When I first start-up my vehicle this morning,I got a strange readout on my fuel and temperature gauges.There were no readouts.I went ahead and shut-off the engine and then start it up again.This time,the gauges started to register.What might cause this intermittent problem?

M,
Test mode #3 will test the instruments...very cool.
- Select DLC A, terminal #7
- Press button three times, briefly but firmly.
you are now in DTM #3.
The control module will now test some instruments by making them generate
displays.
This indicates whether the gauges are working or any of them are faulty.
The control module activates the gauges simultaneously for 30 to 60 seconds. The LED stays on continuously thoughout the test.
Things to check:
- Fuel gauge should read 1/2 mark.
- Temperature gauge should just be on red.
- Speedometer needle should be vertical.
- The odometer should be activated eequivalent to a distance of 500m, appears on trip meter.
- Tachometer needle should be vertical
