air bag code

[Scottydoggs]

ok, so i got my car scanned for the air bag, and its a b1026 code, it is driver side deployment loop is open. my friend tried to reset it and came right back.

also my steering wheel radio controls dont work, so im leaning towards the clock spring.

but from what i got from google was it could be the seat belt, clock spring, or the air bag its self, or wire connections.

all data was down when he tried to get more info on the code, hes going to get back to me tomorrow with what ever he finds.

any one out there know anything about this code and where it may lead me?

best part is all it cost was a 1/2 joint they usually charge 70 bucks just to hand you the code.

i also took him for a ride and he thinks its the tcc acting up in my trans, hes going to call the trans shop he deals with to see what they would charge to change it for his cousin wink wink :th_lipssealed2:

Here is part of the diag sheet for that code

Circuit Description
When you first turn the ignition switch to the RUN position, the Inflatable Restraint Sensing and Diagnostic Module (SDM) performs tests to diagnose critical malfunctions within the SDM. Next the SDM measures IGNITION 1 voltage to ensure that the IGNITION 1 is within respective normal voltage range. Then the SDM proceeds with the DEPLOYMENT LOOP CONTINUITY test. During the DEPLOYMENT LOOP CONTINUITY test, the SDM measures the voltage difference between DRIVER SIDE HIGH and DRIVER SIDE LOW.

Conditions for Setting the DTC

The voltage difference between DRIVER SIDE HIGH terminal 2 and DRIVER SIDE LOW terminal 3 is more than or equal to 400 millivolts.
The malfunction must be present for at least 500 milliseconds during one of the following tests:
DEPLOYMENT LOOP CONTINUITY If the malfunction is detected in this test, the RESISTANCE MEASUREMENT test will not be performed.
CONTINUOUS MONITORING
Action Taken When the DTC Sets


The SDM sets a diagnostic trouble code.
The SDM turns ON the AIR BAG warning lamp.
Conditions for Clearing the DTC


Current DTC The voltage difference between DRIVER SIDE HIGH terminal 2 and DRIVER SIDE LOW terminal 3 is less than 400 millivolts for 500 milliseconds.
History DTC
You issue a scan tool CLEAR CODES command.
After 250 malfunction free ignition cycles have occurred
Diagnostic Aids
The following may cause an intermittent condition:


A poor connection at the Inflatable Restraint Steering Wheel Module column connector terminals A and B
A poor connection at the upper Inflatable Restraint steering wheel coil connector terminals A and B
A poor connection at the SDM terminals 2 and 3
An open in circuit 347
An open in circuit 348
An intermittent open in the Inflatable Restraint Steering Wheel Module Coil could also set this DTC. To test for a bad Inflatable Restraint Steering Wheel Module Coil, clear the DTCs, then turn the steering wheel back and forth with the ignition switch in the RUN position. If the AIR BAG warning lamp comes ON and DTC B1026 has set again, the cause is likely the Inflatable Restraint Steering Wheel Module Coil is malfunctioning.
When measurements are requested in this table, use the J 39200 DMM with the correct terminal adapter from the J 35616-A Connector Test Adapter Kit. When an inspection for proper connection is requested, refer to Testing for Electrical Intermittents. When a wire, connector or terminal repair is requested, use the J 38125-B Terminal Repair kit and refer to Wiring Repairs.

good stuff there thanks.
