best is tell all that works and does no work, engine and all this endlessly electric on this car. all matter for faster diagnosis.
so car starts and runs ok> no told good things. and matters huge.
- engine running, and gen/charge/battery lamp out????
- check engine lamp out running.??
- check fuses first.
- scan he car next using oBD2 scan tool is next.
what means dash light, of vast and cluster. (cluster dead?)
odom dead , gauges dead, keyon check cluster error lamps dead?
parks dead 4 corners
turns dead 4 corners.
all head lamps dead, high and low beam and FLASH mode.
hazard lamps dead all 4 corners.
details matter.
ok brake lamps good rear,
1 good thing.
answering for USA only cars me. ok?
fix bad head lamps first as those work key on or OFF or missing. it is the simple path so most times fixing this gets the rest. see?
I have the schematic up for your car NOW 14 pages deep
buy the service manual>?
the
MTIP brain runs all this.
there are no fuses for any of those lamps, the THE MTIP HAS DIRECT DRIVE REGULATORS TO DO ALL THAT.
YOU HAVE 1 OF 2 PROBLEMS on THIS CAR
FUSES BLOWN TO THE MTIP
OR sCANS SHOW
COMMUNICATIONS ERRORS TO THE MTIP
OR FROM THINGS THAT HAVE SWITCHES LIKE THE CLUSTER HAS.
KEEP IN MIND, I SAID ENGINE RUNS AND ALL ELSE. DOES BUT YOUR SHORT LIST.
WE CALL THAT THE BODY BRAIN IS DEAD.
it can not do its job and most or all body parts, lamps, etc.
wise is check all fuses first
then scan it ,USA OBD2 scan tools 2008 tool or newer
yes older cars the MTIP can get wet rust up and fail.
but i look at that and all fuses to in and in it.
good fuses
no comm errors seen scanned on CANBUS network
let me say this about comms
you turn a switch and it is wired to the key brain or cluster brain
and that brain tells the MTIP to turn on a LAMP say PARK
and if comms fail now , all this is Impossible to know
lacking a SCAN TOOL
B16xx errors from the tool>? means PARK failed. (lamps on)
I will not read all 50 pages of schematics to hone in on cause.
example
key off
battery reads 12.6vdc rested, never 10v or less ever.
turn on parks
if parks dead, 4 corners and sides and license plate lamps
the MTIP just failed.
scan the car, if comms failed (but scans do work)
the problem is way more serious. can bus errors are not allowed.
most switches here wire director to the cluster brain
the cluster must not be dead. and it sends data(network) to the MTIP and it turns on say park lamps, direct driven
too 20mins online to get the cluster brain schematic up.20 pages just it.
ok that is all and USA cars, only ,me.
PARKS WORK KEY OFF TOO AND BATTERY MUST BE OVER 10V.
12.6VDC GOOD KEY OFF.
