The airbag connectors in behind the front kick panels have high resistance. The fix is to replace them. Here is TSB's

#05-09-41-001B: Supplemental Inflatable Restraint (SIR) Light ON, Diagnostic Trouble Codes (Inspect/Replace IP Harness to Inflatable Restraint Module (Air Bag) Yellow 4-Way Connector C221 and/or C222) - (Jun 2, 2008)

Subject:
Supplemental Inflatable Restraint (SIR) Light ON, Diagnostic Trouble Codes (DTC) B0013, B0014, B0017, B0018, B0024, B0026, B0043, B0044 (Inspect and/or Replace IP Harness to Inflatable Restraint Module (Air Bag) Yellow 4-Way Connector C221 and/or C222)

Models:
2003-2006 Cadillac Escalade Models

This bulletin is being revised to add the 2007 model year for pickups and change a part number. Please discard Corporate Bulletin Number 05-09-41-001A (Section 09 -- Restraints).

Condition
Some customers may comment that the Service Supplemental Inflatable Restraint Light is on.

Diagnosis with a scan tool may indicate a DTC B0013, B0014, B0017, B0018, B0024, B0026, B0043, B0044.

Cause
The most likely cause of any one of the following DTCs: B0013, B0014, B0017, B0018, B0024, B0026, B0043, B0044 is improper connection/high resistance in the IP harness to inflatable restraint module connector C221 and/or C222.

Diagnostic Information
DTC B0013, B0014, B0017, B0018, B0024, B0026, B0043, B0044 will set when one of the following conditions occur:
• The SDM detects the air bag module deployment loop resistance is greater than 4.8 ohms for 500 milliseconds.
• The SDM detects that the voltage at the air bag module high control is less than 2.4 volts and deployment loop resistance is 6 ohms or greater for 500 milliseconds.
• For additional diagnostic information, refer to DTC B0013, B0014, B0017, B0018, B0024, B0026, B0043, B0044 in the appropriate SI Document.

Correction

DO THIS
Test for proper connection/high resistance at connector C221 and/or C222.

Don't Do This
DO NOT replace SIR system components prior to testing for proper connection/high resistance in C221 and/or for DTCs B0013, B0014, B0017, B0018, B0024, B0026, B0043, B0044.

Caution: When performing service on or near the SIR components or the SIR wiring, the SIR system must be disabled. Refer to SIR Disabling and Enabling Zones. Failure to observe the correct procedure could cause deployment of the SIR components, personal injury, or unnecessary SIR system repairs.

Important: The IP harness to inflatable restraint module connectors C221 or C222 is NOT located at the base of the steering column...
• C221 (4 Cavities) -- I/P Harness to Body Harness, behind the left kick panel
• C222 (4 Cavities) (w/o HP2) -- I/P harness to body harness, behind the right kick panel
• C222 (4 Cavities) (w/HP2) -- Behind the left side I/P access panel
• Refer to the Master Electrical Component List for additional location information.

1. Remove the appropriate side door sill plate.
2. Remove the appropriate side hinge pillar panel.
3. Locate the IP harness to inflatable restraint module yellow 4-way connector C221 or C222.
4. Inspect the IP harness to inflatable restraint module connector C221 or C222 for proper connection.
5. Disconnect and reconnect the IP harness to inflatable restraint module connector C221 or C222 THREE times.
6. Clear the DTC and road test the vehicle.
• If DTCs B0013, B0014, B0017, B0018, B0024, B0026, B0043, B0044 DOES NOT reset, no additional repairs are necessary. Continue with step 10.
• If DTCs B0013, B0014, B0017, B0018, B0024, B0026, B0043, B0044 DOES reset, the most likely cause is high resistance in the IP harness to inflatable restraint module connector C221 or C222. Continue with the next step.
7. Replace the appropriate connector C221 and/or C222, P/N's 15306186 and 88987998. Refer to SIR/SRS Wiring Repairs (SI Document ID #325229).
8. Road test the vehicle and confirm that the repair is complete.
9. Install the driver's side hinge pillar panel.
10. Install the driver's side door sill plate.

