SYSTEM – TROUBLESHOOTING\n\nDIAGNOSTIC TROUBLE CODE MATRIX CHART\nIf a malfunction code is displayed during the diagnostic trouble code check, check the circuit listed for that code\nin the table below (Proceed to the page given for that circuit.).\n\nDTC No. | Diagnosis | Page\n\n(Normal)*1 | • Source voltage drop | RS–52\n\n11 | • Short in squib circuit or front airbag sensor circuit (to ground)\n• Front airbag sensor or center airbag sensor assembly malfunction | RS–54\n\n12 | • Short in squib circuit (to B+)\n• Open in front airbag sensor circuits | RS–60\n\n13 | • Short in D squib circuit (between D+ wire harness and D– wire harness) | RS–66\n\n14 | • Open in D squib circuit | RS–73\n\n15 | • Open in front airbag sensor circuit | RS–78\n\n22*2 | • SRS warning light system malfunction | RS–82\n\n31 | • Center airbag sensor assembly malfunction | RS–86\n\n53 | • Short in P squib circuit | RS–87\n\n54 | • Open in P squib circuit | RS–92\n\nHINT:\n*1 When the SRS warning light remains lit up and the diagnostic trouble code is the normal code, this means\na source voltage drop.\n*2 Code 22 is recorded when a malfunction occurs in the SRS warning light system.\nIf an open malfunction occurs in the SRS warning light system, the SRS warning light does not light up, so\nthat until the malfunction is repaired, the diagnostic trouble codes (including code 22) cannot be confirmed.\n\nPROBLEM SYMPTOM CHART\nProceed with troubleshooting of each circuit in the table below.\n\nProblem Symptom | Inspection Item | Page\n\n• With the ignition switch at ACC or ON, the SRS warning light\nsometimes lights up after approx. 6 seconds have elapsed.\n• SRS warning light is always lit up even when ignition switch\nis in the LOCK position. | • SRS warning light system\n( Always lit up, when ignition\nswitch is in LOCK position. ) | RS–96\n\n• Diagnostic trouble code not displayed.\n• SRS warning light is always lit up with the DTC check procedure.\n• Diagnostic trouble code displayed without Tc and E1 terminal\ncorrection. | • Tc terminal circuit |
