Hi,

I've scanned my car and it shows a few recurring intermittent faults (I cleared all faults Saturday and some have come back)

These relate to a couple of things, one of which is the rear camera module. The cameras do work so it is only an intermittent fault.
I am hoping this is simply a poor connection but first I need to identify where the module is, what it looks like, and where the wiring is routed

Are there any 2010 on circuit diagrams / workshop manuals, or suggestions of what to check first ?
I have had a wander through the wiki and the various manuals, but they don't specifically cover the later cars.

The surround camera module is underneath the front passenger seat.

Thanks Graeme that's just what I was after.

The diagram indicates the module has a permanent live which surprises me.
Or does one of the modules isolate the voltage feed when ignition is off ?

Further investigation shows the cameras don't come up after ignition on for a few minutes, then the fault clears.
Next to investigate the supply.

The previous owner had put a new battery on so I wonder if he disturbed something.

It will activate on specific canbus messages.

Thanks.

Having cleared the fault codes again last night the cameras didn't wake up this morning
I hope this is power related, or a poor connection.

What else is under the passenger seat that is on the can bus so I can confirm the bus wiring is OK ?

Is the fuse on that diagram behind the glove box or somewhere else ?

Where is the earth point, under the seat ?

I am guessing this is probably a seat out job, right ?

Didn't even manage a week before the first investigation is necessary

Thanks for your replies.

The letter P after the fuse number indicates the Passenger compartment fuse panel. E=engine, R=rear.

If there was a canbus fault then there would be various faults from other modules indicating loss of contact with the camera module. Are there any camera module faults?

The total earth wire length to the earth point as shown on the schematic is over 6 metres so won't be under the seat.

How good is the battery? The camera module are one of the first to be shut down if voltage can't be maintained.

I wonder if when the new battery was fitted if the battery monitor was reset. Also, check the alternator o/p to see if it's charging properly.

OK, thanks.

This was not the guys daily driver so the battery died.
It has a yuasa battery which is a few months old now.
When I cleared the codes the first time there were various historic codes to do with battery voltage.
I took a note of what it reported before clearing. They were as follows (quite a list, but no idea when they were last cleared):
Intermittent
U01 32-00 lost communication with ride level control module
U0415-81 invalid data received from ABS control module
U0128-00 lost communication with parking brake contol module
U0264-00 lost communication with the rear camera module
U0140-00 lost communication with body control module
U0156-00 lost communication with information centre A
B1 2C0-31 left mirror camera
B1109-15 passengers door central locking motor
B1 A08-13 speaker 8 circuit
U3003-16 battery voltage
U3003-17 battery voltage
U1 A03-55 vehicle configuration parameter

Historic
B1 2BD-31 Rear Camera
U3003-62 Battery voltage
B1D50-93 DVD unit

I forgot to make a note of which areas reported what.

What I get now is as follows:

from IPC - instrument cluster control module:
U0128-00 lost communication with parking brake contol module (Intermittent)
U0264-00 lost communication with the rear camera module (permanent)

from ACM - Audio front control module:
U0264-00 lost communication with the rear camera module (permanent)

From PDM - passengers door module:
B1109-15 passengers door central locking motor (intermittent)

From RDCSM - rear climate seat module:
U0140-00 lost communication with body control module (intermittent)

Rear climate, handbrake and central locking all work fine.
If those modules are all under the seat that would be quite a coincidence...

Does it have surround cameras or only a rear camera? If only a rear camera then no surround camera module will be fitted.

It seems to me that there is an intermittent cab-bus fault and if the rear camera is the only component that isn't working then the fault may be with the wiring to the rear camera, either directly interrupting canbus operation if rear-only camera or causing the surround camera module to temporarily interrupt the canbus until it stops trying to communicate with the rear camera. If surround cameras are fitted then unplug the rear camera from the module under the seat to see if the other faults re-occur on next start-up.

Here is the schematic for a rear camera only system. It is powered from the rear fuse panel.

edit: As the rear-only camera system does not use the canbus, the surround camera module must be showing a rear camera fault as though it is directly connected to the canbus. Unplug the rear camera at the under-seat module.

Just a thought.......when the battery was replaced, did the owner perform the battery reset procedure (start engine, turn steering all the way left, hold for a couple seconds, then all the way right and hold for a couple seconds)?

Hi guys.

It has the full set of surround cameras.
They worked on the drive home today after the usual few minutes.

I cleared all the fault codes again tonight and the camera module one came back straight away.

I figured out how to access the camera module so will give it a try when I get chance.

I have no idea if he did a reset procedure when he swapped the battery, at least he didn't tell me. Probably not as I doubt he knew to do that.
Is there anything else that is meant to be done ?
Is it worth reconnecting and trying now ?

Just trying to eliminate the obvious first.

I suspect many of the ecu''s report or hold on to errors, despite there being no "real" problems. So if the service (like rear camera) works, then ignore that error and focus on those causing real problems.

My car reports issues with one headlight and one speaker, but both work fine despite having the errors erased regularly.

Stan has written how to disconnect/ reconnect battery, it is in the Wiki, may be worth a try.

Thanks guys.

I will go look for the dis/connect notes.

The cameras worked from the get go today, so it's definitely an intermittent one, and hopefully just a connection. I plan to have a play about at the weekend so will find out then.
