Speaker Diagnostics

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.

The symptom chart below should be used when diagnosing speaker faults and must be worked through prior to replacing any speakers

REPORTED SYMPTOM SYMPTOM DESCRIPTION POTENTIAL CAUSES (FOR GUIDANCE ONLY) RECOMMENDED ACTION
  • Speaker Buzz
  • Periodic high frequency sound (sounds like an insect buzzing)
  • Resonance in a trim component, for example NVH (noise, vibration and harshness) insulating cloth against speaker grill mesh
  • Lack of retention of interior and exterior trim panels
  • Loose harness/harness clips
  • Labels vibrating against trim/nearby components
  • Nearby modules vibrating against trim/BIW
  • Mechanical failure of internal speaker component
  1. Replicate fault and confirm audio source(s) affected: DAB/CD/Bluetooth through phone/USB through phone/USB through iPod®/AM/FM radio
  2. If fault is specific to one source, audio source must be investigated further as a speaker failure in this instance is less likely, for example if issue is only seen on DAB, check DAB is fully functioning correctly and software is up to date
  3. Confirm if issue is heard on stereo and/or surround sound settings
  4. Isolate the customer symptom to specific vehicle area using balance and fade audio settings. Check for any loose objects in the area, for example pens, keys, coins, etc
  5. Check for any previous work completed in this area by referring to JLR claims submission system to help in diagnosing the issue
  6. Check SDD/Repair information for any audio related SSM/TSB and software updates. Complete service updates as required. Retest to confirm if issue is resolved
  7. Apply pressure by hand to door/trim panel and nearby modules (i.e. switchpacks) to confirm if there is a change in symptom sound
  8. If issue is still present, or condition changes by applying pressure to the trim, remove internal trim and apply gentle pressure to components within the door to see if sound changes. This will also allow access to relevant speaker
  9. If symptom condition is unchanged by applying pressure to the trim, examine trim to find source of audio issue and repair as appropriate using Squeaks and Rattle kit LTB00389. If audio issue is still present then move to step 10
  10. Check around front face of speaker for any loose items that may be touching the speaker, for example debris, loose fixings, etc
  11. Check all speaker fixing screws are secure and correctly torqued, refer to repair information for correct torque figures
  12. Check harness assembly is not vibrating against speaker unit or nearby trim/components and that it is clipped and routed correctly
  13. Check harness assembly is not trapped or impeding the speaker unit and rectify as required***
  14. Check ***are fully inserted and secured to speaker and amplifier. Also check harnesses are securely connected to nearby components
  15. Check for harness damage and repair/replace as required
  16. If a gasket is present on speaker, without removing the speaker visually check it is correctly seated against speaker surface and not noticeably damaged
  17. If audio issue is still present, remove speaker from mountings, retest speaker in hand to see if the fault is still present
  18. Check for debris in speaker and remove. Retest speaker in hand
  19. Check for damage to speaker and replace speaker if damage is present
  20. Connect new speaker to harness, check new speaker in hand to make sure the fault has been rectified. If issue has been resolved, reassemble trim with new trim retention clips
  21. Check if audio issue is still present. If issue has been resolved, reassemble trim and retest. If issue is still present, contact JLR Technical Assistance following the guidelines in the policy and procedures information
