Live Probing On Sealed Connectors
WARNING: This page is about a different car, the 2020 Jaguar XE and 2019 Jaguar XE. However, it is still accessible from the selected car via links, so may be relevant.
WARNING:
- This procedure must never be done on any of the following. Failure to follow this instruction may result in personal injury;
- Supplementary 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 Control Module (ABS) and thermocouple circuits. An example of this is the ABS wheel speed sensors with molded connectors
- This procedure must only be done on wire with a cross sectional area of 0.5 mm squared or less.
CAUTION:
- The link lead used in this procedure must have a cross sectional area of at least 0.5 mm 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 articles of this document for more 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 1 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 substitute wire.
- Reconnect the electrical connector.
- Reconnect the battery ground cable and begin the test.
