2018 Jaguar E-PACE Audio Control Module: Fixing Black Screens & No-Sound Glitches
This guide covers the common software-related failures of the 2018 Jaguar E-PACE audio system and explains the critical programming required when replacing the module.
- A replacement Audio Control Module (new or used) is NOT plug-and-play and MUST be programmed to the vehicle's VIN by a dealer or specialist with JLR software.
- Most common symptoms like a black screen or no sound are caused by software glitches; always try a system reset and check for available software updates before replacing hardware.
- The main module, called the Infotainment Master Controller (IMC), is located in the left side of the trunk, not behind the dashboard screen.
- Before condemning the module, ensure the vehicle's 12V battery is fully charged and in good condition, as low voltage is a known cause of infotainment problems.
Symptoms of a Failing Audio Control Module
Failures in the 2018 E-PACE audio control module almost always appear as software glitches rather than a complete, permanent hardware failure. These issues are often intermittent and can sometimes be temporarily fixed by restarting the vehicle. Because the module controls more than just sound, a failure can affect multiple systems.
- No Sound: The most common symptom is a total loss of audio. This includes the radio, Bluetooth, USB media, and even system sounds like parking sensor beeps and navigation voice prompts. The screen may show that music is playing, but no sound comes from the speakers.
- Black or Frozen Screen: The main 10-inch infotainment display may go completely black, freeze on the Jaguar logo, or become unresponsive to touch. This can happen on startup or randomly while driving.
- Endless Rebooting: The system may get stuck in a boot loop, where the Jaguar logo appears and then the system restarts repeatedly without ever reaching the home screen.
- System Lag or Slow Response: The unit may be extremely slow to boot up or respond to commands, a problem that can be worse on cold starts.
- Loss of Features: Functions like Bluetooth connectivity, navigation, or Apple CarPlay/Android Auto may fail to launch or work intermittently.
Technicians diagnosing this issue will often look for Diagnostic Trouble Codes (DTCs). The most common codes associated with a failing audio module are U-codes, which indicate a loss of communication on the vehicle's data network.
- U0156: Lost Communication with Information Centre 'A'
- U1A15-87: Incomplete MOST ring reported by infotainment control module
- U1A24-00: MOST ring complete no communication
Pro Tip: Before assuming the module is bad, perform a soft reset by pressing and holding the radio power/volume knob for 15-30 seconds until the screen restarts. Also, check that the vehicle's battery is fully charged and in good health, as low voltage can cause a wide range of electronic issues in Jaguars.
Known Issues, TSBs, and Software Updates
The InControl Touch Pro system in the 2018 E-PACE is known for being buggy. Jaguar Land Rover (JLR) has released numerous software updates to address these problems. In many cases, a software update performed by a dealer can resolve issues like a black screen or no audio without needing to replace any hardware.
Jaguar issued Technical Service Bulletin (TSB) SSM74490 in July 2019 specifically for a condition where "no audio can be heard in the vehicle." Another TSB, H142NAS1, provided a software update for the InControl Touch Pro system to fix various bugs on 2019 models, which share the same architecture. These bulletins confirm that Jaguar is aware of these software-based problems and the primary fix is a software re-flash.
Warning: Always have a dealer or qualified shop check for available software updates before paying to replace the Audio Control Module. Many reported problems can be fixed with a software update alone.
Buying a Used Audio Control Module
For buyers of used parts, the Audio Control Module presents a significant challenge. While a used OEM module is a cost-effective alternative to a new one, it is not a simple plug-and-play part.
1. Part Number Verification is Critical: The E-PACE was available with different sound systems (base, Meridian, Meridian Surround), and each may use a different module. You MUST match the part number from your original module exactly. The part number is printed on a sticker on the module's case. Common part numbers include J9C11412, J9C319C216NA, J9C319C216SA, JW9319C211NA, and JW9319C211SA.
2. Programming is MANDATORY: A used Audio Control Module (IMC) will not work correctly until it is programmed to your vehicle's VIN and its specific equipment list. This process involves editing the Car Configuration File (CCF) using specialized diagnostic tools like JLR Pathfinder or SDD. Without this step, the module will not be able to communicate with the other systems in the car.
3. Factor in Programming Costs: When buying a used module, you must account for the additional cost of programming, which can be several hundred dollars. This service can be performed by a Jaguar dealer or an independent European auto specialist who has the proper JLR-specific equipment and subscriptions.
4. Physical Inspection: When you receive a used module, inspect the casing for any signs of damage or water intrusion. Check that all connector pins are straight and free of corrosion. Since these are complex electronic units, there is always a risk of receiving a defective part, so purchase from reputable sellers with a warranty.
Cost to Replace the 2018 E-PACE Audio Control Module
The cost to fix an audio system issue can vary dramatically depending on whether the problem is software or a failed module.
| Item | Estimated Cost |
|---|---|
| Software Update/Reprogram at Dealer | $200 - $400 |
| New OEM Module (Part Only) | $2,100 - $2,300 |
| Used OEM Module (Part Only) | $250 - $600 |
| New Aftermarket / Remanufactured | Not Available |
| Shop Labor (Physical Install) | $150 - $250 (1-2 hours) |
| Shop Labor (Programming New/Used Module) | $200 - $400 (1-2 hours) |
Replacement Procedure Overview & Module Location
The main Audio Control Module (Infotainment Master Controller/IMC) is located in the left side of the trunk/boot compartment, behind the trim panel. It is not behind the dashboard screen.
- Disconnect the vehicle's battery.
- Open the trunk and remove the left-side cargo area trim panel to access the electronics rack.
- The IMC is one of the modules in this rack. Identify it and disconnect the electrical connectors and fiber optic (MOST) cables.
- Unbolt the module from its mounting bracket.
- Installation is the reverse of removal.
Warning: The fiber optic cables (MOST ring) are fragile. Do not bend them sharply or force the connectors. A break in the fiber optic loop will cause the entire infotainment system to fail.
After physical installation, the vehicle must be taken to a dealer or specialist for programming.
Frequently Asked Questions (FAQ)
Does a used 2018 E-PACE audio module need to be programmed?
Yes, absolutely. A replacement module, whether new or used, must be programmed to your car's specific VIN and options using Jaguar's diagnostic software. It is not a plug-and-play part.
My infotainment screen is black. Is the audio module definitely bad?
Not necessarily. The issue is very often a software glitch that can be fixed with a system reset or a software update from the dealer. Always explore software fixes before replacing the expensive module.
Where is the Audio Control Module located on a 2018 Jaguar E-PACE?
The main processing unit, called the Infotainment Master Controller (IMC), is located behind the trim panel on the left side of the trunk/boot area, not behind the screen in the dashboard.
Can an independent mechanic replace and program this module?
An independent mechanic can physically swap the module, but programming requires specialized, expensive JLR-specific diagnostic tools (like Pathfinder) and a subscription to the manufacturer's service portal. Only well-equipped European auto specialists will have this capability; your average repair shop will not.
