System Diagnostics For Parking Aid And Park Assist

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.

If the On-Board Diagnostic (OBD) system identify a fail, the following warnings will be apply:

The IC displays an error message.
The front audio system speakers will emit a three second continuous tone.
A Diagnostic Trouble Code (DTC) is logged in the Parking Aid Control Module (PACM) module.

The PACM has a diagnostic connection via the HS CAN chassis systems bus to enable faults to be retrieved using the Jaguar approved diagnostic equipment. Additionally an OBD routine within the PACM constantly monitors the system and alerts the driver to a system fault by emitting a three second continuous tone through the front audio speakers when the ignition is switched on. The control switch Light Emitting Diode (LED) will also flash 6 times when reverse gear is selected or the parking aid system switch is pressed.
