Pinpoint Test - DTC: O. Diagnosis and Testing

B11D8:12 and B11D8:14

For circuit and connector information, refer to Wiring Diagrams Cell 46.

Normal Operation and Fault Symptoms

On vehicles equipped with a 1.0L Gasoline Turbocharged Direct Injection (GTDI) engine or a 1.6L GTDI engine, the RCM sends an event notification signal that communicates crash status and SRS deployment status to the FPDM. When the FPDM receives an event notification signal indicating a crash, it initiates a fuel shutoff.

On vehicles equipped with a 1.6 L Dual Independent Variable Camshaft Timing (Ti-VCT) engine, the RCM sends an event notification signal that communicates crash status and SRS deployment status to either the PCM or the FPDM, depending on the vehicle emissions equipment. When either module receives an event notification signal indicating a crash, it initiates a fuel shutoff.

The RCM monitors the event notification signal circuit for the following faults:

• Short to voltage
• Short to Ground
• Open circuit

When a fault is detected, the RCM stores DTC B11D8:12 or B11D8:14 in memory. The airbag warning indicator will not illuminate for B11D8:12 or B11D8:14.

DTC Fault Trigger Conditions

Possible Causes

• Wiring, Terminals or Connectors
• FPDM (vehicles equipped with 1.0L Gasoline Turbocharged Direct Injection (GTDI) engine, 1.6L GTDI engine, and some vehicles equipped with 1.6L Twin Independent Variable Cam Timing (Ti-VCT) engine)
• PCM (some vehicles equipped with 1.6 L Twin Independent Variable Cam Timing (Ti-VCT) engine)
• RCM

NOTE: Most concerns are related to connector and/or wiring issues. Perform a thorough inspection and check before proceeding to the Pinpoint Test.

NOTE: Only disconnect or reconnect SRS components when instructed to do so in the Pinpoint Test step. Failure to follow this instruction may result in an incorrect SRS diagnosis.

NOTE: Install new components only if directed by the pinpoint test.

NOTE: Always verify the correct SRS component is installed. Parts released for other vehicles may be incompatible even if they appear physically similar. Check the part number listed in the Ford parts catalog to confirm the correct component is installed. If an incorrect SRS component is installed, diagnostic trouble codes (DTCs) may be set.

NOTE: Before returning the vehicle to the customer, the SRS must be fully functional and operating correctly.

A1 REMOVE RCM (RESTRAINTS CONTROL MODULE) DIAGNOSTIC TROUBLE CODES (DTCS)

REFER TO: Pyrotechnic Device Handling Precautions (100-00 General Information, Description and Operation). The ignition is on. Using the diagnostic scan tool, perform the RCM self-test to retrieve diagnostic trouble codes (DTCs). Was DTC B11D8:12 or B11D8:14 retrieved on demand during the self-test? Yes This concern cannot be resolved until it is repaired and the DTC is no longer retrieved on demand during self-test. For DTC B11D8:14 GO to A2 For DTC B11D8:12 GO to A5 No This is an intermittent concern when present as a Continuous Memory Diagnostic Trouble Code (CMDTC) only. GO to A8
