Stratus Security Alarm Dead: DIY Reset vs Shop Repair

Had similar automotive alarm problems with a 1998 Chrysler Sebring. The security breach symptoms matched exactly, complete system failure and no response from the alarm controls. After diagnostic testing, it turned out the siren module wiring issue was causing the fault codes. The main harness connector behind the front bumper had corroded, breaking the circuit. This is a known weak point in these models where water can seep in. The repair required removing the front bumper cover to access the alarm siren assembly. The wiring harness needed replacement along with the corroded plug connection. This resolved both the vehicle security system failures and error codes. While not a complex fix for an experienced tech, accessing the components makes it a time-consuming job. The security system integration means proper diagnostic equipment is needed to disarm and reset the alarm after repairs. This type of failure is common in early 2000s Chrysler models once they age. The repair is worth doing properly to prevent recurring issues with the factory security system. The job requires specialized tools and knowledge of the security protocols. Best handled by a shop familiar with Chrysler alarm systems rather than attempting DIY repairs that could cause additional system conflicts.

Thanks for explaining that signal problem fix on your Sebring. I ended up having nearly the identical issue on my 2001 Stratus last month. The alarm disarm sequence stopped working completely and left me stranded a few times. I got it repaired at a shop but wondering what you paid for the full harness replacement and alarm reset job? Mine felt expensive but maybe thats normal for this type of vehicle security repair. Also curious if youve had any other problems pop up since getting it fixed? The technician mentioned these early 2000s models often need the whole wiring assembly replaced once corrosion sets in. Just want to know what to expect down the road with this system.

The repair bill came to 95€ for fixing the siren communication fault on my Sebring. The main cost was labor since they needed to replace a corroded plug connection rather than the entire wiring harness. The automotive alarm has worked flawlessly since that repair last year. The fault detection system would occasionally trigger before the fix, but replacing that damaged connector completely resolved the signal problem. The shop mentioned these alarm system issues rarely come back once the corroded components are properly replaced. Your case sounds nearly identical with the alarm disarm troubles. While 2000s Chryslers can develop other electrical quirks, the security system typically stays reliable after addressing the root cause of the wiring fault. Just keep an eye out for any water intrusion near the front bumper area since that tends to accelerate connector corrosion.

I finally took my Stratus to get checked out after seeing these responses. The mechanic confirmed it was exactly the wiring issue described, corroded connections near the front bumper causing the alarm controller to fail. The repair took about 3 hours total. They had to pull the bumper cover to access the fault detection module and replace the damaged wiring harness. Including parts and labor, the total came to 280€. More than I hoped but less than I feared. The automotive alarm system now works perfectly. No more unusual security triggers or failed disarm attempts. The mechanic showed me the old corroded parts and explained how water damage had slowly eaten through the connections. He also sealed everything better to prevent future moisture issues. Worth every cent to have it properly fixed instead of trying cheaper shortcuts. The alarm reset process needed their specialized diagnostic equipment anyway. At least now I know what caused the problem and that its properly sorted.
