Sensors, remotes & sockets
I've just bought a 1995 Volvo 960 3.0 auto. The car's condition is immaculate, but I need help with three problems. The first is that I need to fit reversing sensors, but I am not sure at what position to fit them on the bumpers. The second is that I have two remotes, but the batteries are missing, so I cannot use the remote locking system; I need the sequence to make the remotes work when the new batteries are fitted. Third, I am wondering if there is an OBD socket and where I should look for it? There are no problems yet, but I would like to be prepared. Graham Moore-roberts The position of the sensors is quite difficult to get right. Ideally, they should be fitted just below the centre line of the bumper. In practice, this is not practical because of the reinforcing bar fitted behind the bumper cover. By feeling inside of the bumper you should be able to locate an area just below the reinforcing bar behind the cover where the sensors can be fitted. Most sensors are supplied with offset washers that will help align the sensors to keep them level on a slanted base.
Regarding the remotes, when the new batteries are fitted, the fobs will need to be reset on your vehicle as follows: 1. Ensure all remotes are to hand; sit in the vehicle with the door closed. 2. Switch the ignition on and off four times within 10 seconds. 3. Switch on the ignition again and, within 30 seconds, press either the lock or
unlock button of each remote fob. 4. Turn off the ignition. The remotes should now operate.
You’ll find the OBD socket (DLC) under the bonnet – this is not the later EOBD unit that was fitted to vehicles built from 1996, but an earlier Volvo system. The DLC (Diagnostic Link Connector) should be located under the bonnet at the nearside of the vehicle. It is a small black box with a link wire attached.
To read the codes, locate the box and open the cover – a small LED should be visible. For engine fault codes, place the link cable into position two for fuel injection codes and position six for ignition codes, then turn the ignition to position two. Press the button on the socket for more than one second, but less than three. The LED will flash a series of three digits followed by a three second gap. Write down the codes. If no codes are present the LED will flash 1-1-1.
To clear the codes, read the codes as above, then press and hold the button for five seconds or more. When the LED illuminates, release the button and depress it again for another five seconds or more. The codes should now be erased and can be checked by reading them off again.
