Replacing Components - Instrument Cluster
+38: Replacing components - Instrument cluster
- Expose dashboard
Warning! Cars equipped with a Supplemental Restraint System (SRS) must be treated extra carefully when repairs are being made. This is to help prevent:
- 1. Injuries when carrying out a repair.
- 2. Damage or malfunction of the SRS system.
Repair to either the SRS itself or a related system or component must be carried out by an authorized Volvo workshop.
- Remove battery - lead.
Removing cover
- Remove glove compartment holders.
- Remove the six screws holding the glove compartment and remove the glove compartment.
- If a passenger-side airbag is fitted, remove the 4 mounting screws from the underneath of the module.
- Remove cover washers and screws to side defroster vents.
- Remove panel vents as follows: turn down and pull out or pry off gently with a screwdriver at the side and pull out. Remove both vent and air duct on RH side.
- Remove speaker grills on both sides.
- Remove speakers. Push plastic plugs down in center.
- Undo connector.
- Unscrew the 12 mounting screws holding the cover panel. Cars fitted with passenger-side airbags have a screw missing at the top of the glove compartment. Cars not fitted with passenger-side airbags have a screw missing at the top by the RH speaker (marked 2 in picture).
- Lift cover panel off carefully.
Once you have removed the cover panel, you can connect the test box and use it for fault-tracing with the dashboard.
Dashboard, removal/replacement
- Remove both dashboard connectors and the connector to trip computer if any.
- Undo both clip-on locks at the top and lift the dashboard out.
When replacing the dashboard:
- VDO: Code for right market and program in mileage and select service interval as shown in Diagnostic test mode (DTM) 5 - Reading off data:Diagnostic test mode (DTM) 5 - Reading off data and Diagnostic test mode (DTM) 6 - Data entry:Diagnostic test mode (DTM) 6 - Data entry .
Note! It is important to do this in the right order and as shown under DTM 6.
- Read off and erase any DTCs.
- YAZAKI: Write in the service and warranty manual that the dashboard has been replaced. Note down the gauge readings and the date the replacement was made.
- Reassemble in reverse order.
Note! Make sure that the flap on the underneath of the cover fits into its slot.
Dashboard, replacing components.
VDO.
Note! Points to note when working on dashboard: Cleanliness: workplace must be free from dust, dirt, oil, solvents etc.
Always wash your hands before taking the dashboard apart. Do not use hand cream or hand lotion after washing. If using gloves, these must be thin cotton cloth. Synthetic materials could lead to a static buildup.
Printed circuit board must not be exposed to static electricity.
Do not touch printed circuit board or instrument scale surfaces.
Do not move needles so they change position. They are calibrated at the factory. Moving them may make instruments read wrongly.
Replacing individual components
If dashboard is not working, this may be because the fuse has blown.
- Remove printed circuit board and check fuse on the inside.
Electrical faults are very likely to be due to faults in the printed circuit board.
- Change the printed circuit board first.
- Assemble and connect dashboard.
- Test dashboard in DTM (see DTM 1 - Self-test ).
- If fault persists, replace instrument panel.
Dismantling instruments
- Remove time/temperature/trip computer module which is located in the lower center. Undo the two screws and the connector.
Note! Do not pull on leads: hold connector and pull it out carefully.
- Remove cover. Undo the 11 screws marked A and the three marked B.
The screws marked B hold the odometer to the baseplate.
- Lift printed circuit board off of baseplate. The printed circuit board is pressed onto the baseplate and must be removed with care.
- Undo odometer connector.
Caution! Place circuit board on anti-static mat.
Replacing fuse
- Replacing fuse. Fit fuse to outside of printed circuit board. The arrows in the picture show the two holes which act as screwholes for the new fuse.
Use the fuse kit supplied as spare, part no.: 9128110.
If the fuse has blown, this may be because something somewhere else is wrong. Follow fault-tracing procedures.
- Remove baseplate from instrumenthousing. Undo the 9 screws as shown in the picture and the 2 screws in circuit board.
- Lift off instrument panel.
Note! Do not touch instrument panel or gauges.
Note! If circuit board was not earlier disassembled, carefully coax the instrument plate from baseplate.
- Remove odometer and reset button.
- When replacing odometer, pull it straight out of trip meter.
Replacing symbol plates
- Carefully remove the symbol plates mounted on two plastic pegs on the instrument casing.
- Replace and install the new symbol plates.
Assembly
- Insert odometer in baseplate.
- Assemble instrument panel and baseplate.
- Make sure that reset button is in right place in instrument panel and that instrument panel fits correctly onto baseplate. Press together.
- Make sure to run the odometer lead and connector through the square hole.
- Assemble instrument casing.
- Insert baseplate and instrument panel in place and screw in the 9 screws.
Install printed circuit board
- Connect odometer leads. Connector will only fit one way round.
- Install printed circuit board by pressing on bulb holders so contact pin goes in
- If a new printed circuit board is fitted then the bulbs shall be moved over from the old one.
Caution! To seat circuit board on baseplate, press on cover only, not on circuit board.
Install cover
- Fit cover and screw dashboard together with screws A and B as in
picture ( 11 + 3 ).
Install module
- Insert time / temperature / trip computer module, screw it fast with the 2 screws and connect the connector.
Reinstall dashboard in car
- After connecting the connectors, fit a new contact protector to the 30-pin connector, part number: 912 8111.
- Reinstall panel and other components in reverse order as per Instrument cluster: Expose dashboard.
When replacing printed circuit board
- Diagnosis: Read off and erase any DTCs and code for market,
program in mileage and service interval as per section in Diagnostic test mode (DTM) 6 - Data entry:Diagnostic test mode (DTM) 6 - Data entry.
Dashboard, replacing instrument model / symbol panel.
Applies to YAZAKI model.
Note! Points to note when working on dashboard: Cleanliness: workplace must be free of dust, dirt, oil, solvents etc.
Always wash hands before dismantling dashboard. Do not use hand cream or lotion after washing. If using gloves, these must be thin cotton cloth. Synthetic materials can cause static buildup.
Do not touch printed circuit board or gauge surfaces.
Do not touch dials so they change position. They are calibrated at the factory. Moving gauges may cause them to read incorrectly.
Dismantling dashboard
- Remove time / temperature module center bottom. Undo the two screws and the connector.
Note! Do not pull lead: hold connector and carefully pull straight out.
- Remove screws from printed circuit board and remove board: 11 screws marked A, 4 marked B and 6 marked C, as per picture.
- Remove screws from baseplate and lift baseplate off: 9 screws marked D in picture.

Install time / temperature module and screw in place and connect connector.
Replace fuse
- Replace fuse. Fit fuse on outside of printed circuit board as in picture. Use fuse kit supplied as spare.
- Check for open-circuit in fuse with an ohmmeter. Ohmmeter should read infinite resistance. If fuse has blown, this may be due to a short-circuit somewhere else. Follow fault-tracing procedures.
Reinstall dashboard in car
- Test dashboard.
- Install new contact protector on 30-pin connector (part no.: 9128111).
- Reinstall cover panel and other components in reverse order as per Instrument cluster:Expose dashboard.
