DTC B0017 - Diagnostic Chart (Chart 2 Of 2):






CIRCUIT DESCRIPTION

Schematic:






When the ignition switch is turned On and during vehicle operation, the SDM performs tests to detect system faults. One test the SDM performs is to monitor the passenger inflator module high circuit and passenger inflator module low circuit voltage difference. By monitoring voltage difference, the SDM is able to calculate the passenger loop resistance. High resistance indicates an open somewhere in the passenger deployment loop.

DTC PARAMETERS:
DTC B0017 can be set when the passenger loop resistance is high. The following conditions must be met to set this DTC:
^ Ignition voltage is present at the SDM and continuous.
^ The passenger deployment loop resistance is over 3.705 Ohms or circuit 1403 under 2 Volts and deployment loop resistance over 6 Ohms.
^ Fault is present for half a second.

ACTION TAKEN:
^ DTC B0017 will set.
^ The air bag telltale will be On.

DIAGNOSTIC AIDS:
^ When attempting to diagnose an intermittent passenger loop fault, use the Scan tool to monitor current DTC's Wiggle wires and check connections while watching for a current DTC to appear and/or disappear on Scan tool.
^ Always start diagnosis of SIR DTCs with an inspection of wiring and components for visible damage.
^ An open in circuits 1403 or 1404 to the passenger inflator module could cause this DTC.
^ Always perform the "SIR Diagnostic System Check" before using this chart. Diagnostic System Check
