI, Tech 2(R) and/or Scan Tool are updated with the latest software available.

3. Verify that the devices being used are updated with the latest available software version BEFORE beginning the reprogramming event.

4. BEFORE beginning reprogramming you MUST refer to Control Module References in SI for the appropriate Programming and Setup

procedures.

5. If a wireless connection will be used for reprogramming, a secure service department connection MUST be used. DO NOT use any public

WiFi connection from the customer lounge.

6. Reprogram the SDM using the Service Programming System (SPS) with the latest calibrations available on TIS2WEB. Refer to the SPS

procedures in SI.

Programming/Reprogramming Checklist

2010 Cadillac Truck Escalade EXT AWD V8-6.2L Page 101

- Turn OFF or disable any electrical system, accessory or component that may put an additional electrical load on the vehicle battery during

reprogramming.

- Only program a module when you have been instructed to by Service Information (SI), a Bulletin, TAC or a Techline operator.

- You MUST refer to Control Module References in SI for the appropriate Programming and Setup procedures.

- Thoroughly review the Service Programming System (SPS) in SI BEFORE reprogramming any module.

- Some modules will require specific additional programming setup events to be performed BEFORE reprogramming. Refer to Control

Module References for the appropriate Programming and Setup procedures in SI.

- Capture and record the Engine Oil Life Remaining information. Record the Engine Oil Life Remaining as a percentage (%).

- Follow all on-screen instructions in SPS. Verify that the ignition switch is in the proper position.

- If a wireless connection will be used for reprogramming, a secure service department connection MUST be used. DO NOT use any public

WiFi connection from the customer lounge.

- DO NOT run other programs on the computer while reprogramming.

- Use the approved Midtronics(R) PSC 550 Battery Maintainer (SPS Programming Support Tool EL-49642) or the GR8 (EL50313) in the

power supply mode.

- DO NOT disturb the vehicle, programming device(s) or operate any of its features during reprogramming.

- Some modules will require specific additional programming setup events to be performed AFTER reprogramming. Refer to Control

Module References for the appropriate Programming and Setup procedures in SI.

- Use a Scan Tool to reset the Engine Oil Life Remaining information to the previous percentage (%) that was recorded before starting the

reprogramming event.

- Verify that all DTCs are cleared after performing the reprogramming event.

- In the event of an interrupted or unsuccessful reprogramming event, document the SPS Error. DO NOT cycle the ignition. DO NOT replace

the SDM. Refer to the latest version of PI0592 - Service Programming System (SPS) Errors in SI.

- If further assistance is required call Techline.
