Live Probing On Sealed Connectors

WARNING:

This procedure must never be carried out on any of the following. Failure to follow this instruction may result in personal injury;
- Supplemental Restraint System (SRS)
- Pedestrian protection system
- Throttle Control circuits
- Speed Control circuits
- Link lead assembles, which are unique to safety critical circuits such as Anti-lock Brake System (ABS) and thermocouple circuits. An example of this is the ABS wheel speed sensors with molded connectors
This procedure must only be carried on wire with a cross sectional area of 0.5mm squared or less.

CAUTION:

The link lead used in this procedure must have a cross sectional area of at least 0.5mm squared.
The battery ground cable must be disconnected before any electrical connectors are disconnected/reconnected.

Disconnect the battery ground cable, refer to Battery Disconnect And Connect (G1033944) .
CAUTION: Before extracting any terminals, refer to the Electrical Connector Terminal Extraction and Extraction Tools sections of this document for more information.

Extract the terminal to be tested from the electrical connector
Insert a substitute wire with the the same terminal and cross sectional area of the previously extracted wire, into the vacated position of the electrical connector.
CAUTION: The link lead clip must only be attached to the portion of the extracted terminal; that is crimped directly to the section of non-insulated wire.

Attach one end of the link lead to the original wire terminal.
CAUTION: The link lead clip must only be attached to the non-insulated section of the wire.

Attach the remaining end of the link lead to the substite wire.
Reconnect the electrical connector.
Reconnect the battery ground cable and begin the test. Refer to Battery Disconnect And Connect (G1033944) .
