INFO. ON DIAGNOSTIC TROUBLE CODE (DTC) 55 SET. Cadillac Catera 1997

SUBJECT: INFORMATION ON DIAGNOSTIC TROUBLE CODE (DTC) 55 SET (AIR BAG WARNING LAMP ON)

MODELS: 1997 CADILLAC CATERA

SOME 1997 CATERAS MAY EXHIBIT A CONDITION WHERE THE AIR BAG WARNING LAMP COMES ON WITH A DIAGNOSTIC TROUBLE CODE (DTC) 55 STORED IN "HISTORY". LOW BATTERY VOLTAGE MAY BE THE CAUSE OF THIS DTC SETTING. THIS IS MOST LIKELY TO OCCUR DURING THE SHIPPING PROCESS, BUT COULD ALSO OCCUR DURING LONG PERIODS OF STORAGE, OR IF A WIRING FAULT OCCURS THAT DISCHARGES THE BATTERY.

IN THE EVENT OF THE OCCURRENCE OF A "HISTORY" DTC 55 SETTING, THE AIR BAG SENSING AND DIAGNOSTIC MODULE (SDM) SHOULD NOT BE REPLACED. INSTEAD, THE HISTORY DTC 55 SHOULD BE CLEARED USING THE TECH 2 AND THE CAUSE OF THE LOW BATTERY VOLTAGE DIAGNOSED AND REPAIRED.

FOR A "CURRENT" AIR BAG DTC 55 SETTING, FOLLOW THE APPROPRIATE DIAGNOSIS CHART IN THE SERVICE MANUAL.
