PINPOINT TEST 7 DTC B2293 - RESTRAINT SYSTEM - AIR BAG FAULT
STEP INSPECTION ACTION
1 CHECK FOR A HARD OR INTERMITTENT DTC
WARNING:
  • Restraint system diagnostic tools are for service only. Tools must be removed prior to operating the vehicle over the road. Failure to remove restraint system diagnostic tools could result in injury and possible violation of vehicle safety standards.
WARNING:
  • Never probe the connectors on the air bag module. Doing so can result in air bag deployment, which can result in personal injury.
WARNING:
  • The safety belt pretensioner is a pyrotechnic device. Always wear safety glasses when repairing an air bag equipped vehicle and when handling a safety belt buckle pretensioner or safety belt retractor pretensioner. Never probe a pretensioner electrical connector. Doing so could result in pretensioner or air bag deployment and could result in personal injury.
WARNING:
  • Never probe the electrical connector on a safety canopy module. Doing so can result in safety canopy deployment.
NOTE:
  • The SRS must be fully operational and free of faults before releasing the vehicle to the customer.

  • Enter the following diagnostic mode on the IDS or equivalent tester: View and Record DTC B2293 Fault PIDs
  • Was on-demand DTC B2293 retrieved? 
 Yes This is a hard fault. The fault condition is now present. This fault cannot be cleared until it is corrected and the DTC is no longer retrieved during the on-demand self-test.
CHECK for causes of the intermittent fault at or near the affected air bag module connector. REPAIR any intermittent concerns found. If an intermittent concern was found and repaired, Go to next step.
If an intermittent concern was not found and repaired, USE the fault PIDs recorded and GO to the appropriate pinpoint test step.
For driver air bag module squib 1 with a short to ground fault, Go to step 3.
For driver air bag module squib 1 with a short to battery fault, Go to step 5.
For driver air bag module squib 1 with an open circuit fault, Go to step 7.
For driver air bag module squib 1 with a low resistance fault, Go to step 11.
For passenger air bag module squib 1 with a short to ground fault, Go to step 14.
For passenger air bag module squib 1 with a short to battery fault, Go to step 15.
For passenger air bag module squib 1 with an open circuit fault, Go to step 16.
For passenger air bag module squib 1 with a low resistance fault, Go to step 18.
For driver air bag module squib 2 with a short to ground fault, Go to step 20.
For driver air bag module squib 2 with a short to battery fault, Go to step 22.
For driver air bag module squib 2 with an open circuit fault, Go to step 24.
For driver air bag module squib 2 with a low resistance fault, Go to step 28.
For passenger air bag module squib 2 with a short to ground fault, Go to step 31.
For passenger air bag module squib 2 with a short to battery fault, Go to step 32.
For passenger air bag module squib 2 with an open circuit fault, Go to step 33.
For passenger air bag module squib 2 with a low resistance fault, Go to step 35.
No CHECK for causes of the intermittent fault. ATTEMPT to recreate the hard fault by flexing the wire harness and cycling the ignition key frequently. REPAIR any intermittent concerns found. Go to next step.
39 CHECK FOR ADDITIONAL DTCs
  • Refer to the continuous memory DTCs recorded during Step 1.
  • Were any continuous memory DTCs retrieved during Step 1 ? 
 Yes Do not clear any DTCs until all DTCs have been resolved. See DIAGNOSTIC TROUBLE CODE (DTC) INDEX - RESTRAINTS CONTROL MODULE (RCM) , for pinpoint test direction.
No RECONNECT the system. If previously directed to deactivate the system, REACTIVATE the system. See SUPPLEMENTAL RESTRAINT SYSTEM (SRS) DEACTIVATION AND REACTIVATION , . REPOWER the system. See DEPOWERING AND REPOWERING , . PROVE OUT the system. CLEAR all RCM and OCS module DTCs.
