2003 r1 code 30

[Sam Boughton]

Hi guys, so I've got a 2003 r1 that keeps showing code 30. I checked the manual, lean angle sensor, ordered a new sensor and it was fine for 1 ride tried to start the bike Sunday and it gave a code 30 again, wouldn't let me clear it from the diag mode either, when I check d08 it's showing 4.0 so is definitely put of the parameters, if I wiggle the sensor it doesn't fluctuate on the dash, any help would be so appreciated not really sure what to do next.

You haven't bought a duff lean angle sensor have you?

 I rode the bike Saturday with the new sensor and everything was perfect, it only happens when I try to turn the bike on and Saturday it didn't happen once. Started the bike maybe 5 times on the Saturday. I have opened the sensor up and checked the pendulum and it all seems OK no corrosion or anything. Really got me stumped on this one. 

[Stu]

I suppose the next thing to be checking is the wiring to make sure there is no corrosion at any of the connectors etc

Would it just be the wiring to the sensor or all connections?.. Thanks mate!

[Stu]

I would check everything as it could be as simple as a bad earth

Thanks again mate! This weekend il go over all the connections with cleaner and give her another go

So a little update, I charged the battery as it seemed to of drained while attempting to start the bike on Sunday. Connected it back up turned the key and it turned straight on! Went into diag mode and checked d08 it's reading 0.6 which is within the parameters checked the error codes and it said 1,, code 30, it let me clear it straight away though! .. Started the bike and checked the battery with a meter and it is charging so I'm still not sure what the issue is I thought maybe the low power from the battery caused the sensor to freak out but why would the battery be low on power if its being charged by the bike I'm honestly so stuck

Oh and the battery is new, maybe 2months old it's an AGM battery

Sound like youve got a little vampire or shorts possibly. Does the bike have a immobiliser or alarm or tracker?

 

if the battery is good enough to start a bike its fine for the system, so a sensor isnt gonna be bothered by it.

 

is the sensor secured well enough? bolted in and in the correct way? The plastic housing  if loose can fool it, Id be checking the relays too, if they are sticking or tripping that can make it think its sensor has gone off.

Actually not true! 

 

A weak battery can cause all sorts of issues with sensors and electronics 

 

When you hit the starter if the voltage drops too low at some sensors and electronic components it can throw an error!  ABS pumps can be a nightmare and I have known a weak battery destroy and ABS pump or two 

[Stu]

@Sam Boughton You have cleared the error codes between testing haven't you?

It had a datatool s3 system but it's been bypassed because it was killing the battery, that was by the previous owner. The bike was perfect for about 6months. 

Yeah the sensor is in the correct place, the bike was actually on a Paddock stand when the bike showed code 30 on the Sunday. Tomorrow I'm going to check connectors and stuff see if there's any corrosion.

When I was trying to start the bike the dash and lights would go off so I knew that the battery was dying but the code 30 was happening before the battery started dying. After I charged the battery I put it back in the bike and the bike is charging so I'm not sure why the battery was dying

Yes yesterday when I put the battery in I went into the diag mode and cleared the code then started her up. Went out for a short ride turning the bike off once while I was out and it started fine on the turn of the key no code 30

Sounds like a strange one! All you can do is keep an eye on it and hope it's fixed although it doesn't do much for confidence

Old batteries can do that 

 

Do you keep it on charge? And if not how often do you ride?

It's a new battery, I got it about 2months ago that's why I was a bit confused why it was almost dead especially when I checked and it is charging I try to ride every weekend both days but sometimes just 1 day a week I get out for a few hours. I don't keep it on charge but I might start .. It is a really strange one and I agree it kills my confidence to go far from home

Sorry! I thought you said you replaced it because the old one was not holding charge! 

 

Anyway any accessories fitted like usb chargers or alarm and immobiliser?

It does have a datatool s3 but it's been bypassed because it was constantly draining the power done by the previous owner, looked at removing it completely but it's wired in so professionally into the immobiliser and everything, no other accessories to the bike

It could still be this draining it unless its been removed from the power?

So what we did was bridged between 2 different wires on the alarm, it's totally disconnected from the alarm unit itself .. Just tried the bike now and code 30 again, hasn't moved off the paddock stand and it won't let me clear the code so I'm just about to start checking connectors and relays thankfully this time I wasn't fulled geared up ready to go

Out of curiosity, check the battery and see if it's lost charge, which as Stu says, could potentially cause errors.

 

If there's nothing draining the power, it could be the reg/rec not charging the battery whilst you ride, so it slowly drains and throws up error codes as it does so?

 

I could also be way off the mark, as I'm no mechanic, but may be worth a look if you've been over everything else

I just checked the battery to see if it's draining, it's reading 12.7.. On Thursday when the bike was running I checked and while running it was ready high 13s maybe low 14s I don't rememeber exactly, I'm really stumped what's going on, I just disconnected the battery to let the bike drain out as that seems to help

You need to check what's been drawn through from battery with the live off and using your meter as the bridge if you follow
