Circuit Question, Fuses. (on Immobiliser Press, Indicators Flash Problem)


Recommended Posts

I have an aftermarket immobiliser on my car. When you press the button the doors lock & the engine is immobilised. To let you know this has happened all indicators flash once for locking, twice when unlocking.

Now when I press the button, only the drivers side indicators flash when locking / unlocking. So only 3 out of 6 flash. (driver side, front / side /rear)

All indicators used to flash perfect, but since some recent electrical mod / changes, all indicators are not flashing when the immobiliser button is pressed. (but yes all left / right side indicator do work when using the indicator stalk)

Below is a history of recent events to help troubleshoot at which point my problem starts occurring.

1. front passenger side indicator stops working, fuse is still fine, & all indicators (except for passenger side front) flash when pressing immobiliser button.

2. Go to an auto electrician to get a no load flash unit installed (to fix up my indicator speed due to 5 watt globes at front). Installed & indicator speed back to normal.

3. At same time get auto electrician to look at the front passenger side indicator which is still not working. Accidentally (from a jiggle of a wire I guess) the front passenger side indicator is now working again.

4. On the drive home, turning left, the indicator fuse blows & I loose all indicators. I guess it was front a driving vibration / jiggle again. (make it home safely)

*from here below I think at some point the new problem has occurred 'immobiliser press, driver side indicators only flash*

5. Buy fuse, replace the blown. Test indicators, instantly blows the new fuse.

6. Disconnect the front passenger side indicator, install new fuse. All indicators work except the disconnected front passenger side.

7. Today, check positive & negative lines to front passenger side indicator, rewire & cover with electrical tape. Install new fuse. All indicators flashing fine. But, when on immobiliser press, still only the driver side is flashing.

Also, I had to replace the hazard fuse, this was blow when the indicator fuse was blow. Is it possible another fuse has been blow?

Thanks for the long read & help :pirate:

Cheers, :(

all new alarms have fuses for the indicator outputs, its to stop people shorting out the indicators like they do in gone in 60 seconds. so track down where your alarm is and it should have 2 fuses outside the unit.

i hope that makes sence

    • Yea mine does, I assume we all use the same sensor. I'm not sure whether it is exact down to the .1%, but it definitely does have decimal points involved.
    • Haha fair question. For two reasons. 1. Once I'm done migrating my water/methanol system over from pre-TB to direct port, I'll be hitting the dyno again. I also plan on trying Ignite E98 race fuel at the same time. I could not be bothered with emptying the tank every time, so anything between E70-E98 I'll be happy with. "Race" fuels are very expensive vs pump E85, so if I grow annoyed of paying, I may also just cross the border to fill a barrel and keep it in the garage.  2. Quebec is slowly increasing all pump fuels from E10 -> E15 by 2030. My daily fuel is 100RON + Water/Methanol and this will have an impact over the years. 
    • Maybe for when he's feeling rich and buys E85 drums
    • I have to ask, if all your fuel is the same, why did you buy and install a flex sensor?  I'm so confused, what do you use the flex sensor calibration tables for? 
    • Thanks everyone for the responses. Our fuel in Quebec is all E10 by law. We do not have any other options. I know in the US, E85 has a wide tolerance (~51-85%) and I had presumed E10 would also have a slight tolerance but to some peoples point... if it's regulated by law then more effort must be put in to keep it at 10%. I'm thinking I'm just going to remove my sensor, cap an end and fill it with different fuels I have in the shed for my lawn tractor, power toys, etc. They are all lower octane and from different vendors. I'm presuming if I still see no variance from 11% after that, then I can conclude the sensor is no bueno.    Your sensor reads down to .1%'s? I recall mine only reading 0-100%. I'll check in my ecu tonight in case I didn't scale it properly.
