Hey,

My 2011 Evo X SST (25K miles) suddenly wouldn't engage gear today while trying to pull away from traffic lights. Car was in Normal/Auto and had driven around 15 miles fine before. It appeared the car was in neutral as it was revving freely but not moving.

The dash was going nuts and was flashing up a few messages and rapidly bleeping and flashing CEL but didn't appear to be at a regular interval - it seemed a bit possessed. Messages coming up included "AFS Service Required", "Transmission Service Required", "Slow Down" also came up a while later.

The "Normal" mode (or "D1" - I can't remember now) and also the D on the stick were both flashing rapidly. Changing to Sport or Manual mode made no difference, nor did Reverse.

Recovery came around 90 mins later after car had been off. Same thing happened when attempted to start them. When got home around 2 hours after this first happened the dash has calmed down (no messages but CEL on constant) but I can now drive forward and back normally.

Any thoughts as to what happened? My code reader is broken but will try get hold of one over the weekend.

I managed to get a code reader last night but only pulling P1637.

Today I took to have alternator and battery checked which appear to be fine, hoping this was a one off I took the car on a hard drive but it quickly developed same fault again however it resolved itself after car was off for around 5 minutes.

I managed to get a brief video of the dash however this time only 1 message was really showing, however it still appears to be going a bit crazy, you can also see the AFS light flashing up briefly. Trying to select Sport mode, it would reset back to normal within a second. Also this time it packed in while at speed and could see the gears changing down but not engaging.

Hi,

Last service was last May/June (3rd year) by Mitsubishi. I'm not sure if SST fluids/filters were part of this.

That is a code that means you need a new electronic unit. (technically DTC P1637: EEPROM System (DTC storing malfunction))

If you car is under warranty, make them replace the mechatronic. If they say your warranty is void because whatever, tell them to fix it or you'll sue them. There is no modification whatsoever that could cause this code. Basically it means the electronics in the controller portion of the Mechatronic unit has eaten it. If it is intermittent now, it is only a matter of time until it is permanent.

I have seen NEW mechatronics fail this way after only a couple of months. The only way to fix it is to replace the electronic control module, which is not available separately from Mitsubishi. I sent a new mechatronic to Dodson for one of their customers, and it ate it 6 months later. Mitsubishi wouldn't stand behind that part sale, so I had to send them another electronic module to fix it.

Thanks for the feedback.

I'm hoping your wrong and just some strange electrical issue with the battery as the car appears to be out of warranty. I've had the code cleared and will continue driving around my local area and see if it does it again, if it does I'll take to dealer to look at.

On another forum someone also in the UK reported similar issues which went away after replacing battery which otherwise checked out fine when tested.

If the issue doesn't resolve, I do have serviceable electronic modules available. Just hit [email protected] up if you end up needing one. We'll hope not.

Cheers - will bear that in mind.

I fitted a new battery today and will go for a drive later this evening when the roads are quiet.

Similar thing as described above happened last night, I noticed the AFS lights (lights up road when turning left/right - not fitted in US market?) on the headlight assembly were flashing as well in time with dash lights. I haven't been able to find any wiring diagrams to work out what controls this. Normal headlights were fine though.

I'm going to save you time, money, and headaches. Call or Email Kozmic Motorsports, if you have not yet done so, and they will correct any issue you have with your SST.

I have been to numerous shops, many of which are highly recommended Evo shops, and not a single one of them could tune an MR or correct any SST issues, regardless of what they say.

The ugly truth is there are very few shops in the [STRIKE]country[/STRIKE] World that can correctly tune or fix advanced problems with the SST. Kozmic is one of those shops.
