STE/ICE DESCRIPTION AND OPERATION (Continued).

(b)

Prompting Message.

A prompting message is any action message to the mechanic.

It is

a signal for

you to

do something such as crank

the engine. For example, UEH tells you to enter the vehicle type identification number

into the VTM.

After the

operator action is performed, the

test will automatically continue.

Prompting messages are listed

on page 2-338.

(c)

Numerical Readout.

A numerical readout is the measured value in units of the

measurement being

made.

For example,

if you are measuring 0-45 VDC, 12.7 is volts dc.

If you are measuring 0-25 psig pressure, 12.7 is

psig.

The units for each test are listed on the flip card.

The numbers displayed in the VTM are always sensitive unless

there is a minus shown to make them negative.

(d)

Error Readout.

E001 is a representative error readout.

There are 17 different error readouts.

All error

readouts start with E.

All of

the error messages mean you must correct the problem before continuing
