Pinpoint Test Bl : U1000:00
- Refer to SUPPLEMENTAL RESTRAINT SYSTEM
for schematic and connector information.
Normal Operation and Fault Conditions
The BECMB uses solid state drivers, referred to as Field Effect Transistors (FET) to control the output of several vehicle systems. When an overload occurs on any of these drivers, the BECMB disables the output and tracks the number of repetitive faults on each of these circuits. The module compares this number of overloads to three progressive thresholds established for each circuit. At each threshold, DTC U1000:00 sets along with the DTC associated with the affected circuit. For additional information, REFER to: Airbag and Seatbelt Pretensioner Supplemental Restraint System (SRS) - System Operation and Component Description .
DTC Fault Trigger Conditions
DTC Description Fault Trigger Condition BECMB U1000:00 Solid State Driver Protection Active -Driver Disabled: No Sub Type Information A continuous memory DTC that sets when the BECMB has disabled a circuit due to a repetitive circuit overload and a progressive threshold is met. Possible Sources
- BECMB output circuit short
- RCM
- OCSM
- WARNING: Do not handle, move or change the original horizontal mounting position of the Restraints Control Module (RCM) while the Restraints Control Module (RCM) is connected and the ignition switch is ON. Failure to follow this instruction may result in the accidental deployment of the Safety Canopy® and cause serious personal injury or death.
- 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: 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.
- BL1 CHECK FOR ADDITIONAL SRS (SUPPLEMENTAL RESTRAINT SYSTEM) DIAGNOSTIC TROUBLE CODES (DTCS)WARNING: Before beginning any service procedure in this information, refer to Safety Warnings in General Information. 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
Restraints self-test.
- Record the Diagnostic Trouble Codes (DTCs) that were retrieved.
Are any Diagnostic Trouble Codes (DTCs) present besides U1000:00?
Yes CORRECT the Diagnostic Trouble Codes (DTCs). REFER to RCM (DTC) Chart . No The system is operating correctly at this time. The DTC may have been set due to high network traffic or an intermittent fault condition.
