Hi,

lol, starting to run out of ideas on this 1.

I found a damaged Hill Hold sensor, by the airbag module.. well I say damaged the plastic casing was damaged.

Changed it.. and thought that will be whats causing the hill hold failure error if dampness is getting in there or has got in it at some point.. didnt look too clever inside. because normally its a sealed unit with a rubber type sealant around the top.

so after changing it, thought great that hopefully has cured it.

then tonight it flashed up hill hold failure, esp failure again.

battery isnt even 2 years old yet so can probably rule out that.

going to try brake pedal switch next, but it seems to be working fine.. lights arent sticking on and they come on and go off fine.

tried to see if theres any way of adjusting it? but couldnt see any visible way of adjusting it. So I guess new switch replacement is next thing to try.

The brake light switch is adjustable for reach.

Have you 'done an earth' job on it?

Cheers

to adjust the brake light switch, not sure if accurate but seems to be automatically adjusting on a ratchet.. so would require removing, then resetting and it should re-adjust itself?

only earth ive done so far is the 1 underneath the ABS module, and 1 on the engine ECU... I know theres the 1 on the engine... but it shouldnt be that 1.

not entirely sure where the rest of the earths are and ive had the whole interior out the car pretty much.

Not 100% sure if this is a help but i'm pretty sure theres one in the boot under the carpet at the left hand side of the boot latch mechanism. I used this earth for my speaker AMP.

It should go in to the mounting hole and then a 90 degree turn locks it off.

hi, will try removing it tomorrow and resetting the adjuster on it.

regarding the earths,

Im guessing the black rectangular shaped boxes which bolt to the chassis and have several black wires going into them are the earth points.

1 under the steering column left side, which is bolted to the re-inforcer next to the heater box

1 in the boot under the carpet, left side

1 under the bonnet, right chassis leg around the area underneath the battery box

1 single earth wire underneath the ABS module

1 on the engine ECU

1 from battery that goes to eigther gearbox or chassis, cant remember now lol

1 on the engine rear, bottom just above the sump.

1 for the airbag module, by the airbag module.

those are the only ones ive identified so far

the 1s inside the car all look clean and fine, checked the 1 in the boot that also looks ok, 1 under the ABS module.. I cleaned that one up when I fitted the new engine bay wiring loom.

Steering position calibration and torque sensor calibration could throw up the random steering error and ESP error.. but neither of those would explain the hill hold failure.

really only components involved are the hill hold sensor which is fine now.. replaced with a 2nd hand 1 in good condition.. and brake pedal switch that appears to be working ok.

Most Hill holder faults are down to an incorrectly adjusted clutch pedal switch.

Hi, clutch or brake?

only heard brake, but will check clutch as well.

doesnt explain the ESP failure error though.
was a new ABS module, and error was coming up as soon as a mile down the road after having a proxi alignment done in the dealer.

so shouldnt be module as that was new, havent experienced ABS failure so can rule out the sensors.. which doesnt leave a lot for it to be at fault lol

Clutch pedal switch. On the clutch pedal. Very similar to the brake pedal switch. Usually caused by people accidently flicking the pedal up and moving the adjustment of the switch.

What was the ABS problem? Was it the correct ABS ECU fitted?

Hi, from what i can gather they are auto adjusting on a kind of ratchet.. but i will remove them, reset them and let them auto adjust again.. see if that fixes it.

ABS problem was, the module was completely dead lol, amonst a whole load of other problems, like bad wiring.

wiring looms in the engine bay and dash was replaced with brand new, only 1 not changed was the rear/floor loom but that seemed in ok condition anyway as a lot of it is covered up by the carpet... doesnt do a lot, mainly just the roof airbags, seat airbags, door locks and windows, rear lights... so I wouldnt of thought that would be the cause of the errors.

only reason engine bay loom was changed was because all the headlamp wires had all been cut about and badly joined, probably damaged in a previous accident, and dash loom probably damaged at the same time, city button didnt even work at all, nor did the ASR button, and there was all sorts of airbag errors because of the passenger airbag wiring and deactivation switch... changed the loom then the city button started working, and ASR button lit up.. but still didnt work so changed the ABS module and that got that working and the speedo, after the dealer cleared all the error codes, and there wasnt any permanant errors returning then did a proxi alignment. So whatever is causing these errors really is intermittent, I thought the hill holder failure was because of the sensor by the airbag module.. top was all cracked and damaged on it, changed that and thats now good, but errors are still popping up

it is the correct module, only 2 available, standard 1 without ESP, ASR, VDC.. and 1 with ESP, ASR, VDC.

so the ESP, ASR, VDC one was fitted which is the correct one because the car has the ASR button.

No need to remove it to adjust it. Just press the pedal down, and using some needle-nose pliers, grip the end of the plunger on the switch and pull down a few clicks. Then let the pedal up and it will ratchet up to the correct place. Clutch switch issues can affect ESP too.

How do you know someone hasn't possibly fitted the wrong centre console with an ASR button in the past? Did you check the spec against Eper or SIGI?

How old is the car anyway? Hill holder was introduced late into the Punto's production, and I'm sure I remember ESP being a completely seperate option to ASR (as in some had ASR but no ESP), but it's been a while.

hi, thanks for the feedback, will try that after christmas.

wrong centre console has not been fitted, because the old wiring loom had a connector connected to the ASR button, and so did the brand new loom ordered from fiat dealer... also it is a 1.4 sporting MK2B.

and theres only 2 ABS modules available, 1 with just ABS, and 1 with ABS, ESP, ASR etc so couldnt really go wrong with it.

Also, has the ESP Yaw sensor under the drivers seat which is plugged into the wiring loom, and the Hill holder sensor which is plugged into the wiring loom by the Airbag module underneath the heaterbox.

so with all the wiring, and sensors its definitely supposed to have ESP, ASR, and Hill Hold.. think those were all standard on the 1.4 sportings and HGTs

All ESP ABS modules support ASR because its the same module, so if it was an option must of only been the missing ESP wiring and Yaw sensor under drivers seat, but all the wiring is there and sensors.

When you press the ASR button, also flashes up on the instrument cluster, ASR On, ASR Off.
and havent seen ASR failure pop up, just Hill Hold and ESP failure.
