2007/2008/2009 Mazda CX9 Factory Service Repair Manual

2008 RESTRAINTS On-Board Diagnostic (Restraints) - Mazda CX-9 FOREWORD OUTLINE  The OBD (on-board diagnostic) system has the following functions:  Malfunction detection function: Detects malfunctions in the air bag system and outputs DTCs.  Data monitor function: Reads out specific input/output signals and the system status.  Diagnostic DTCs can be read/cleared using the M-MDS. FLOWCHART  Use the following flowchart to verify the cause of the trouble. NOTE:  While performing the inspection of the past malfunction code, the applicable DTCs may be added to memory by removing or disconnecting the related parts. Inspect only the DTCs that were indicated before inspecting.  When DTCs of the present malfunction are no longer output after present or past malfunctions or both have been repaired, be sure to perform past malfunction display cancellation to prevent repair of malfunctions that have already been repaired. 2008 Mazda CX-9 Grand Touring 2008 RESTRAINTS On-Board Diagnostic (Restraints) - Mazda CX-9 Automotive-Manual.net
