      • Does the part number in the Restraints Control Module (RCM) match the part number listed in the parts catalog? 
      1. Yes:  GO to 5  on page 3.
      2. No:  INSTALL the correct Restraints Control Module (RCM). REFER to RESTRAINTS CONTROL MODULE (RCM) .
  5. CHECK THE PRIVATE High Speed Controller Area Network (HS-CAN) CIRCUITS FOR A SHORT TO VOLTAGE
    1. Depower the Supplemental Restraint System (SRS). REFER to SUPPLEMENTAL RESTRAINT SYSTEM (SRS) DEPOWERING AND REPOWERING - WITH INTELLIGENT ACCESS (IA) or REFER to SUPPLEMENTAL RESTRAINT SYSTEM (SRS) DEPOWERING AND REPOWERING - WITHOUT INTELLIGENT ACCESS (IA) .
    2. Disconnect Restraints Control Module (RCM) C310B.
    3. Disconnect Anti-Lock Brake System (ABS) Module electrical connector.
    4. Repower the Supplemental Restraint System (SRS). Do not prove out the Supplemental Restraint System (SRS) at this time. REFER to SUPPLEMENTAL RESTRAINT SYSTEM (SRS) DEPOWERING AND REPOWERING - WITH INTELLIGENT ACCESS (IA) or REFER to SUPPLEMENTAL RESTRAINT SYSTEM (SRS) DEPOWERING AND REPOWERING - WITHOUT INTELLIGENT ACCESS (IA) .
    5. Ignition ON.
    6. Measure:

      • Is any voltage present? 
      1. Yes:  REPAIR the affected circuit(s).
      2. No:  GO to 6  on page 4.
  6. CHECK THE PRIVATE High Speed Controller Area Network (HS-CAN) CIRCUITS FOR A SHORT TO GROUND
    1. Ignition OFF.
    2. Measure:
      Fig 2: Checking Private High Speed Controller Area Network (HS-CAN) Circuits For Short To Ground
      G07420362Courtesy of FORD MOTOR CO.
      • Are the resistances greater than 10,000 ohms? 
      1. Yes:  GO to 7  on page 5.
      2. No:  REPAIR the affected circuit(s).
  7. CHECK THE PRIVATE High Speed Controller Area Network (HS-CAN) CIRCUITS FOR A SHORT TOGETHER
    1. Measure:
      Fig 3: Checking Private High Speed Controller Area Network (HS-CAN) Circuits For Short Together
      G07420363Courtesy of FORD MOTOR CO.
      • Is the resistance greater than 10,000 ohms? 
      1. Yes:  GO to 8  on page 6.
      2. No:  REPAIR the affected circuit(s).
  8. CHECK THE PRIVATE High Speed Controller Area Network (HS-CAN) CIRCUITS FOR AN OPEN
    1. Measure:
      Fig 4: Checking Private High Speed Controller Area Network (HS-CAN) Circuits For Open
      G07420364Courtesy of FORD MOTOR CO.
      • Are the resistances less than 3 ohms? 
      1. Yes:  GO to 9  on page 7.
      2. No:  REPAIR the affected circuit(s).
  9. CHECK FOR CORRECT Restraints Control Module (RCM) OPERATION
