Mitsubishi says it’s not covered by warranty, or quoted you for a replacement? If your dash says “FCM temporarily not available”, or you’re seeing an LDW, ACC or AHB error, speak to Auto Recal. We are the independent authority in Mitsubishi camera and lane departure warning systems. We test the existing unit, repair it where possible, or supply, fit, program and calibrate a compatible replacement as required.

Mitsubishi FCM service bulletins and recall
Newer Outlander FCM camera aiming issues
Mitsubishi Motors North America issued TSB-23-54-005 to correct camera aiming error codes in the 2022–2023 Outlander service manuals. Its TT283 guidance for 2022–2024 Outlander says Code 18 can occur when the camera cannot detect the target or the entered target distance differs substantially from the actual distance. We check the camera mount, windscreen, lighting and target setup during diagnosis. These North American references describe aiming issues. We verify the applicable procedure for the Australian vehicle by VIN.
Mitsubishi FCM recall and VIN list
Australian recall REC-001046 covers listed VINs for certain 2016–2019 Mitsubishi ASX, Eclipse and Outlander vehicles. The campaign addresses FCM software that can continue braking after the need has passed. Use the official VIN list to check inclusion and ask Mitsubishi about campaign completion. Mitsubishi dealers carry out recall rectification free of charge.

01Pre-Scan Assessment
Scan and assess the existing camera.
- 1.1 Prescan IDIdentify the fitted Mitsubishi camera and scan and record fault codes.
OUTPUTVehicle identification, scan results and work scope.
02Diagnostics
Test the existing camera.
- 2.1 DiagnosticsTest the old/existing camera using applicable Mitsubishi diagnostic procedures and fault information.
Auto Recal fault diagnosis: $125–$175. Fault diagnosis is $125 without a written report and includes a detailed CAN communication trace and fault isolation. We check the front camera, front radar and related wiring for harness and temperature-related faults.
Recalibration: quoted after assessment. We recalibrate the existing camera or radar where appropriate. If a replacement camera is needed, we can supply and install a compatible unit when it’s in stock.
Parts credit: $75 towards replacement parts sourced from Auto Recal.
Mitsubishi dealer pricing we’ve seen: $150–$250 for diagnosis ($198 before surcharge in one example) and $350–$500 for recalibration ($500 in one example).
Written ECU diagnostic report: Fault diagnosis with a written Job Service Record (JSR) is $175 total. Depending on the fault, the report can support your claim with Mitsubishi.
OUTPUTDiagnostic test results.
03Repair / Replace / Supply

- 3.1 Electrical RepairRepair wiring, harnesses and connectors; repair the camera where possible.
- 3.2 Module InstallationRemove and install a compatible Mitsubishi camera or radar as required.
- 3.4 Supply / FitSupply and fit a replacement matched to the VIN, original unit and approved part supersession.
Mitsubishi unit coverage and compatibility
On applicable models, the windscreen FCM/LDW/AHB camera supports Forward Collision Mitigation, Lane Departure Warning and Automatic High Beam. The separate front ACC/FCM radar supports Adaptive Cruise Control and FCM on applicable versions. Sensor arrangements and shared functions vary by generation, model, build and market; camera fitment alone does not establish ACC coverage.
Rear blind-spot radar is a separate system and cannot replace the front camera or radar. We check the VIN, full part number, fitted features and hardware/software compatibility before supply.
Replacement options
We’ve helped customers save hundreds of dollars on replacement units over the years.
In one Mitsubishi Outlander case, a dealer recommended replacement and calibration at $2,306.40. Auto Recal sourced and installed an available used camera, with an owner-confirmed customer charge of $830 for supply and installation. The amounts cover different stated scopes, so they are not presented as a like-for-like saving or evidence of completed calibration. Used-camera availability and compatibility depend on the exact unit.

Mitsubishi camera and radar questions
Does an FCM warning mean the camera needs replacing?
The warning alone does not identify the faulty component. We scan and test the existing unit and associated wiring before recommending repair or replacement.
Is diagnosis the same as calibration?
Diagnosis investigates the fault. Calibration sets the fitted camera or radar to the vehicle’s specified reference. A failed calibration can require further diagnosis; clearing fault codes is not a calibration result.
Will a used Mitsubishi camera fit my vehicle?
We check the VIN, original unit number, fitted features and compatible replacement references. A similar appearance or matching connector does not establish fitment. Send a clear photograph of the unit label with your enquiry.
Can you help with Outlander, ASX, Eclipse Cross or Triton?
Send the model, build year, VIN and dashboard warning. The camera, radar and supported functions vary by vehicle; we confirm the fitted unit and service scope before quoting.
