LCD odometer/trip meter (Instruments)

LCD odometer/trip meter

The LCD has 3 different display elements: l Odometer. l Trip meter. l Selected gear (on vehicles with automatic gearboxes).

The odometer displays units in either miles or kilometres. It has a range from 0 to 999,999 units, only full units are displayed irrespective of the type of units selected, the display will stop at 999,999 units. TestBook can be used to reset the odometer. This is allowed only once and must be carried out before 150 miles (240 km) from new, after this distance the feature is disabled. The odometer may lose up to one km (0.6 miles) when the battery is reconnected, this is due to the software incorporated into the instrument pack to prevent anyone tampering with the odometer reading.

The trip meter displays units in either miles or kilometres and has a range of 0.0 to 999.9 units. The display rolls over from 999.9 to 0.0 units. Units down to one tenth of a mile or one tenth of a kilometre are displayed. The trip meter displays 0.0 when the battery is reconnected or charged from a discharged state.

A push button located next to the LCD is utilised to reset the trip meter to zero and to change the units from miles to kilometres. Pressing the button for less than 2 seconds allows the display to reset to zero. Pressing the button for more than 2 seconds changes the units from miles to kilometres and vice versa. The units will only change for UK, NAS and Canadian market vehicles.

The selected gear displays when the automatic gearbox is in park, reverse, neutral, drive 3,2,1, by using the letters or numbers PRND321 in the display.

The data input for the LCD odometer/trip meter is from the SLABS ECU for the distance input and from the BCU for the gear position. The instrument pack provides the earth path to illuminate the gear position warning lamp.

If a replacement instrument pack is required TestBook must be used to retrieve the odometer reading, so that when the new instrument pack is fitted the odometer reading can be programmed in.
