TM 9-2350-247-20-1 INTRODUCTION STE/ICE–R (SIMPLIFIED TEST EQUIPMENT FOR INTERNAL COMBUSTION ENGINES-REPROGRAMMABLE) PROCEDURES—Continued 0107 00 E033 Error in entry of power test constants. Status Messages Status messages keep the operator informed of what is happening. DISPLAY MEANING .8.8.8.8 There is power to the VTM, and the display is working properly. This appears only for a short period after power is turned on. .9.9.9.9 VTM is reading a test value beyond its range. PASS Unit under test has passed test, or VTM has accepted a control function entry. FAIL Unit under test has failed test. CON Accepted control function input. AUE Numerical display is an average value. LO Engine speed below 1600 rpm during SI power test indicates the engine failed the power test. –1–1–1–1–1 VTM is busy. Numerical Readouts Units of measurement (psi, rpm, Volts, etc.) are not displayed. Numerical readouts indicate the measured value in units of the measurement being made. For example, if you are measuring 0–45 volts dc, 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 cards. Also, the readout will alternate between displaying values and displaying vehicle identification data (VID). Prompting Messages Prompting messages tell the operator to do something. After the operator action is completed, testing will continue. Some of the prompting messages and their meanings are as follows: DISPLAY MEANING UEH Tells the operator to enter VID on the TEST SELECT switches. CYL Tells the operator to enter the number-of-cylinders into the VTM. GO Tells the operator to crank engine. 0066 Tells the operator to set TEST SELECT switches to 99 during confidence test. CAL Tells the operator to release the TEST button during an offset test. CIP Tells the operator to apply full throttle in a CI power test. Confidence Test Error Messages Confidence test messages are displayed either as PASS or by a C followed by three numbers (#). A C### is an error message used by VTM repair personnel as an aid in troubleshooting. If a C### message appears during confidence test or during normal operation, go to confidence test fault isolation, TM 9-4910-571-12&P, for the necessary corrective action. 0107 00-10
