Pinpoint Test N - DTC: B00C5:11, B00C5:12, B00C5:13, B00C5:1D

WARNING: This page is about a different car, the 2020 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.

Refer to Supplemental Restraint System for schematic and connector information.

Normal Operation and Fault Conditions

The RCM continuously monitors the passenger seat track position sensor circuits for the following faults:

Open circuit
Short to voltage
Short to ground
Current out of range
Faulted passenger seat track position sensor

If a fault is detected, the RCM stores DTC B00C5:11, B00C5:12, B00C5:13 or B00C5:1D in memory and sends a message to the IPC to illuminate the airbag warning indicator.

DTC Fault Trigger Conditions

DTC	Description	Fault Trigger Conditions
B00C5:11	Passenger Seat Track Position Restraints Sensor: Circuit Short to Ground	A fault is indicated when the RCM senses a short to ground on the passenger seat track position sensor circuit for more than 6 seconds.
B00C5:12	Passenger Seat Track Position Restraints Sensor: Circuit Short to Battery	A fault is indicated when the RCM senses a short to voltage on the passenger seat track position sensor circuit for more than 6 seconds.
B00C5:13	Passenger Seat Track Position Restraints Sensor: Circuit Open	A fault is indicated when the RCM senses an open on either passenger seat track position sensor circuit for more than 6 seconds.
B00C5:1D	Passenger Seat Track Position Restraints Sensor: Circuit Current Out of Range	A fault is indicated when the RCM measures current outside of an acceptable range on the passenger seat track position sensor circuit for more than 6 seconds.

Possible Sources

Inspect for loose or damaged connectors.

PINPOINT TEST A : B00C5:11, B00C5:12, B00C5:13 AND B00C5:1D

WARNING: Incorrect repair techniques or actions can cause an accidental Supplemental Restraint System (SRS) deployment. Never compromise or depart from these instructions. Failure to precisely follow all instructions could result in serious personal injury from an accidental deployment.
NOTE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may cause damage to the connector.
NOTE: Most faults are due to connector and/or wiring concerns. Carry out a thorough inspection and verification before proceeding with the pinpoint test.
NOTE: Only disconnect or reconnect SRS components 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 parts catalog to make sure the correct component is being installed. If an incorrect SRS component is installed, Diagnostic Trouble Codes (DTCs) may set.
NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.

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

WARNING: Before beginning any service procedure, refer to Safety Warnings. Failure to follow this instruction may result in serious personal injury.

REFER to: Pyrotechnic Device Health and Safety Precautions .

Ignition ON.

Using a diagnostic scan tool, perform RCM self-test.

Was DTC B00C5:11, B00C5:12, B00C5:13 and B00C5:1D retrieved on-demand during self-test?

Yes

If DTC U3003:16 or U3003:17 is also retrieved on-demand, REFER to Pinpoint Test - DTC: AN . If DTC U3003:16 or U3003:17 is not retrieved on-demand during self-test, DIAGNOSE the passenger seat track position sensor Diagnostic Trouble Codes (DTCs). This fault cannot be cleared until it is corrected and the DTC is no longer retrieved on-demand during self-test. For DTC B00C5:11 or B00C5:1D, GO to A2. For DTC B00C5:12, GO to A4. For DTC B00C5:13, GO to A5

If DTC U3003:16 or U3003:17 is also retrieved on-demand, REFER to Pinpoint Test - DTC: AN . If DTC U3003:16 or U3003:17 is not retrieved on-demand during self-test, DIAGNOSE the passenger seat track position sensor Continuous Memory Diagnostic Trouble Codes (CM DTCs). This is an intermittent fault when present as a CM DTC only. GO to A10

A2 CHECK THE PASSENGER SEAT TRACK POSITION SENSOR DTC (DIAGNOSTIC TROUBLE CODE) FOR A FAULT STATUS CHANGE (SHORT TO GROUND OR CURRENT OUT OF RANGE INDICATED)

NOTE: This pinpoint test step attempts to change the fault reported by the RCM by inducing a different fault condition. If the reported fault changes, this indicates the RCM is functioning correctly and is not the source of the fault.
