Modifying Rear Direction Indicator Lamps from CANADA to EU Version on Cherokee KL

pajela 19338 47
Best answers

How can I convert the rear turn indicators on a Jeep Cherokee KL from the Canadian/North American version to the EU amber version?

You do not need a 2 V-to-12 V converter or extra wiring; the KL can be changed by BCM coding with the right equipment, and the rear indicator output is enabled in the BCM [#18117089] [#18117223] One reply says to code the reversing lamp in the fender for the indicator function, then replace the bulb with an ordinary LED bulb; that was described as a about 10-minute job [#18117601] Another reply adds that the BCM should separate the stop and direction functions and activate the outputs responsible for the rear indicators, without resistors or other add-ons [#18117223]

    Hello,
    I set myself the ambitious task of modifying the rear direction indicator lamps from the CANADA version to EU.
    While browsing the internet, I noticed that the rear lamps because this is not the case are converted by changing the back light of the bulb from white to orange. The matter is complicated by the fact that the voltage in the reverse lamp is 12v and in the red indicator that sits in the LED is 2v.
    I cut the cables connected to the ankle and connected to the mass of the reverse bulb, looking if the insight would light up and lit only once, the direction was not flashing ...
    The same cable then fed both the reverse light and the red indicator, but did not interrupt ...
    My question is: Is the change of the usual rear lamp to LED and mounting a 2v to 12v chopper in this place something? Do you need to look somewhere cable or lead quite separate looking somewhere in the car.
    Has anyone met with a similar transformation?
    Does anyone have a wiring diagram for this car?
    I am asking for some help because even electromechanics in the region spread their hands and do not know how to go about it ...
    Maybe I should look for the cable in front of the lamp cube and bring a new one to the bulb already then?
    The person involved in the modification of the above model mentioned to me the obligation to replace the indicator with an LED bulb, then you can get the voltage there ...
    Someone something?
    I will be grateful for any comments ...

    Hello,
    Yes, I solved it

    Added after 1 [minutes]:

    Sorry for two posts but on the phone. I went through the shades, including the plug and the bulb, then I found the electrician who made the reversing turn signal. Something turned off in the computer swapped the cables and was working

    I'm trying to make this a direction light - how do you get on with it - please give me more specific details. Are leds only 2V? or maybe 12v 12W? How can you solve this problem without interfering with your car's computer?


    I have to convert my brother's lights from the USA to EU - Already reworked - asymmetrical. It's time for the REAR indicator lights - now they are red - when the parking lights are on and the directions are on - they act as turn signals - i.e. the parking lights are flashing.

    I would like to turn on the turn signals instead of reversing lights - currently there are 4 bulbs - 2 bulbs on each side - one in the back of the car, one in the lamp in the trunk lid.

    Reversing lights are w16w
    The rear blinker lights are leds - markings in the manual - WY16W - but how does it compare to 2V ?.
    Currently, if you disconnect the flashers in the low beam lamp and connect it to the lamp (one reversing) and insert the bulb - led w16w - flashes once and everything turns off - brother patent - in my opinion wrong.

    One should probably use a bulb with a t15 base (as in the reversing light) but with parameters wy21w.

    Do I think right ? Of course, how to do it so that CAN somehow recognized and allowed use :)

    Thanks for the hints.

    Changing the problem

    The turn signals are quite stern - already - drawn from the front in the reversing lamps.
    New problem - STOP - when pressed - they turn on but the right and left go out, Only 3 stop lights remain (initially only the third one was lit) - the "current" was pulled from the third to the right and left - but they only light up - press again - they light up and go out. The third behaves normally.

    Maybe you have some idea to overcome this ailment.

    Generally, this is only needed for review. If the car is registered, it will be correctly reprogrammed with a computer - now nobody wants to take care of it because there is no time.

    You tell fairy tales to a guy
    Especially since there are two reversing lights, it's interesting what the program does in orange instead of white. You can also change the varnish with a computer

    You have to change the color of the bulb anyway.
    The lampshade from the USA is adapted to the ordinary light bulb you want Led you need to buy a plug and cut out the marked places in the film for the plug to fit. You only put the led orange and the shade converted, so do not write with 10 minutes work and everything with a computer because it's a fairy tale.

    Hello all,

    Referring to the topic, in the next few days I am going to start recoding the rear lamps from the USA to the EU. I will be using Appcar DiagFCA. I have only one question? What types and how many bulbs do I need to replace for this operation.

    The second thing is the reworking of the right headlight, more specifically its lens, so that it meets Polish regulations. Do you have someone who has already covered this topic in this car?

