Pinpoint Test M: DTC B0090:11 Or B0090:93

WARNING: This page is about a different car, the 2010 Mercury Milan, 2010 Lincoln MKZ, and 2010 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: 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.

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: Always make sure the correct SRS  component is being installed. Parts released for other vehicles may not be compatible even if they appear physically similar. Check the part number listed in the Ford Catalog Advantage™ or equivalent to make sure the correct component is being installed. If an incorrect SRS  component is installed, DTCs may set.
NOTE: The SRS  must be fully operational and free of faults before releasing the vehicle to the customer.
NOTE: Do not probe any impact sensor. The impact sensor can not be tested using a multi-meter.
  1. M1 RETRIEVE RCM DTCs 
    • Ignition ON.
    • Enter the following diagnostic mode on the scan tool: Self Test - RCM. 
    • Was DTC B0090:11 B0090:93 retrieved on-demand during self-test? 
    • Yes  : This fault cannot be cleared until it is corrected and the DTC is no longer retrieved on-demand during self-test.

      For DTC B0090:11, GO to M2  .
