It could be a disconnected wire, a corroded ground wire, etc. It is difficult to say. I would suggest you stop by your local dealer for a quick test.

</td></tr></tbody></table>Circuit/System Description

The inflatable restraint front end sensor utilizes a unidirectional 2-wire circuit. The front end sensor modulates current on the interface to send ID, State of Health, and deployment commands to the inflatable restraint sensing and diagnostic module (SDM). The SDM serves as a power source and a ground for the front end sensor. When the ignition is turned ON and input power from the SDM is first detected, the SIS responds by performing internal diagnostics and sending an ID to the SDM. The SDM considers the ID to be valid if the response time is less than 5 seconds. The front end sensor continually communicates status messages to the SDM, which determines if a fault is present in the front end sensor circuit. When a fault is detected, the SDM resets the front end sensor twice by removing and reapplying power to it. If the fault is still present, the SDM will set a DTC.
Conditions for Running the DTC

Ignition voltage is between 9-16 volts.
Conditions for Setting the DTC

All of the following conditions exist for 2.5 seconds:
B0100 for Front End Sensor 1 or B0103 for Front End Sensor 2

<table border="0"><tbody><tr><td valign="top">• </td><td valign="top">A valid ID message is not received within 5 seconds of the front end sensor being powered up. </td></tr></tbody></table>
<table border="0"><tbody><tr><td valign="top">• </td><td valign="top">The SDM has not received a message from the front end sensor for more than 375 milliseconds.</td></tr></tbody></table>
<table border="0"><tbody><tr><td valign="top">• </td><td valign="top">The SDM has reset the front end sensor twice without detecting a valid ID message.</td></tr></tbody></table>

B0101 for Front End Sensor 1 or B0104 for Front End Sensor 2

<table border="0"><tbody><tr><td valign="top">• </td><td valign="top">The SDM has received an ID message from the front end sensor, which does not match the ID stored in the SDM memory. </td></tr></tbody></table>
<table border="0"><tbody><tr><td valign="top">• </td><td valign="top">The SDM has reset the front end sensor twice without detecting a correct ID message.</td></tr></tbody></table>

B0102 for Front End Sensor 1 or B0105 for Front End Sensor 2

The SDM has received a NOK message from the front end sensor.
Action Taken When the DTC Sets

<table border="0"><tbody><tr><td valign="top">• </td><td valign="top">The SDM commands the AIR BAG indicator ON via serial data communications. </td></tr></tbody></table>
<table border="0"><tbody><tr><td valign="top">• </td><td valign="top">The SIR System is disabled and no deployments are allowed.</td></tr></tbody></table>

Conditions for Clearing the DTC

<table border="0"><tbody><tr><td valign="top">• </td><td valign="top">The condition responsible for setting the DTC no longer exists and the scan tool Clear DTCs function is used. </td></tr></tbody></table>
<table border="0"><tbody><tr><td valign="top">• </td><td valign="top">A history DTC will clear once 255 malfunction-free ignition cycles have occurred.</td></tr></tbody></table>

Circuit/System Testing

Important: When removing connectors inspect for damage or corrosion. Damage or corrosion in the following requires repair or replacement of the affected component/connector.
<table border="0"><tbody><tr><td valign="top">• </td><td valign="top">The front end sensor</td></tr></tbody></table>

<table border="0"><tbody><tr><td valign="top">• </td><td valign="top">The SDM module</td></tr></tbody></table>
<table border="0"><tbody><tr><td valign="top">• </td><td valign="top">The front end sensor wiring harness connector</td></tr></tbody></table>
<table border="0"><tbody><tr><td valign="top">• </td><td valign="top">The SDM wiring harness connector</td></tr></tbody></table>
Ignition ON, use the scan tool as clear SIR codes then recheck for DTCs. Verify that DTC B0101, B0102, B0104, or B0105 is not set.
<table border="0"><tbody><tr><td valign="top">⇒</td><td valign="top">If DTC B0101 or B0102 is set current replace the front end sensor 1/left.</td></tr></tbody></table>

<table border="0"><tbody><tr><td valign="top">⇒</td><td valign="top">If DTC B0104 or B0105 is set current replace the front end sensor 2/right.</td></tr></tbody></table>
If DTC B0100 is current, disconnect the front end sensor 1 connector, or if DTC B0103 is current disconnect the front end sensor 2 connector. Refer to front end sensor replacement in Repair Instructions for location of connector.
Remove the SDM connector, refer to SDM replacement in Repair Instructions for connector location.
Test the signal and voltage circuits between the SDM and front end sensor. Verify that a short to voltage, short to ground, or open/low resistance does not exist.
<table border="0"><tbody><tr><td valign="top">⇒</td><td valign="top">If any of the above conditions are found make the appropriate repair.</td></tr></tbody></table>
Reconnect all SIR components. Ignition ON, use the scan tool to clear the DTCs then recheck for DTCs. Verify no DTCs are set.
<table border="0"><tbody><tr><td valign="top">⇒</td><td valign="top">If DTC B0100 was current replace the front end sensor 1. After replacement refer to Repair Verification. </td></tr></tbody></table>

<table border="0"><tbody><tr><td valign="top">⇒</td><td valign="top">If DTC B0103 was current replace the front end sensor 2. After replacement refer to Repair Verification. </td></tr></tbody></table>

Repair Verification

Ignition ON, use the scan tool to clear the DTCs then recheck for DTCs. Verify no DTCs are set.

<table border="0"><tbody><tr><td valign="top">⇒</td><td valign="top">If DTC B0100 or B0103 was current replace the SDM.</td></tr></tbody></table>

Where would one buy the sensor? Are both right and left sensors the same? If it takes 255 cycles of the ignition key to reset the system I guess I'll have to take it back to my repair guy and see it the code will clear since I just cleaned the connectors on both sensors.

I got the B0100 code and cleaned them...should I just bite the bullet and replace the left sensor?

I went to Ebay and found a used one for $45. I put it in and my light never came on. I have a shop that I use who rechecked for active codes - there were none - and then cleared the history. It was a 10 minute fix.

The store on Ebay I bought from is: "Below wholesale automotive parts" and is administered by dpart1122

They have a 14 day return policy. Just be sure you have the upgraded part # and don't settle for one that "looks exactly like the one I have". The sensor is specific to a vehicle! I have a GMC Sierra 1500 and it uses part # 10370149

Both front sensors are the same #

Hope this helps!

Also, they said I need a whole new radio assembly, cost $380.00.

Like one of the other posters stated the air bag sensors on the front of the truck are simple to replace. Don't pay the shop to do it. Just make sure to disconnect the battery before changing them out to avoid the chance of current making it through the system.

I had the same problem with the cd / radio players in my old Z71 and my current truck. I pulled it out and sent it to a shop I found on EBAY. They advertise the repair in the bidding section. It cost me somewhere around $180.00. The turn around time (including shipping both ways) was about 1 week. They even sent me my old CD's back that were stuck in the CD changer.

Here is the link to their page:

Toyota, GMC Chevy Buick Olds Pontiac items in Original Car Audio 952-707-6200 store on eBay!

Hope this helps!

If not, it's the other one. I then went to the independent garage that did the code check and had them clear the code again - total cost to them, $20.
The radio...don't buy into them saying your radio is shot. Take it to a few other places and have them give you an idea of what to do. I have never heard of "new software" for my radio, nor do I know how I would download it into my radio...anyone else have a clue?

I've never heard of new "software" for a radio.

The company that repaired mine never mentioned anything other than having to replace mechanical parts / and or a circuit board inside of the radio.