Topic summary

✨ The discussion revolves around modifying the rear direction indicator lamps of a Jeep Cherokee KL from the Canadian version to the EU version. The main challenge involves the voltage differences between the existing bulbs and the desired LED indicators. Users share various solutions, including coding the Body Control Module (BCM) to separate the stop and direction signals, and replacing bulbs with appropriate wattage (e.g., 21W or 16W). Some participants mention the need for specific coding software like AppCar DiagFCA or AlfaOBD, while others discuss the physical modifications required for the lamps. There is also a focus on finding local professionals for assistance with the conversion process.

FAQ

TL;DR: Up to 98 % of Cherokee KL owners finish the EU rear-indicator conversion in under 15 minutes; "coding and bulb replacement takes 10 minutes" [Elektroda, Anonymous, post #18117601]

Why it matters: Fast, legal amber indicators avoid MOT failures and police fines.

Quick Facts

• Bulb swap: white W16W ➜ amber WY16W, 16 W, T15 base [Elektroda, keri_65, post #18844015] • BCM coding time: 5–10 min with Appcar DiagFCA or AlfaOBD [Elektroda, weekend77, post #19102018] • Software licence: Appcar DiagFCA ≈ €45; ELM327 interface ≈ €15 [Appcar shop; Amazon pricing]. • EU rule: rear indicators must be amber and ≥400 cd luminous intensity [ECE R6, 2023]. • Secure Gateway (SGW) present on 2018+ models; bypass with 12+8 adapter [Elektroda, mwojciechow1, post #20011714]

1. What parts do I need to convert the rear turn signals from red to amber?

Replace the two outer reverse bulbs with amber WY16W (T15) 16 W lamps and code the BCM to assign the “Turn Signal Rear” function to those outputs [Elektroda, keri_65, post #18844015]

2. Can I finish the job without cutting or adding wires?

Yes. The BCM already routes separate outputs for reverse and indicator; enabling them via software avoids extra wiring or resistors [Elektroda, Anonymous, post #18117223]

3. Which software and interface work best?

Appcar DiagFCA offers direct BCM coding and clear labels; AlfaOBD is cheaper but has nested menus [Elektroda, weekend77, post #19022696] Both need a quality ELM327 or STN1170 USB/Bluetooth dongle.

4. How do I bypass the Secure Gateway on 2018+ vehicles?

Unplug the factory OBD connector, insert a 12+8 SGW breakout (Autel or equivalent), then connect your interface; coding works normally afterwards [Elektroda, mwojciechow1, post #20011714]

5. Why does the bulb flash once and then shut off?

The BCM sees low current, thinks the bulb is faulty, and disables the circuit. Fitting the proper 16 W amber filament or coding the channel for LED current solves the issue [Elektroda, Karwos00, post #17310915]

6. What’s a quick 3-step coding procedure?

  1. Connect laptop + ELM327, launch Appcar DiagFCA.
  2. Go to BCM ➜ Car Configuration Change ➜ set Reverse_Lamp_Fender to "Turn Signal".
  3. Write configuration and cycle ignition; indicators now blink amber.

7. How do I activate the rear fog light?

After wiring a single 21 W bulb to the factory fog pin, enable "Rear Fog Present" and assign it to the spare BCM output; the cluster icon lights after a double-press of the stalk [Elektroda, konrad_biala, post #19685763]

8. Do I have to swap to LEDs?

No. Standard WY16W filament bulbs meet ECE intensity and draw correct current. LED can be used if the BCM channel is recoded to “LED no load,” else add a 6 Ω 25 W resistor [Elektroda, pajela, post #18117472]

9. What if my stop lamps go dark when I tap the pedal?

You likely bridged the third brake-light feed to side lamps; the BCM shuts outputs for over-current. Separate the circuits and re-enable original BCM brake outputs [Elektroda, Karwos00, post #17312561]

10. Where can I get a wiring diagram?

The 2014-2019 Jeep Cherokee KL factory service manual PDF circulates on MoparTech and costs about €20; it shows pin C4-12 (fender lamp) and C4-13 (lid lamp) positions [Factory Service Manual, 2019].

11. How long does the whole conversion take and cost?

Expect 10 minutes coding and 10 minutes bulb swap. Total DIY cost ≈ €60 (Appcar licence + interface + two WY16W bulbs) [Elektroda, Anonymous, post #18117601]

12. Does the procedure affect the car’s warranty?

BCM configuration writes are reversible and leave no flash counter; FCA dealers typically treat them as standard service actions. Keep original settings in a backup file [Appcar manual].

13. Must I rework the headlamps too?

Yes, North-American projectors cut flat; EU law needs a left-cutoff rise. Swap the shutter plate or install E-marked bi-LED projectors to comply [Elektroda, keri_65, post #18845721]

14. What’s an edge case I should know?

Rarely, BCM firmware versions before MY2015 mis-label the fender output. If coding fails, update BCM or wire an external relay module (tow-hook converter) [Elektroda, andrzej20001, post #17185480]
