Test Function No. 2 - System Test
- Test function 2 is not locked and can accessed immediately. After selection the instrument pack automatically activates all displays and analogue gauges. This test will only be performed with the ignition in positions I or II and the engine not running.
- The backlighting of all LCD's are activated.
- All segments for the odometer, trip meter, ambient temperature and service interval indicator are illuminated.
- All warning lamps are illuminated.
- A pixel test of the message center is alternately performed to display a 'chess board' pattern. The pixels are alternately illuminated at intervals of 1.25 seconds. The trip meter display alternates between km and miles and the ambient temperature alternates between °F and °C.
- The general brake warning lamp alternates between an amber and red output.
- All analogue gauges are activated and travel from the left stop to the right stop and back to the left stop.
- When all gauges have returned to their left stop all displays remain illuminated. A second activation of the analogue gauges follows, but this time the needle pointers stop before the right stop position. During this gauge cycle, the instrument pack performs self diagnostics on the gauge operation and records fault data if necessary. This diagnostic check of the gauges is only performed during test function 2 and the data can be retrieved using T4.
- When the second gauge cycle is complete, normal instrument pack display is resumed.
