U0046-81 Definition: Vehicle Communication Bus C - Invalid serial data received Cause:
NOTE:
- Circuit reference - HS CAN H (CH) -
- Circuit reference - HS CAN L (CH) -
Diagnosis:
- Invalid data received from another control module through the high speed CAN bus (chassis)
- Using the Jaguar Land Rover approved diagnostic equipment, check the snapshot data to determine the invalid data source control module. Check the relevant control module for related Diagnostic Trouble Code(s) and refer to the relevant DTC index
- CAUTION: This procedure requires a minimum of Pathfinder 277 loaded or later
Code: U2300-55 Definition: Central Configuration - Not configured Cause:
NOTE: When the ignition is switched on, if the warning indicator flashes for 75 seconds then remains illuminated a system fault is present
Diagnosis:
- Car configuration file mismatch with vehicle specification
NOTE: After updating the car configuration file, set the ignition to on and wait 30 seconds before clearing the DTCs
TOPix - SSM72877 - The BCM shows four Critical mismatches in the CCF Page I of I
- Using the Jaguar Land Rover approved diagnostic equipment, re-configure the central junction box with the latest level software

000101 Diagnostic Concerns
After completing any modification to the Car Configuration File (CCF) on the vehicles
mentioned in this SSM either of the two issues below can occur:
• The Diagnostic Trouble Codes (DTCs) U2300-62 or U2300-54 is stored in the Body
Control Module (BCM).
• The CCF loaded into the BCM contains four critical mismatches related to the CCF
assemblies for different modules.
Code: U3001-46 Definition: Control Module Improper Shutdown - Calibration/parameter memory failure Cause:
Diagnosis:
- Event information
- Driver/passenger seat module power has been disconnected whilst in manufacturing mode
NOTE: Do NOT replace the module to repair this DTC
- Using the Jaguar Land Rover approved diagnostic equipment, check the snapshot data (0x4237) to identify the lost calibration axes
- If the front seat axes have lost calibration, using the Jaguar Land Rover approved diagnostic equipment, perform routine - Calibration Run (0x205F). Clear the Diagnostic Trouble Code(s) and retest
- If the rear seat axes have lost calibration, using the Jaguar Land Rover approved diagnostic equipment, perform routine - Calibration Run (0x2055). Clear the Diagnostic Trouble Code(s) and retest.
Crist your boringSo, according to your source, these are to be ignored?
All (IMO) point to valid issues and would be treated as confirmed concerns for warranty purposes, with corrective action taken and charged out. Certainly not 'clear & ignore' at least two point to loss of functionality, one would qualify for 'further investigation.
in first place I started buying the kit contents polybush for landrover discovery 5 L462 and replacing it with the rubber parts in orange as seen in the photo. i changed the rubber part in the upper swingarm and there was a suspension sensor for the regulation of the hight that i removed and placed it back right because i couldnt work without removing it (maybe i did something wrong by touching the sensor is that right?). after that i saw the error after the diagnosis as i writed in the first thread and i saw in the display that the hight was only available in normal and the driving was terrible. the car was moving like in a ship and the level of the suspension was in the normal hight. the display also showed a sign fault and below it, it says, only normal hight is available. is that enough information for you to understand? i hope yes.Well the first thing is 'what the hell have you done there? and why?'
You need to be specific about which systems are reporting the 'U' codes, the B141296 is easy, that's the Quiescent control module, it's a grey box in the right rear quarter behind the trim with some fuses in it - looks like an auxiliary fuse box. - the other codes may be related to loss of communication with it, until you tell us more detail it's impossible to say.
there was an issue on discovery three and four with fitting poly bushes they were too stiff and had too much stiction caused various suspension codes to come to light.in first place I started buying the kit contents polybush for landrover discovery 5 L462 and replacing it with the rubber parts in orange as seen in the photo. i changed the rubber part in the upper swingarm and there was a suspension sensor for the regulation of the hight that i removed and placed it back right because i couldnt work without removing it (maybe i did something wrong by touching the sensor is that right?). after that i saw the error after the diagnosis as i writed in the first thread and i saw in the display that the hight was only available in normal and the driving was terrible. the car was moving like in a ship and the level of the suspension was in the normal hight. the display also showed a sign fault and below it, it says, only normal hight is available. is that enough information for you to understand? i hope yes.View attachment 322725View attachment 322726View attachment 322727
