Body Control Module: Diagnostic Aids
Checking Terminal Contacts
DESCRIPTION
When diagnosing an electrical system that utilizes Metri-Pack 150/280/480/630 series terminals (refer to Terminal Repair Kit, J 38125-A, J
38125-4 for terminal identification), it is important to check terminal contact between a connector and component, or between in-line connectors,
before replacing a suspect component.
Frequently, a diagnostic chart leads to a step that reads: Check for poor connection. Mating terminals must be inspected to assure good terminal
contact. A poor connection between the male and female terminal at a connector may be the result of contamination or deformation.
Contamination is caused by the connector halves being improperly connected, a missing or damaged connector seal, or damage to the connector
itself, exposing the terminals to moisture and dirt. Contamination, usually in underhood or underbody connectors, leads to terminal corrosion,
causing an open circuit or intermittently open circuit.
