Diagnosis & Testing
  1. Check the wiring harness, connectors and ground connections.
  2.  
  3. Measure voltage to check for open circuits by performing the following:
    1. Engage the load
    2.  
    3. Set the multi-meter to voltage measurement and connect its minus cable to a good grounding point
    4.  
    5. Connect the voltmeter positive cable to the point where the voltage is to be tested
    6.  
    7. On the output side of a switch/control module, it is best to start there and then gradually move out towards the load
    8.  
    9. The break point in the circuit has been passed when the voltage disappears
    10.  
    11. On the input side of a switch/control module/consumer, it is best to start at the closest point to the power source (often the fuse) and then gradually move towards the switch/control module/consumer
    12.  
    13. The break point in the circuit has been passed when the voltage disappears
    14.  

  4.  
  5. Measure resistance to check for open circuits by performing the following:
    1. Make sure the component or lead being tested is not carrying a current (e.g. by removing the associated fuse)
    2.  
    3. Set the multi-meter to resistance measurement and connect it across the component/lead being tested
    4.  
    5. Move the wiring harness in question while observing the ohmmeter
    6.  
    7. The resistance of the wiring harness should normally be less than 1 ohm. A specified value applies to components
    8.  

  6.  
  7. Check for short circuits to ground by performing the following:
    1. Make sure the lead being tested is not carrying a current (e.g. by removing the associated fuse) and that any load has been disengaged
    2.  
    3. Set the multi-meter to resistance measurement
    4.  
    5. Connect one test cable to a good ground and the other to the point to be tested
    6.  
    7. Carefully move the wiring harness and make sure the multi-meter shows infinite resistance (OL) the whole time
    8.

  9. Check components connectivity and functionality. Replace components as necessary.
