X type jaguar 2008,My reversing lights and rear parking aid have stopped working ?

First you need to read the code's to find out what the problem is , you don't just guess and replace part's . You really should take it to a qualified repair shop if you don't know that .
Parking Aid The parking aid system consists of the:

• parking aid sensors
• parking aid speaker
• parking aid module

The parking aid system is activated when the parking aid module receives a network messages from the instrument cluster indicating that the vehicle is in reverse. The parking aid system sounds a warning to alert the driver of stationary objects near the rear bumper when REVERSE is selected. The parking aid system assists the driver in detecting certain objects while the vehicle moves in reverse at speeds less than 4.8 km/h (3 mph). The parking aid system may not detect angular or moving objects.

Inspection and Verification

1. Verify the customer concern.

1. Visually inspect the following for obvious signs of electrical damage.
   
   Visual Inspection Chart Electrical
   • Smart junction box (SJB) fuse 18 (10A)
   • Circuitry
   • Connector(s)
   • Parking aid sensors
   • Parking aid speaker
   • Parking aid module

1. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.

1. If the cause is not visually evident, connect the diagnostic tool to the data link connector (DLC) and select the vehicle to be tested from the diagnostic tool menu. If the diagnostic tool does not communicate with the vehicle:
   • check that the program card is correctly installed.
   • check the connections to the vehicle.
   • check the switch position.

1. If the diagnostic tool still does not communicate with the vehicle, refer to the diagnostic tool operating manual.

1. Carry out the diagnostic tool data link test. If the diagnostic tool responds with:
   • CAN circuit fault; all electronic control units no response/not equipped, refer to Section 418-00 .
   • No response/not equipped for parking aid module, Go To Pinpoint Test A .
   • System passed, retrieve and record the continuous diagnostic trouble codes (DTCs), erase the continuous DTCs and carry out self-test diagnostics for the parking aid module.

1. If the DTCs retrieved are related to the concern, go to the Instrument Cluster Diagnostic Trouble Code (DTC) Index or the Parking Aid Module Diagnostic Trouble Code (DTC) Index.

1. If no DTCs related to the concern are retrieved, GO to Symptom Chart . Instrument Cluster Diagnostic Trouble Code (DTC) Index DTC Description Source Action U0159 Lost Communication With Parking Aid Module Instrument Cluster REPAIR all other DTCs first. If the DTC is still present Go To Pinpoint Test A . All Other DTCs - Instrument Cluster REFER to Section 413-01 .

on a xj they are in the boxes by the light units ... X type iu dont know because i havent worked on one as yet?? as yet

HAVE SOMEONE GO BEHIND THE CAR AND CHECK AND MAKE SURE THE BRAKE LIGHTS ARE ON, IF THEY DON'T WORK THEN THERE IS NO POWER TO THE BRAKE PARK INTER-LOCK SOLENOID AND YOU CAN NOT DIS-ENGAGE PARK. IF THEY DON'T WORK CHECK THE FUSE, IF IT IS OK REPLACE THE BRAKE LIGHT SWITCH.
