Technical Service Bulletin # 97-T-03
Date: 970201
Air Bag - Telltale ON with DTC 61 Set
BULLETIN NO.: 97-T-03
ISSUE DATE: February, 1997
GROUP/SEQ. NO.: SIR-01
CORPORATION NO.: 788204
SUBJECT:
AIR BAG Telltale On with DTC 61 in Sensing and Diagnostic Module (SDM) Memory (Verify the SDM Connector and CPA Device Are Properly
Installed)
MODELS AFFECTED:
1996 and 1997 Saturns
Condition
AIR BAG telltale is On with DTC 61 set in the sensing and diagnostic module (SDM) memory.
Cause
The SDM connector has a dual-action shorting bar across terminal cavities 6 & 7, which connects the AIR BAG telltale lamp to ground. One end of the
dual-action shorting bar is opened when the SDM connector is fully seated in the SDM. The other end of the shorting bar is opened when the CPA
device is fully seated in the SDM connector. The CPA device also locks the SDM connector body into the SDM module
If the ignition is turned to the ON position and either the CPA is not fully engaged or the SDM connector is not fully seated, the shorting bar will cause
the AIR BAG telltale to turn On and set a DTC 61.
Correction
When performing the "SIR Diagnostic System Check" in the "SIR Service Manual," one of the steps is to check that the SDM connector is properly
installed in the SDM and that the connector position assurance (CPA) device is properly installed in the SDM connector. Refer to the following page for
checking the SDM's connector position assurance device to make sure it is properly installed. Also, refer to this bulletin for added information on how to
remove the SDM connector from the SDM.
If the connector and CPA are installed correctly, refer to appropriate diagnostic chart in the appropriate year "SIR Service Manual."
Procedure
CAUTION:
WHEN YOU ARE PERFORMING SERVICE ON OR NEAR THE SIR COMPONENTS OR THE SIR WIRING, YOU MUST DISABLE THE
SIR SYSTEM. REFER TO THE DISABLE PROCEDURE IN THE SIR SERVICE MANUAL TO TEMPORARILY DISABLE THE SIR
SYSTEM. FAILURE TO FOLLOW THE CORRECT PROCEDURE COULD CAUSE AIR BAG DEPLOYMENT, PERSONAL INJURY, OR
UNNECESSARY SIR SYSTEM REPAIRS. THE INFLATABLE RESTRAINT SENSING AND DIAGNOSTIC MODULE MAINTAINS A
RESERVE ENERGY SUPPLY WHEN THE VEHICLE POWER IS INSUFFICIENT TO CAUSE DEPLOYMENT OF THE AIR BAGS, THE
RESERVE ENERGY SUPPLY PROVIDES THE DEPLOYMENT POWER. DEPLOYMENT POWER IS AVAILABLE FOR AS MUCH AS TEN
MINUTES AFTER DISCONNECTING THE VEHICLE POWER BY ANY OF THE FOLLOWING METHODS.
^
YOU TURN OFF THE IGNITION SWITCH.
^
YOU REMOVE THE FUSE THAT PROVIDES POWER TO THE INFLATABLE RESTRAINT SENSING AND DIAGNOSTIC MODULE.
^
YOU DISCONNECT THE VEHICLE BATTERY FROM THE VEHICLE ELECTRICAL SYSTEM.
When checking the SDM connector, make sure that the CPA device is completely inserted into the SDM connector. If the CPA device is not completely
inserted into the SDM connector, the shorting bar will not be opened, and the CPA device will not function as a lock for the SDM connector.
