Pinpoint Test A : U3003:16 And U3003:17

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: 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: Install new components only when directed to do so in the pinpoint test.

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, Diagnostic Trouble Codes (DTCs) may set.

NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.

  CLEAR all Continuous Memory Diagnostic Trouble Codes (CMDTCs). If the battery passed the condition test and did not require a recharge, GO to A3
2. No: INSTALL a new battery.
  REFER to: Battery ( BATTERY ).
  
  CLEAR all Continuous Memory Diagnostic Trouble Codes (CMDTCs).
A3 CHECK THE CHARGING SYSTEM VOLTAGE
- Ignition ON.
- Measure the voltage of the battery.
- For DTC U3003:17, turn off all accessories while measuring the battery voltage.
- For DTC U3003:16, turn on headlights and HVAC fan on high while measuring the battery voltage.
Is the voltage between 13 and 15.2 volts?
1. Yes: For DTC U3003:16, GO to A4 For DTC U3003:17, GO to A6
2. No: Diagnose the charging system.
  REFER to: Charging System - 2.0L Duratec-HE ( CHARGING SYSTEM - 2.0L DURATEC-HE ).
  
  REFER to: Charging System - 2.0L EcoBoost ( CHARGING SYSTEM - 2.0L ECOBOOST ).

A4 CHECK FOR OPEN IGNITION CIRCUIT TO THE MODULE

Ignition OFF.
Depower the SRS. Refer to
REFER to: Supplemental Restraint System (SRS) Depowering and Repowering .
Disconnect OCSM C3159.
Disconnect RCM C310A and C310B.
For the RCM, measure:

Click to display connectors

Positive Lead	Measurement / Action	Negative Lead
C310A-24	Ω	Fuse 86 (10A)

For the OCSM, measure:

Click to display connectors

Positive Lead	Measurement / Action	Negative Lead
C3159-1	Ω	Fuse 86 (10A)

Is the resistance less than 1 ohm?

Yes: GO to A5
No: REPAIR the circuit as necessary.
Refer to OEM CONNECTOR REPAIR PROCEDURES for schematic and connector information.

CLEAR all Continuous Memory Diagnostic Trouble Codes (CMDTCs).

A5 CHECK FOR OPEN GROUND TO THE MODULE

For the RCM, measure:

Click to display connectors

Positive Lead	Measurement / Action	Negative Lead
RCM mounting bracket	Ω	-

For the OCSM, measure:

Click to display connectors

Positive Lead	Measurement / Action	Negative Lead
C3159-4	Ω	-

Is the resistance less than 1 ohm?

Yes: GO to A6
No: For the RCM, VERIFY there is no corrosion between the RCM and the mounting surface. VERIFY the fasteners are clean and tightened to specification with no corrosion. REPAIR as necessary.
Refer to OEM CONNECTOR REPAIR PROCEDURES for schematic and connector information.

For the OCSM, REPAIR the circuit.

Refer to OEM CONNECTOR REPAIR PROCEDURES for schematic and connector information.

CLEAR all Continuous Memory Diagnostic Trouble Codes (CMDTCs).

A6 CHECK FOR MODULE OPERATION
- Depower the SRS.
  REFER to: Supplemental Restraint System (SRS) Depowering and Repowering .
- Disconnect the module with the concern:
  - For the RCM, disconnect C310A and C310B (if not previously disconnected).
  - For the OCSM, disconnect OCSM C3159 (if not previously disconnected).
- Check for the following:
  - corrosion (install new connector or terminals - clean module pins)
  - damaged or bent pins - install new terminals/pins
  - pushed-out pins - install new pins as necessary
- Connect the module with the concern:
  - For the RCM, connect C310A and C310B. Make sure the connector seats correctly and engage Connector Position Assurance (CPA) lever/lock.
  - For the OCSM, connect OCSM C3159. Make sure the connector seats correctly.
- Repower the SRS. Do not prove out the SRS at this time.
  REFER to: Supplemental Restraint System (SRS) Depowering and Repowering .
- Operate the system and verify the concern is still present.
Is the concern still present?
1. Yes: CHECK OASIS for any applicable Technical Service Bulletins (TSBs). If a TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB instructions. If no Technical Service Bulletins (TSBs) address this concern, and DTC U3003:16 or U3003:17 was present in the RCM, INSTALL a new RCM. REFER to
  REFER to: Restraints Control Module (RCM) .
  
  If no Technical Service Bulletins (TSBs) address this concern, and DTC U3003:16 or U3003:17 was present in the OCSM, INSTALL a new OCSM.
