TM 9-2350-261-20-1 STE/ICE–R PROCED URE S (SIMPLIFIED TEST EQU IPMEN T F OR INTERNAL COMB USTION EN GINES REP ROGR AMMABLE) — Continued 0099 00 E020 No first peak information was detected by the VTM. E021 VTM cannot calculate result. Current is over current probe’s range, and VTM did not sample correct portion of data. E022 External voltage was detected in the circuit under test while measuring resistance. E023 VTM’s constant voltage source is not working. E024 Test is not valid for VID entered. E027 Error is entry of compression unbalance constants. E028 Test just entered cannot be used with control function 06. E030 VID entered conflicts with speed transducer attached. E032 Vehicle’s cranking speed is varying too much for a compression unbalance measurement. 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. 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). 0099 00-8
