Once this code gets set the TruLok Harness or even a Tuner if they try it, will not clear it. These steps must be followed step by step to clear the code.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003eFirst, make sure there is only one 4WD switch installed. The factory switch and our switch\u003cbr\u003ecannot both be connected at the same time, as this can damage the harness. If our\u003cbr\u003eharness was installed with the factory switch it could have damaged the harness as per the\u003cbr\u003einstructions.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003ePlease follow these steps in order. All the connections below are down at the differential\u003cbr\u003eonly, nothing under the dash.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e1. With the key off and the machine fully powered down, disconnect the TruLok\u003cbr\u003eharness from both the differential and the RZR.\u003cbr\u003e2. Plug the differential directly back into the RZR’s factory wiring.\u003cbr\u003e3. Start the unit and make sure the differential code clears. Sometimes you will need\u003cbr\u003eto put it in gear and move it slightly before it recognizes the connection and\u003cbr\u003eclears. There has also been times that some units require the factory switch to be\u003cbr\u003eplugged back in, but this is rare and okay as long as both connectors of the harness\u003cbr\u003edown by the differential are unplugged.\u003cbr\u003e4. Once the light clears, let the machine idle for 10–15 minutes with no differential\u003cbr\u003ecode showing. This part is important so the ECU can clear its memory.\u003cbr\u003e5. Shut it off and wait until everything completely powers down. (The interior lights and\u003cbr\u003eany whining or humming sound need to shut off before unplugging anything.)\u003cbr\u003e6. Back down at the differential, unplug the differential from the factory wiring. Plug the\u003cbr\u003eTruLok harness into the RZR first, then plug the differential into the TruLok\u003cbr\u003eharness. (If the factory switch was installed to clear the code make sure it is\u003cbr\u003eremoved)\u003cbr\u003e7. Start it back up and check whether the code stays clear.\u003c\/p\u003e\n\u003cp\u003ePlease let us know the outcome, good or bad, so I know everything is taken care of or if we\u003cbr\u003eneed to troubleshoot further. If it comes back, send me a picture of the code and the\u003cbr\u003econnections at the differential, and let me know whether 4WD works with the TruLok\u003cbr\u003einstalled.
