Also, good to know ground points.

Thanks. Definitely more than what came with the car, but they don't clearly identify the Turn Signal Relays. Are they the T.15 R Relays?

 

[jbanks15]

Maybe there is no turn signal relay. Maybe it is controlled by the Sams. Just thinking out loud. Seanhump, where are you? PM sent to Sean

 

[Hal Adams]

I will go along with Jeff, but leave the fix to Sean Hump too as it involves the satanic science of electronics!

Morning all ...

The front SAM does look after the turn signals ... there's no relay for the turn signals by the look of things

Do the hazards work ..? (from the switch in the centre of the dash)

 

[Big T]

SAM = ?

Checked it this AM. Starts right up. No Turn Signals. No Hazards. And no wipers or washer returned to the scene, whereas they were working yesterday.

signal acquisition module

you have 2, 1 in front, 1 in the rear

Apologies - should've mentioned what the were

Difficult to diagnose without hooking the car up to DAS (The computer based diagnostics) and costly to fault find purely by replacing suspected modules (which still need coding with DAS anyways)

Sounds like one or more of the following have been damaged by the reverse power hook up ..

Front SAM
UCP (Upper control panel - has the hazard switch in the middle)

What else doesn't work ..?
The roof switch, mirror adjustments and alarm features (if fitted) all go through the UCP

Wipers and washers are via the front SAM, as are the front lights and a few other bits on the front of the car..

You're going to need a diagnostic session ....

Hi @jbanks15 @Seanhump, Looking at the "Fuse Functions" tables from post #1 I notice that some items appear to not have a fuse number. For example front & rear foglights in the fuse number column it says "electronic". I was wondering how these circuits are protected if they are not fused? Are some circuits purely protected via Canbus and not fused as such?

 

[jbanks15]

Sean will reply but one of our posts I read stated that the fuse is builtin on the unit/light

 

[Col]

That's certainly not the case with my front fog lights. Unless the filament of the bulb doubles as a fuse! :laugh:

 

[jbanks15]

maybe foglights connect to another light power source? oh Sean, wake up!

 

[Seanhump]

Afternoon

The fuse for the fogs is electronic - it's in the Front SAM - it'll reset it's self when (assuming it's been blown) the short is no longer present.

 

[Squeeker]

Thanks again...Fuses all checked good.
