  1. M1 VERIFY ALL WIRING CONNECTIONS 
    • Ignition OFF.
    • Disconnect ABS  module C135  .
    • Disconnect brake booster vacuum sensor C149  .
    • Using a good light source, inspect each connector terminal for any corrosion.
    • Inspect both connectors for any pushed-out pins.

      Refer to OEM CONNECTOR REPAIR PROCEDURES -- (EXCEPT HYBRID) for additional information.

    • Using a suitable mating terminal, check each female terminal for deformed or enlarged contacts by comparing the mating terminal's fit between each of the following pins:

      C135-36 

      C135-44 

      C135-45 

      C1603-1 

      C1603-2 

      C1603-3 

    Are both connectors free of corrosion, pushed-out pins and deformed or enlarged contacts? 

    1. Yes  : GO to M2 
    2. No  : REPAIR the affected terminal.
  2. M2 CHECK THE ABS (ANTI-LOCK BRAKE SYSTEM) MODULE DIAGNOSTIC TROUBLE CODES (DTCS) 
    • Connect ABS  module C135  .
    • Connect brake booster vacuum sensor C149  .
    • Ignition ON.
    • Using a diagnostic scan tool, carry out the ABS  module self-test.

    Is DTC C0047:26 present? 

    1. Yes  : GO to M3 
    2. No  : For C0047:01, C0047:1B, C0047:27 and C0047:62, GO to  M4

      For all other ABS  module codes, GO to the DTC CHART: ANTI-LOCK BRAKE SYSTEM (ABS) MODULE .

  3. M3 CHECK THE BRAKE BOOSTER AND VACUUM HOSES FOR LEAKS 
    • Inspect the vacuum hoses, brake booster and brake booster seals for leaks or evidence of leaks.

    Are any leaks or evidence of leaks found? 

    1. Yes  : REPAIR or INSTALL new components as necessary.
    2. No  : GO to M4 
  4. M4 CHECK THE VACUUM SENSOR WIRING FOR A SHORT TO VOLTAGE 
    • Ignition OFF.
    • Disconnect ABS  module C135  .
    • Disconnect brake booster vacuum sensor C149  .
    • Ignition ON.
    • Measure:
      Positive Lead Measurement/Action Negative Lead
      C135-36  VOLTAGE Ground
      C135-44  VOLTAGE Ground
      C135-45  VOLTAGE Ground

    Is any voltage present? 

    1. Yes  : REPAIR the affected circuit.
    2. No  : GO to M5 
  5. M5 CHECK THE VACUUM SENSOR WIRING FOR A SHORT TO GROUND 
    • Ignition OFF.
    • Measure:
      Positive Lead Measurement/Action Negative Lead
      C135-36  OHM Ground
      C135-44  OHM Ground
      C135-45  OHM Ground

    Are the resistances greater than 10, 000 ohms? 

    1. Yes  : GO to M6 
    2. No  : REPAIR the affected circuit.
  6. M6 CHECK THE VACUUM SENSOR WIRING FOR AN OPEN 
    • Measure:
      Positive Lead Measurement/Action Negative Lead
      C135-36  OHM C149-1 
      C135-44  OHM C149-3 
      C135-45  OHM C149-2 

    Are the resistances less than 3 ohms? 

    1. Yes  : GO to M7 
    2. No  : REPAIR the affected circuit.
  7. M7 CHECK THE VACUUM SENSOR WIRING FOR A SHORT TOGETHER 
    • Measure:
      Positive Lead Measurement/Action Negative Lead
      C149-1  OHM C149-2 
      C149-1  OHM C149-3 
      C149-2  OHM C149-3 

    Are the resistances greater than 10, 000 ohms? 

    1. Yes  : GO to M8 
    2. No  : REPAIR the affected circuit.
  8. M8 CHECK THE ABS (ANTI-LOCK BRAKE SYSTEM) MODULE OUTPUT 
    • Connect ABS  module C135  .
    • Ignition ON.
    • Measure:
      Positive Lead Measurement/Action Negative Lead
      C149-3  VOLTAGE Ground

    Is the approximately 4.7 volts? 

    1. Yes  : INSTALL a new brake booster.

      REFER to: BRAKE BOOSTER .

    2. No  : GO to M9 
  9. M9 CHECK FOR CORRECT ABS (ANTI-LOCK BRAKE SYSTEM) MODULE OPERATION 
    • Ignition OFF.
    • Disconnect and inspect ABS  module C135  .
    • Repair:

      corrosion (install new connector or terminal - clean module pins)

      damaged or bent pins - install new terminals or pins

      pushed-out pins - install new pins as necessary

    • Connect ABS  module C135  . Make sure it seats and latches correctly.
    • Connect brake booster vacuum sensor C149  .
    • Operate the system and determine if the concern is still present. Make sure it seats and latches correctly.

    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 the TSB  instructions. If no Technical Service Bulletins (TSBs) address this concern, INSTALL a new ABS  module and HCU  assembly.

      REFER to: HYDRAULIC CONTROL UNIT (HCU)  .

    2. No  : The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. ADDRESS the root cause of any connector or pin issues.
