Did the on-demand DTC change from B007F:1A to B007F:13?

Yes	GO to A11
No	GO to A5

A5 CHECK FOR A SHORT BETWEEN THE PASSENGER SAFETY BELT RETRACTOR PRETENSIONER CIRCUITS

Ignition OFF. Depower the SRS. REFER to: Supplemental Restraint System (SRS) Depowering (501-20B Supplemental Restraint System, General Procedures). Disconnect RCM C310A and C310B. Measure:
