Live Probing On Sealed Connectors

WARNING: This page is about a different car, the 2018 Jaguar XE and 2017 Jaguar XE. However, it is still accessible from the selected car via links, so may be relevant.

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.
CAUTION: Before extracting any terminals, refer to the Electrical Connector Terminal Extraction and Extraction Tools in this information.

Extract the terminal to be tested from the electrical connector
Insert a substitute wire with 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.
