Causes

  • Navigation module internal failure
  • Loss of power or ground to the navigation module (blown fuse, poor connector)
  • Faulty or corroded connectors/wiring between the module and vehicle network
  • CAN/MOST/LIN bus or gateway communication fault
  • Software corruption or failed module update
  • Vehicle battery low or unstable voltage during module wake-up

Symptoms

  • Navigation functions unavailable or frozen
  • No navigation unit shown on diagnostic tool or 'module not present' messages
  • Infotainment/display showing communication error or blank screen
  • Loss of GPS guidance, maps, or route calculation
  • Possible related network errors or other modules reporting U-codes

What to check

  • Read all stored DTCs and freeze frame with a compatible Land Rover diagnostic tool
  • Check vehicle battery voltage and state of charge
  • Inspect fuses and power/ground circuits for the navigation module
  • Visually inspect connectors and wiring for damage, corrosion or water ingress
  • Check for other network-related U-codes that indicate bus-wide faults
  • Verify module presence and CAN/MOST node list using diagnostic tool

Signal parameters

  • CAN bus voltage idle: ~2.5 V (verify CAN_H/CAN_L differential signals)
  • CAN message IDs and frequencies for navigation node (see manufacturer list)
  • Module supply voltage (key on): battery voltage within specification
  • Ground resistance:
  • Bus error counters / bus-off status reported by gateway or scan tool

Diagnostic algorithm

  1. Connect a Land Rover-compatible scan tool and record U2613 plus any related codes and freeze frame data.
  2. Verify battery voltage is within specification; if low, charge battery before further testing.
  3. Check fuses and power/ground feeds to the navigation module; repair any open circuits.
  4. Visually inspect and reseat the navigation module connector(s); look for bent pins, corrosion, or water damage.
  5. Use the scan tool to confirm whether the navigation module responds to requests (module present/absent).
  6. If the module is absent, check continuity and short tests on the communication bus wiring (CAN/MOST/LIN as applicable).
  7. Monitor CAN/MOST signals with an oscilloscope or diagnostic tool to identify noise, short to ground/Vbatt, or bus-off conditions.
  8. If wiring and power are good but still no response, attempt a soft reset/clear DTCs and power-cycle the module. Re-check communications.
  9. Check for and apply any available software updates or reflash the navigation module per manufacturer procedure.
  10. If fault persists and all wiring/power/software checks are good, consider replacement of the navigation module or gateway; program and initialise replacement as required.
  11. After repair, clear DTCs and confirm normal communications and operation; perform a road test of navigation functions.

Likely causes

  • Blown fuse or disconnected power/ground to navigation unit
  • Damaged or loose connector at the navigation module
  • Fault on the vehicle communication bus (CAN high/low short/open)
  • Navigation module software fault requiring reflash or reinitialisation
  • Gateway/module addressing/initialisation issue after replacement or battery disconnect
