CX-5 FORScan Tweaks (KE / KF, 2016–2020)
This page covers only what’s specific to the CX-5. The adapter, the AS-Built backup, the checksum recalculation, and the bit-level recipes that are common across SkyActiv cars live on the platform pages — see the FORScan overview and the complete mod list. Below is the model delta: which years and trims apply, and where the CX-5 differs from the MX-5 and Mazda3.
Years and platform
Section titled “Years and platform”Gen 6 MZD Connect CX-5 splits into two body codes:
- KE — 2016 facelift only. The 2013-2015 KE uses a TomTom-based infotainment head unit, not MZD Connect, and is out of scope here. 2016 is the year the CX-5 moved to the touchscreen CMU.
- KF — 2017-2020. The commonly documented platform for FORScan work. Byte positions in the mod list are validated against KF; 2016 KE owners should diff against their own AS-Built backup before assuming a KF recipe applies.
2021-and-later CX-5 is Gen 7. Different head unit, different module architecture — FORScan recipes from this site do not carry over. See Gen 6 vs Gen 7.
CX-5-specific changes
Section titled “CX-5-specific changes”Most of these use the same RBCM/FBCM/SSU addresses as the rest of the platform; the complete mod list has the exact bytes. What’s noted here is where the CX-5 behaves differently.
i-Stop default OFF
Section titled “i-Stop default OFF”The single most-requested CX-5 change. The SSU bit that controls i-Stop startup state lets you default it to OFF on every engine start while keeping the dash button to enable it manually. The CX-5’s i-Stop cycles aggressively in stop-and-go traffic, which is why this comes up more on the CX-5 than on lighter platform cars.
2019+ CX-5 with the 2.5L turbo runs a different i-Stop implementation than the naturally aspirated engine. The default-OFF bit works on both; reactivation behavior differs slightly.
Markets that brand the feature “Auto Start-Stop” rather than “i-Stop” use the same SSU address and bit.
Auto Hold default ON
Section titled “Auto Hold default ON”2017+ KF with the electronic parking brake can default Auto Hold to ON at each start instead of resetting to OFF. The button still toggles it manually. NA CX-5 trims with a foot or pull-handle parking brake don’t have the EPB module and can’t do this — confirm you have the electronic brake first.
DRL configuration
Section titled “DRL configuration”The CX-5 has more DRL options than the MX-5 because more trims carry LED headlights and signature lighting. 2017+ Touring and above with LED headlights ship a different default DRL source than halogen trims, so read your current value before changing it. Options range from parking-lights-only to a turn-signal-lamp signature look on applicable trims.
Auto-fold mirrors
Section titled “Auto-fold mirrors”Only works if your CX-5 actually has power-folding mirror hardware. Base and Touring trims typically don’t; Grand Touring and Signature may, depending on market. Verify the manual fold button on the driver’s door works before attempting the change — no button means no hardware, and the write will do nothing.
ESS, Find My Car, headlight-off timer
Section titled “ESS, Find My Car, headlight-off timer”Emergency Stop Signal (rapid hazard flash under hard braking) is supported on all CX-5 trims and needs no added hardware. Find My Car (horn + hazards on double-lock) and the post-shutdown headlight timer behave the same as the rest of the platform. Recipes are in the mod list.
ADAS: check the hardware first
Section titled “ADAS: check the hardware first”Unlike the ND MX-5, many CX-5 trims ship real ADAS hardware, so the IC display options for these features are safe to enable if the sensors are present:
| Feature | Available on | Hardware |
|---|---|---|
| BSM (Blind Spot Monitoring) | Touring+ | Rear radar sensors |
| SCBS (Smart City Brake) | Grand Touring+ | Near-IR laser (early KF) or forward camera (Advanced SCBS) |
| LDWS (Lane Departure Warning) | Grand Touring+ | Forward-sensing camera |
| MRCC (Radar Cruise) | Grand Touring+ | Front radar |
| HBC (High Beam Control) | Grand Touring+ | Forward-sensing camera |
If your trim was built with the feature, the sensor is there and the display option is fine to turn on. If it wasn’t, enabling the display option only surfaces a menu for hardware you don’t have. The KF carries more ADAS hardware across the range than the 2016 KE, where forward-camera features were rare.
