SIR Connector/Terminal Position Assurance

Description:

CONNECTOR POSITION ASSURANCE (CPA)
The Connector Position Assurance (CPA) is a small plastic connector lock, located on the male connector half of the lower and upper steering column connectors and the passenger inflator module connector.

The CPA assures the following:
^ The connector halves are securely connected
^ The connector halves cannot vibrate apart
^ There is good contact between SRS mating terminals

TERMINAL POSITION ASSURANCE (TPA)
The Terminal Position Assurance (TPA) insert is similar to the plastic combs used in powertrain control module connectors. The function of the TPA is to keep the terminal securely seated in the connector body. Do not remove the TPA from the connector body unless a terminal must be removed for replacement.
