PINPOINT TEST C: DTCs U3004:11, 12 and 13

NOTE: Use the Flex Probe Kit for all test connections to prevent damage to the wiring terminals. Do not use standard multi-meter probes.
  1. C1 CHECK THE RFA MODULE FOR DTCs 
    • Review the DTCs retrieved and recorded during Inspection and Verification.
    • Is DTC U3004:11, 12 or 13 present? 
    • Yes  : For U3004:11, GO to C2.

      For U3004:12, GO to  C3.

      For U3004:13, GO to  C6.

    • No  : For all other RFA module DTCs, REFER to the Master DTC Table in MULTIFUNCTION ELECTRONIC MODULES article.
  2. C2 CHECK THE IGNITION ACC CIRCUIT FOR A SHORT TO GROUND 
    • Ignition OFF.
    • Disconnect: RFA Module C2153B.
    • Disconnect: SJB C2280A.
    • Measure the resistance between SJB C2280A-3, circuit CDC33 (VT/GN), harness side and ground.

    • Is the resistance greater than 10, 000 ohms? 
    • Yes  : GO to  C7.
    • No  : REPAIR circuit CDC33 (VT/GN). CARRY OUT an on-demand self test (required to clear certain DTCs). CORRECT any unresolved DTCs. CLEAR all DTCs. TEST the system for normal operation.
  3. C3 CHECK THE IGNITION ACC CIRCUIT FOR A SHORT TO VOLTAGE 
    • Ignition OFF.
    • Disconnect: RFA Module C2153B.
    • Disconnect: SJB C2280A.
    • Ignition ON.
    • Measure the voltage between RFA module C2153B-4, circuit CDC33 (VT/GN), harness side and ground.

    • Is any voltage present? 
    • Yes  : REPAIR circuit CDC33 (VT/GN). CARRY OUT an on-demand self test (required to clear certain DTCs). CORRECT any unresolved DTCs. CLEAR all DTCs. TEST the system for normal operation.
    • No  : GO to C4.
  4. C4 CHECK SJB FUSE 43 (10A) OUTPUT CIRCUIT FOR A SHORT TO VOLTAGE 
    • Ignition OFF.
    • Disconnect: SJB Fuse 43 (10A).
    • Ignition ON.
    • Measure the voltage between ground and:
      • SJB fuse 43 (10A), input side.
      • SJB fuse 43 (10A), output side.

    • Is any voltage present? 
    • Yes  : If voltage is present on SJB fuse 43 (10A), output side, REPAIR circuit CBP43 (GY).

      If voltage is present on the input side of SJB fuse 43 (10A), INSTALL a new SJB. REFER to MULTIFUNCTION ELECTRONIC MODULES article. CARRY OUT an on-demand self test (required to clear certain DTCs). CORRECT any unresolved DTCs.

      CLEAR all DTCs. TEST the system for normal operation.

    • No  : GO to C5.
  5. C5 CHECK SJB FUSE 45 (5A) OUTPUT CIRCUIT FOR A SHORT TO VOLTAGE 
    • Ignition OFF.
    • Disconnect: SJB Fuse 45 (5A).
    • Ignition ON.
    • Measure the voltage between ground and:
      • SJB fuse 45 (5A), input side.
      • SJB fuse 45 (5A), output side.

    • Is any voltage present? 
    • Yes  : If voltage is present on SJB fuse 45 (5A), output side, REPAIR circuit CBP45 (YE).

      If voltage is present on the input side of SJB fuse 45 (5A), INSTALL a new SJB. REFER to MULTIFUNCTION ELECTRONIC MODULES article. CARRY OUT an on-demand self test (required to clear certain DTCs). CORRECT any unresolved DTCs.

      CLEAR all DTCs. TEST the system for normal operation.

    • No  : GO to C6.
  6. C6 CHECK THE IGNITION ACC CIRCUIT FOR AN OPEN 
    • Ignition OFF.
    • Disconnect: RFA Module C2153B.
    • Disconnect: SJB C2280A.
    • Measure the resistance between SJB C2280A-3, circuit CDC33 (VT/GN), harness side and RFA module C2153B-4, circuit CDC33 (VT/GN), harness side.
