hey how are you

It is a long test , but that is what you need to do to find out why , a capable scanner is necessary to do some steps of the test .

1- please review first 1st diagram listing possible cause .rest of diagram go with test steps below

Air Bag and Safety Belt Pretensioner Supplemental Restraint System (SRS)

Pinpoint Tests - Supplemental Restraint System (SRS)

Pinpoint Test E: DTC B2290

Refer to Wiring Diagram Set 46, Supplemental Restraint System for schematic and connector information. See: Vehicle > Electrical > Diagrams By Number

NOTE: DTC B2290 reported by the Restraints Control Module (RCM) indicates the presence of a fault in the Occupant Classification System Module (OCSM). The following pinpoint test must only be used to diagnose DTC B2290 when reported by the OCSM.

Normal Operation

The OCSM monitors the pressure sensor and circuity for faults. If the OCSM detects a fault, it will store DTC B2290 in memory and send a message to the RCM.

The RCM stores DTC B2290 in memory and sends a message to the Instrument Cluster (IC) module to illuminate the air bag warning indicator.

Zoom and Print Options

a Fault PIDs that end in OD indicate an on-demand status and are associated with on-demand DTC B2290. Fault PIDs that end in CM indicate continuous memory status and are associated with continuous DTC B2290. This pinpoint test is intended to diagnose the following: - Wiring, terminals or connectors - OCS system component - Pressure sensing fault - Module mounting PINPOINT TEST E: DTC B2290 WARNING: Never probe the electrical connectors on air bag, Safety Canopy(R) or side air curtain modules. Failure to follow this instruction may result in the accidental deployment of these modules, which increases the risk of serious personal injury or death. WARNING: Never disassemble or tamper with safety belt buckle/retractor pretensioners or adaptive load limiting retractors or probe the electrical connectors. Failure to follow this instruction may result in the accidental deployment of the safety belt pretensioners or adaptive load limiting retractors which increases the risk of serious personal injury or death. NOTICE: Use the correct probe adapter(s) from the Flex Probe Kit when making measurements. Failure to use the correct probe adapter(s) may damage the connector. Most faults are due to connector and/or wiring concerns. Carry out a thorough inspection and verification before proceeding with the pinpoint test. See: Air Bag Systems > Initial Inspection and Diagnostic Overview > Inspection and Verification NOTICE: It is necessary to carry out the Occupant Classification Sensor (OCS) system reset when a front passenger seat cushion is disassembled, a new trim cover is installed or an OCS system service kit is installed. A scan tool is used to carry out the OCS system reset. Failure to follow this instruction may result in system failure and the incorrect operation of the OCS system. NOTE: Supplemental Restraint System (SRS) components should only be disconnected or reconnected when instructed to do so within a pinpoint test step. Failure to follow this instruction may result in incorrect diagnosis of the SRS. NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer. ------------------------------------------------- E1 RETRIEVE OCSM DTCs - Enter the following diagnostic mode on the scan tool: Self Test - OCSM . - Enter the following diagnostic mode on the scan tool: DataLogger - OCSM - View and Record All 2290 Fault PIDs . - Refer to PID list in Normal Operation to view 2290 fault PIDs. - Do any OCSM on-demand 2290 fault PIDs indicate a fault?

Now the DTC B2292 is seat pretension er , did you replace that ,IN YOUR NOTES EARLIER NO MENTION ABOUT CHANGING THAT ,YOU WILL HAVE TO OR THE RCM WILL SEE IT AND KEEP SETTING THAT CODE FOR YOU

Air Bag and Safety Belt Pretensioner Supplemental Restraint System (SRS) Pinpoint Tests - Supplemental Restraint System (SRS) Pinpoint Test F: DTC B2292 Refer to Wiring Diagram Set 46, Supplemental Restraint System for schematic and connector information. See: Vehicle > Electrical > Diagrams By Number Normal Operation The Restraints Control Module (RCM) monitors all safety belt buckle pretensioner circuits for the following faults: - Resistance out of range - Unexpected voltage - Short to ground The RCM will set a DTC if a short to battery or short to ground fault is detected. The RCM will also set a DTC if the loop resistance is less than 0.9 ohm or greater than 5 ohms. The normal expected resistance range is 1.4 to 3.5 ohms. If resistance is between 0.9 and 1.4 ohms or between 3.5 and 5 ohms, there exists strong potential for an intermittent fault. If the RCM detects one of the following faults on either of the safety belt buckle pretensioner circuits, it will store DTC B2292 in memory and send a message to the Instrument Cluster (IC) module to illuminate the air bag warning indicator.

Please let me know IF THAT WORKS FOR YOU OR YOU NEED ANYTHING ELSE ON IT .
