SUPPLEMENTAL RESTRAINT SYSTEM – TROUBLESHOOTING
DIAGNOSTIC TROUBLE CODE MATRIX CHART
If a malfunction code is displayed during the diagnostic trouble code check, check the circuit listed for that code
in the table below (Proceed to the page given for that circuit.).
DTC No. | Diagnosis | Page
(Normal)*1 | • Source voltage drop | RS–52
11 | • Short in squib circuit or front airbag sensor circuit (to ground)
• Front airbag sensor or center airbag sensor assembly malfunction | RS–54
12 | • Short in squib circuit (to B+)
• Open in front airbag sensor circuits | RS–60
13 | • Short in D squib circuit (between D+ wire harness and D– wire harness) | RS–66
14 | • Open in D squib circuit | RS–73
15 | • Open in front airbag sensor circuit | RS–78
22*2 | • SRS warning light system malfunction | RS–82
31 | • Center airbag sensor assembly malfunction | RS–86
53 | • Short in P squib circuit | RS–87
54 | • Open in P squib circuit | RS–92
HINT:
*1 When the SRS warning light remains lit up and the diagnostic trouble code is the normal code, this means
a source voltage drop.
*2 Code 22 is recorded when a malfunction occurs in the SRS warning light system.
If an open malfunction occurs in the SRS warning light system, the SRS warning light does not light up, so
that until the malfunction is repaired, the diagnostic trouble codes (including code 22) cannot be confirmed.
PROBLEM SYMPTOM CHART
Proceed with troubleshooting of each circuit in the table below.
Problem Symptom | Inspection Item | Page
• With the ignition switch at ACC or ON, the SRS warning light
sometimes lights up after approx. 6 seconds have elapsed.
• SRS warning light is always lit up even when ignition switch
is in the LOCK position. | • SRS warning light system
( Always lit up, when ignition
switch is in LOCK position. ) | RS–96
• Diagnostic trouble code not displayed.
• SRS warning light is always lit up with the DTC check procedure.
• Diagnostic trouble code displayed without Tc and E1 terminal
correction. | • Tc terminal circuit | RS–98
