Stressing the mechanical connection of a connector
Pulling on the harness or wire in order to identify a separation/break inside the insulation
Relocating a harness or wires
All these actions should be performed with some goal in mind. For instance, with a scan tool connected, wiggling the wires may uncover a faulty input to
Certainly, using the senses of sight, smell, and hearing while manipulating the circuit can provide good results as well.
There may be instances where circuit manipulation alone will not meet the required criteria for the fault condition to appear. In such cases it may be
Salt Water Spray
Mixing 0.35L (12 oz) of water with approximately 1 tablespoon of salt will yield a salt solution of 5 percent. Fill a normal spray bottle with this
High Temperature Conditions
If the complaint tends to be heat related, you can simulate the condition using the J 25070.
Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring
The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable,
Low Temperature Conditions
If this is unsuccessful, use local cooling treatments such as ice or a venturi type nozzle (one that provides hot or cold air). This type of tool is capable
Once the vehicle, component, or harness has been sufficiently cooled, manipulate the harness or components in an effort to duplicate the concern.
NOTE: Refer to Test Probe Notice in Service Precautions.
The following procedure determines the frequency of a signal.
IMPORTANT: Connecting the DMM to the circuit before pressing the Hz button will allow the DMM to autorange to an appropriate range.
1. Apply power to the circuit.
