Does anyone have a list of the different read ing you can get from the odometer test mode.
For those who haven't found the test mode yet, start the car while holding down the trip reset button. First it will do a guage test, then as you press the trip reset button again it cycles through a number of reading. some i remember are exact speed, tach, oil and ater temp and others.
#.1..Gauge sweep. #.GAGE. #.Tachometer, speedometer, temperature and fuel. #.All gauges go through a full up and down pointer sweep smoothness check, which takes approximately 5
seconds.
#.2..Fill in all LCD. #.8888. #.LCD display built into Speedometer. #.Fills in LCD display therefore seeing if display functioning correctly.
#.3..Indicator bulbs. #.BULB. #.Instrument cluster illuminates indicator and warning indicators. #.Illuminates all the warning indicators that are controlled by the instrument cluster.
#.4..ROM level. #.rXXX. #.Instrument cluster read only memory (ROM). #.Displays the instrument cluster ROM revision level.
#.5..NVM level. #.EXXX. #.Instrument cluster non volatile memory (NVM). #.Displays the instrument cluster NVM revision.
#.6..DTC. #.XXXX or NONE. #.Diagnostic trouble codes (DTCs). #.To list the DTCs stored, press the RESET button. ..REFER to the instrument cluster diagnostic trouble code (DTC) index below. ..The DTC codes will scroll through if there is more than one.
#.7..Road speed mph. #.XXX.X. #.Speedometer. #.Displays the speed signal input in mph.
#.8..Road speed Km/h. #.XXX.X. #.Speedometer. #Displays the speed signal input in Km/h.
#.9..Engine speed. #.XXXX. #.Tachometer. #.Displays the tachometer input signal (RPM).
#.10..Fuel volume. #.FXXX. #.Fuel sender system. #.Displays the fuel volume signal input.
#.11..Coolant Temp. #.XXXC #.Engine coolant temperature. #.Displays the engine coolant temperature signal input.
#.12..Battery Voltage. #.bXXX. #.Battery Voltage (t). #.Displays battery voltage input.
#.13..ABS fail. #.Ab-[H/L]. #.ABS system. #.Displays ABS raw cluster input. (H = open-circuit, L = ground).
#.14..Electronic Brake Distribution Failure (EBD). #.Eb-[H/L]. #.EBD system. #.Displays EBD raw cluster input. (H = open-circuit, L = ground).
#.15..Illumination. #.IL-[H/L]. #.Cluster and instrument panel illumination. #.Displays instrument cluster and instrument panel illumination. (H = ON, L = OFF).
#.16..Crank Sense. #.Cr-[H/L]. #.Cluster and instrument panel crank sense. #.Displays Cluster and instrument panel Crank sense. (H = Ignition, L = Ground or over-charging). #.(Crank sense it the Pos I (Accessory) supply to the cluster. If this is missing then the cluster will remain
dead for about 20 seconds after key on. Then it will function normally. This can happen when someone fits a
radio and blows the accessory fuse).
Note: Additional tests are available after number #.16 but are not useful for diagnostics.
Note: Later vehicles had a "cost reduced" cluster that had a different Engineering Test Mode layout. These came in
about 03-53 reg, and can be distinguished by only the symbol lighting up in the tell tale rather than the whole
lot. (LEDs rather than bulbs). These clusters used stepper motors for the gauges rather than the air cored ones and did not have a Gauge
