PINPOINT TEST G: DTCs B1355 AND B1359 - IGNITION RUN CIRCUIT FAILURE AND IGNITION RUN/ACC CIRCUIT FAILURE

WARNING: This page is about a different car, the 2008 Ford Pickup, 2008 Ford F550 Super Duty, 2008 Ford F450 Super Duty, and 2008 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
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. G1 CHECK THE IGNITION SWITCH 
    • Key in OFF position.
    • Carry out the Ignition Switch Component Test. Refer to COMPONENT TESTING.
    • Is the ignition switch OK? 
    1. YES  : For DTC B1355, go to  G2.

      For DTC B1359, go to  G4.

    2. NO  : INSTALL a new ignition switch. REFER to Ignition Switch . CLEAR the DTCs . REPEAT the self-test.
  2. G2 CHECK CIRCUIT CDC63 (YE/OG) FOR AN OPEN 
    • Disconnect: Ignition Switch C250
    • Disconnect: CDIM C2500
      • Fig 1: Checking Circuit CDC63 (YE/OG) For An Open

    • Measure the resistance between ignition switch C250-7, circuit CDC63 (YE/OG), harness side and CDIM C2500-1, circuit CDC63 (YE/OG), harness side.
    • Is the resistance less than 5 ohms? 
    1. YES  : Go to  G3.
    2. NO  : REPAIR circuit CDC63 (YE/OG). CLEAR the DTCs. REPEAT the self-test.
  3. G3 CHECK CIRCUIT CDC63 (YE/OG) FOR A SHORT TO GROUND

    • Measure the resistance between ignition switch C250-7, circuit CDC63 (YE/OG), harness side and ground.
    • Is the resistance greater than 10,000 ohms? 
    1. YES  : Go to  G6.
    2. NO  : REPAIR circuit CDC63 (YE/OG). CLEAR the DTCs. REPEAT the self-test.
  4. G4 CHECK CIRCUIT CDC32 (BN/YE) FOR AN OPEN 
    • Key in OFF position.
    • Disconnect: CDIM C2500
    • Disconnect: SJB C2280A
      • Fig 3: Checking Circuit CDC32 (BN/YE) For An Open
      GF0049492Courtesy of FORD MOTOR CO.
    • Measure the resistance between CDIM C2500-8, circuit CDC32 (BN/YE), harness side and SJB C2280A-4, circuit CDC32 (BN/YE), harness side.
    • Is the resistance less than 5 ohms? 
    1. YES  : Go to  G5.
    2. NO  : REPAIR circuit CDC32 (BN/YE). CLEAR the DTCs. REPEAT the self-test.
  5. G5 CHECK CIRCUIT CDC32 (BN/YE) FOR A SHORT TO GROUND 
      Fig 4: Checking Circuit CDC32 (BN/YE) For A Short To Ground
      GF0049505Courtesy of FORD MOTOR CO.
    • Measure the resistance between CDIM C2500-8, circuit CDC32 (BN/YE), harness side and ground.
    • Is the resistance greater than 10,000 ohms? 
    1. YES  : Go to  G6.
    2. NO  : REPAIR circuit CDC32 (BN/YE). CLEAR the DTCs. REPEAT the self-test.
  6. G6 CHECK THE CDIM CONNECTORS 
    • Check the CDIM connector for:
      • corrosion.
      • pushed-out pins.
      • spread terminals.
    • Connect: CDIM C2500
    • Make sure the connector seats correctly, then operate the system and verify the concern is still present.
    • Is the concern still present? 
    1. YES  : INSTALL a new CDIM. REFER to Circuit Deactivation Ignition Module (CDIM) . CLEAR the DTCs. REPEAT the self-test.
    2. NO  : The system is operating correctly at this time. Concern may have been caused by a loose or corroded connector.
