I don't know how to de-activate the entire alarm system, but disconnecting the speaker (so that the alarm is silent) is easy. Simply lift the hood and identify the speakers at the very back (if I remember correctly, each looks kind of like a tuba; you can't miss them). Somewhere very close to them is a plug. Unplug it and the alarm will no longer sound. The car will still go into anti-theft mode by blinking lights and refusing to start until you lock the doors; you just won't hear anything.
its a 4 digit code to enable radio operation,best bet is to pull radio out and get serial number from sticker on top of radio and call Volvo dealer with radio model # sc-815 or sc-816 and serial number and they can run thru computer and get your code
there are two little black buttons on the side of the clock you must push in both of these at the same time. also changes from Fahrenheit to Celsius and vice versa.
yes it will ,its an interference engine meaning that pistons will hit valves bending them.to cure this problem is to either purchase a set of new valves or you can buy a new engine or you can avoid this by just simply have the timing belt change good luck peace.
To start, the Ignition key must be in position II, engine not running. Locate the two diagnostic sockets just inboard of the washer fill cap. The "A" connector (shown above) has a jumper that is stored in the lid of the "A" diagnostic connector. The jumper is used for both diagnostic connectors. Listed below is the information retrievable from the various connections. A1 Transmission B1 Climate Control A2 Fuel System B2 Cruise Control A3 ABS B5 SRS A5 TCU (Transmission Control) B6 Power Seat A6 Ignition System A7 Combined Instrument Normally "Check Engine Light" information will be found in A2. Put the jumper into A2 and push the black button for one second. Count the red LED light as it blinks back information, blink, blink, pause, blink, blink, blink, pause, blink, blink, is an example of the response you would receive. 2-3-2 would be the code retrieved, now push the button again for one second, again count the blinks, keep checking for codes until one of them repeats, this means you have read all the codes. Now to clear the codes, push and hold the button for 6-7 seconds, release and as soon as the LED comes on push and hold the button for another 6-7 seconds. Now push the button for one second and read the codes again, you should get 1-1-1 (no faults). You Must Read All Codes before Clearing. Turn the ignition off and then start the car, the check engine light should be out. It is always a good idea to check for codes, clear them and then drive the vehicle to see if they return before replacing parts. The transmission can ask the check engine light to be turned on, so if you try clearing A2 codes and they wont go away try reading the transmission (A1), clear them , and then go back to A2.
After contacting a Volvo dealer, they recommended the Haynes series of manuals for the 850, each section details the codes and faults detected.
it might be the engine idler pulley or power steering pump. if it's e.i.p.
bearings gone bad. replace it. the p.s.p. may have air in the lines. top
fluid off with lucas power steering treatment, turn wheels loc to loc
make sure front wheels are off ground repeat @ 10 times. inspect
return hoses clamps reservoir
if the noise is a squeeling sound, check the drive belt, if worn change it @£17 if the noise is a squeeling sound, check the drive belt, if worn change it @£17
If the transmission is not in a lower gear than "drive" when the arrow flashes, or your transmission is not set for "winter driving mode", you could be experiencing a PNP switch going bad. The PNP is a switch that sits on top of the transmission near the shift linkage. It's a pain to to istall and costs about $120 most places.
Look at

It says it all for a 850!
the relay needs to be replaced. you will find it behind the hazard switch (attached to the switch - a long skinny thing)
I looked forever till someone told me where it was. Even the Volvo parts guy didn't know and Lawrence Volvo of Walnut Creek, CA would not tell me...
The oxygen sensor is used to infer the rich/lean mixture of the engine. Without a signal from the sensor the computer will default to a general mixture to allow the engine to run. Overall I'd expect strong smelling exhaust, loss of power, poor fuel economy, and the service light to be on.
You can troubleshoot the oxygen sensors easily with a digital volt meter. These sensors have either 1 or 3 leads. For single lead sensors connect a digital volt meter to the single lead, leaving it in the circuit, don't unplug it, or cobble a connection so it stays in the circuit with the car. Measure between the sensor and ground on a 1 volt scale. You should see this value vary between about .2 and .8 volts on about a 1 second interval. This only is applicable if the engine is fully warm!
The 3 wire sensors have a heater built in to get them to operating temp. sooner, thus you need to find the sensor lead from the heater lead. Obviously the heater lead is either ground or 12 volts, so the remaining lead is the sensor.

Do you have your terminology right....The injector relay would be the computer right???
The fuel pump relay could cause that problem!!!!
good luck and let me know
To open the trunk of a 1996 Volvo 850 glt from the inside first you need to fold down the rear seat, remove the trunk lid panel so you can access the rods. Move each rod up and down until you find the one that releases the trunk.
search the web. there is someone in California who does nothing but fix ABS controllers. His website explains how to remove it and he sends an email explaining how to re-install it. best $125 I ever spent on my car (local mechanic quoted $500).
This is water in the oil, usually caused by head gasket failure
Could be a crack or hole in the pickup tube. I had that problem in a '84 940GLE.
10.6 for an automatic, add another 1.5 hours for a manual (clutch adjustments, etc...)
Don't forget that there are always extra part costs.
Trouble code P0611 means: Furl injector control module - performance
The Volvo 850 1997 fuel pump relay is under the fuse box compartment, you would need to take out the upper portion of it and then you would be able to easily find it undeath. elyunque000@yahoo.com
The obd2 connection is located right above the gear shifter. There is a cover that looks like a coin holder that pulls up and the connector is under it.