2009 chevy impala left front side deployment loop resistance B0014 above threshold
the following link covers yours reqest The driver frontal loops 1 and 2 are the loops to the steering wheel air bag. The SDM(sensing and diagnostic module for the air bag) is seeing these circuits as open. There is a bullitin for problems with a loose connection for the yellow connector behind the left kick panel(right behind the e brake and hood release). I would remove the kick panel, and disconnect and reconnect the connector a couple times. See if the light goes out. Or wiggle and move the connector with the key on, as the light should go out if it makes good connection. If it does go out you need to replace this connector. Good luck.

Problem with my cruise control and ABS light on 03 Explorer
Anti-Lock Control —Vehicles Built After 03/2002 The 3-channel anti-lock brake system consists of the following components:
  • front wheel speed sensors
  • front wheel speed sensor rings
  • hydraulic control unit (HCU)
  • Anti-lock brake control module (ECU)
  • rear wheel speed sensor
  • rear wheel speed sensor rings
  • yellow anti-lock brake warning indicator
The 4-channel anti-lock brake system with traction control and stability assist system consists of the following components:
  • active brake booster with integral solenoid
  • brake booster release switch
  • front wheel speed sensors
  • front wheel speed sensor rings
  • hydraulic control unit (HCU)
  • stability assist module (ECU)
  • stability assist event indicator
  • lateral accelerometer
  • longitudinal accelerometer (4x4)
  • rear wheel speed sensors
  • rear wheel speed sensor rings
  • steering wheel position sensor
  • yaw rate sensor
  • yellow anti-lock brake warning indicator
  • brake pressure transducer
  • traction control switch
---------------------------------------------------------------------
I suspect the abs issue is causing the speed control not to work if it happened at the same time the cruise control stopped working. When the yellow ABS light comes on, it means the ABS is dactivated. You may have a faulty accelerometer which senses acceleration and yaw (side to side lean). I have not seen a bad one but you said it is sensitive to acceleration.
I would unplug it and see what happens. The connector should have a small tab to depress so you can pull the connector out.
Here is where it is:

Accelerometer Removal and Installation
  1. NOTE: The accelerometer is located under the center, rear passenger seat carpet. (I think you have to remove seat for access).
    Cut the carpeting along the perforations.
  1. Disconnect the electrical connector.
  1. Remove the nuts and remove the accelerometer.
cd31596.gif
Have dealer hook up tester and pull fault codes if you can't find an easy solution.
Some background info
  • A malfunction in the anti-lock brake system will cause the anti-lock brake control module to shut off or inhibit the system. However, normal power-assisted braking remains.
  • Malfunctions are indicated by the yellow ABS warning indicator in the instrument cluster.
  • The anti-lock brake system is self-monitoring. When the ignition switch is turned to the RUN position, the anti-lock brake control module will carry out a preliminary self-check on the anti-lock electrical system indicated by a three-second illumination of the yellow ABS warning indicator in the instrument cluster.
  • During vehicle operation, including normal and anti-lock braking, the anti-lock brake control module monitors all electrical anti-lock functions and some hydraulic operations.
  • Each time the vehicle is driven, as soon as vehicle speed reaches approximately 20 km/h (12mph), the anti-lock brake control module turns on the pump motor for approximately one-half second. At this time, a mechanical noise may be heard. This is a normal function of the self-check by the anti-lock brake control module.
  • Pedal pulsation coupled with noise while braking on loose gravel, bumps, wet or snowy roads is normal and indicates correct functioning of the anti-lock brake system.
    • Warning Lamp Indicator
    The anti-lock brake system (ABS) uses the yellow ABS warning indicator to alert the driver of a malfunctions in the ABS.
    The yellow ABS warning indicator will come on to warn the driver that the ABS has been turned off due to a symptom that exists in the ABS. Normal power assist braking remains but wheels can lock during a panic stop while the yellow ABS warning indicator is illuminated.

    -----------------------------------------
    Please report back, I am curious if that is what it is. Good luck
