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

Pinpoint Tests

Pinpoint Test K: LFC 42, 43, 44, 45 or 46 DTC B2296

Refer to Wiring Diagram Set 46, Supplemental Restraint System for schematic and connector information. Diagrams By Number

NOTE: Short to ground faults can be reported as a short to battery fault. Make sure to follow the pinpoint test as directed to correctly diagnose any short to ground faults retrieved during on-demand self test.

NOTE: When monitoring fault and/or resistance PIDs with the scan tool, it may take up to 2 seconds for the scan tool display to update.

NOTE: The first and second row side impact sensors are not interchangeable. First row side impact sensors are pressure sensors.

Normal Operation

The Restraints Control Module (RCM) continuously communicates with all impact sensors for external and internal sensor data. The RCM also continuously monitors all of the impact sensor circuits for a short to voltage, short to ground and open circuits. If the RCM detects any communication or circuit faults with any of the impact sensors, it will store DTC B2296 in memory and send a message to the Instrument Cluster (IC) module to flash, depending on the fault, either Lamp Fault Code (LFC) 42, 43, 44, 45, 46 or 47 on the air bag warning indicator.









a Fault PIDs that end in OD indicate an on-demand status and are associated with on-demand DTC B2296. Fault PIDs that end in CM indicate continuous memory status and are associated with continuous DTC B2296.

This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Impact sensor
- Incorrect sensor mounting
- RCM



PINPOINT TEST K: LFC 42, 43, 44, 45 or 46 DTC B2296

WARNING: Do not handle, move or change the original horizontal mounting position of the restraints control module (RCM) while the RCM is connected and the ignition switch is ON. Failure to follow this instruction may result in the accidental deployment of the Safety Canopy(R) and cause serious personal injury or death.

NOTICE: Use the correct probe adapter(s) from the Flex Probe Kit when taking 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. Inspection and Verification

NOTE: The Supplemental Restraint System (SRS) must be fully operational and free of faults before releasing the vehicle to the customer.

NOTE: 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: Do not probe any impact sensor. The impact sensor is an electronic device and cannot be tested using a multi-meter.
