Operational checks

Speedometer


1. Connect an ISAT Scan Tool and select "TEST FUNCTIONS" followed by "SPEEDOMETER TEST". If in proper working order, the speedometer needle should move from 0 to 250 km/h.

During this test, operation of the radio's speed-dependent volume adjustment can also be tested.

2. By selecting "ACTIVATE" and then "SPEED" on the ISAT Scan Tool, the desired speed can be entered. The speedometer needle will then move to the corresponding figure.


Odometer and trip meter

The odometer display consists of a separately replaceable unit. Mileage information is stored in the instrument unit. On replacement of the display unit no resetting will be necessary as the current odometer reading will be obtained automatically.

If the odometer display lighting is weaker on one side than on the other, it may be because one of the two bulbs behind the display is faulty.


1. Connect the ISAT Scan Tool and select "TEST FUNCTIONS" followed by "ODOMETER TEST" or "TRIP METER TEST". This will cause all the segments in the relevant meter to light up (it will show eights). If any segment in any of the eights is missing, the display unit is faulty.

2. Using the ISAT Scan Tool's "ACTIVATE" function followed by "ODOMETER" or "TRIP METER", the desired number can be entered (000000-999999 and 000.0-999.9) and shown on the relevant display.

Note

All six or all four digits must be entered.



Tachometer


1. Connect the ISAT Scan Tool and select "TEST FUNCTIONS" followed by "TACHOMETER TEST". If in proper working order the tachometer (rev counter) needle should go up to 7000 rpm and then drop back to 0.

If BLACK PANEL has been activated, the tachometer should light up when the needle enters the red zone and go out when engine rpm drops and the needle leaves the red zone.

2. Using the ISAT Scan Tool's "ACTIVATE" function followed by "ENGINE SPEED RPM", the desired engine rpm can be set and the tachometer needle will then indicate the corresponding figure.


Turbo pressure gauge (turbo/APC)


1. Connect the ISAT Scan Tool and select "TEST FUNCTIONS" followed by "TURBO GAUGE TEST".

If in proper working order the needle of the turbo/APC gauge should move from left to right across the scale and back again.

If BLACK PANEL has been activated, the tank/temp/turbo gauges should light up when the turbo gauge needle enters the red zone and go out about 10 seconds after the needle has left the red zone.

2. Using the ISAT Scan Tool "ACTIVATE" function followed by "TURBO PRESSURE", the desired turbo pressure can be set and the turbo/APC gauge needle will then move to the corresponding part of the scale.


Fuel gauge


1. Connect the ISAT Scan Tool and select "TEST FUNCTIONS" followed by "FUEL GAUGE TEST".

If in proper working order, the fuel gauge needle should travel from empty (R) to full (F) and then back to empty.

If BLACK PANEL has been activated, the tank/temp/turbo gauges should light up when the needle enters the red zone.

The warning lamp should light up when the needle enters the red zone.

2. Using the ISAT Scan Tool's "ACTIVATE" function followed by "TANK CONTENTS", the desired fuel level can be set and the fuel gauge needle will then move to the corresponding part of the scale.


Temperature gauge


1. Connect the ISAT Scan Tool and select "TEST FUNCTIONS" followed by "TEMPERATURE GAUGE".

If in proper working order, the temperature gauge needle should move from the lower part of the scale to the upper part.

If BLACK PANEL has been activated, the tank/temp/turbo gauges should light up when the needle enters the red zone.

2. Using the ISAT Scan Tool's "ACTIVATE" function followed by "COOLANT TEMP.", the desired temperature can be set and the temperature gauge needle will then move to the corresponding part of the scale.

Note

Temperature gauge indication is not linear. Between about 80°C and 115°C (xx and xxx °F) the needle is horizontal on the scale.
