PINPOINT TEST H: DTCs U2060 AND 2062 - ECU REDUNDANT POWER CIRCUIT OR GROUND CIRCUIT OPEN

WARNING: This page is about a different car, the 2008 Mercury Mariner and 2008 Ford Escape. 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. H1 CHECK THE ABS MODULE POWER SUPPLY 
    • Key in OFF position.
    • Disconnect: ABS Module C1462
    • Key in ON position.
    • Measure the voltage between ground and:
      • ABS module C1462-1, circuit SBB09 (RD), harness side.
      • ABS module C1462-17, circuit SBB06 (BN/RD), harness side.
      • ABS module C1462-29, circuit CBP34 (VT/BN), harness side.
      • ABS module C1462-32, circuit SBB18 (YE/RD), harness side.
      • Fig 1: Measuring Voltage

    • Are the voltages greater than 10 volts? 
    1. YES  : Go to  H2.
    2. NO  : INSPECT BJB fuses 6 (5A), 9 (50A), 18 (50A) and/or SJB fuse 34 (5A). If OK, REPAIR the affected circuit(s). REPEAT the self-test.
  2. H2 CHECK CIRCUITS GD113 (BK/YE) AND GD179 (BK/VT) FOR AN OPEN 
    • Key in OFF position.
    • Measure the resistance between ground and:
      • ABS module C1462-16, circuit GD179 (BK/VT), harness side.
      • ABS module C1462-47, circuit GD113 (BK/YE), harness side.
      • Fig 2: Measuring Resistance

    • Are the resistances less than 5 ohms? 
    1. YES  : Go to  H3.
    2. NO  : REPAIR the affected circuit(s). REPEAT the self-test.
  3. H3 CHECK FOR CORRECT ABS MODULE OPERATION 
    • Check the ABS module connector for:
      • corrosion.
      • pushed-out pins.
      • spread terminals.
    • Connect the ABS module connector and make sure it is seated correctly.
    • Operate the system and verify the concern is still present.
    • Is the concern still present? 
    1. YES  : INSTALL a new HCU. REFER to Hydraulic Control Unit (HCU) - Hybrid . TEST the system for normal operation.
    2. NO  : The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. CLEAR the DTCs. REPEAT the self-test.
