Hi everyone. I have a 2005 Panda Maxi 1.2 dualogic, a Japanese domestic market model I have imported. I keep getting ESP, Hill Holder and the Oil pressure sender errors all 3 at the same time. Sometimes the car starts and the 3 error lights and messages are gone and do not reappear.
I have multiecuscan and connected the car today and got the following messages which do not help me much in trying to track down the cause of the faults:"P0856 VDC message (from CAN)"
"B1022 Serial line W"
"C1117 Steering angle sensor"


Any help in telling me what these mean would be greatly appreciated. I am reasonably competent mechanically, most recent engine job was cracked cylinder liner replacement on a truck engine in the tropics with basic tools, job a complete success, but electrics are not my speciality....
Car has a near new 4 month old battery, is clean under the bonnet and all earths that I can see have been apart and reassembled. They all were clean and bright to start with.


A Japanese Panda Maxi has "all the fruit" as they say... alloys, skydome roof, spot lights, ESP and Hill holder, roof rails etc. A nice little car.

Hi,
a poor battery would've been #1 choice..,
but that should be fine,
what voltage is the MES seeing..??

pretty sure the codes are CANBUS related,
have you tried a Proxy align?,

P0856 is often an issue with the Electronic Brake Control Module or harness. (ESP/Traction control, VDC is vehicle dynamics control)

B1022 is a coms failure of the OCS (airbags/pretensioners)

C1117, as you've discovered is the steerings torque sensor.

The only thing I can think of that all three have in common is a need for speed signal from somewhere.
ESP only works at a certain speed.
Same for airbags.
And the steering needs a speed signal to determine how much assistance is needed.

Hi Varesecrazy and Goudrons, thanks for taking the time to reply.
I have had the car on multiecuscan again today, it reads 13.8 volts with engine running so that seems fine. Also MES says no proxy alignment is necessary.
Only error code today was C1117 steering torque sensor, but all dash lights off for now..... Thanks for the lead that it could be speed signal related but why would that explain the oil pressure sender failure light always appearing at the same time?
I have posted a picture of a fried wire I discovered in the big bundle that runs across the scuttle in the wiper arm panel. All the cloth tape was gone and insulation from this wire too.... I cut it and covered it in shrink tube before re soldering it. Ah! the joys of second hand cars!

no problem,
:idea:any idea if these are all fed via one EARTH / Ground.., or powered through 1 fuse or relay..??,

Hi again Varesecrazy, thanks for the hint the 3 failure lights could be linked on some circuit somehow.
All 3 lights on again last couple of days, can anyone tell me why the Hill holder, ESP and Oil pressure sender failure lights are all on together or on (rare) days all off as well? They do not seem to be related to each other except on my dashboard!


Thanks, Bergi.

sorry - no ideas on the actual wiring..

Thanks again Varesecrazy, lights have been all on and all off during various drives over last couple of days. I would like to think it's some poor connection somewhere but no idea where to look..... Will persevere for now and see if it gets worse or goes away.
Thanks again Bergi.

OK more on this... I had a long 600 km mountain drive yesterday and found that with the speed limit warning set to "on" when the pre set speed is exceeded the orange warning triangle with the exclamation mark illuminates as well as the warning buzzer and the message to slow down in the central display. This is news to me as previously I thought the orange triangle was exclusively for the oil pressure sender but obviously not.....
So, in light of the first post perhaps it is all related to speed sensors after all.
On another note, I "discovered" that you can change the brightness of the instrument lights in the display menu only when the lights are on.... its the last setting to change in the menu. Interesting, I did not know that setting existed....
