Page 9: Determining Wire Function
Automotive Diagnostic Tool Determining wire function In the vehicle main wire harness, individual wire function may be determined based on the following readings: The POWER wire (continuous un- switched source wire) will register at approximately +12 or +24 volts in any... -
Page 10: Locating Tach Signal On Alternator
Locating tach signal on alternator If a tach signal wire cannot be found or signal is weak, it may be necessary to determine the best location to fasten the permanent Digital Tach Sensor (DTS) on the alternator: Turn on handset and press FUNCTION button until reaching the LOCATE TACH function, indicated on display by “TACH 000”... -
Page 11: Measuring Tach Signal
Automotive Diagnostic Tool Measuring tach signal To determine if there is a good signal from the tach signal wire, perform the following steps: Turn on handset and press FUNCTION button until reaching MEASURE TACH function, indicated on display by “RPM 000” and comma in position 3. -
Page 12: Simulating Tach Signal
Simulating tach signal In the case that the alcohol interlock registers a “Tach Fault”, this function is used to determine if there is a problem with the tach signal (either in the wiring or digital tach signal) or the ECU itself. If a tach fault occurs, cut the tach signal wire and connect red multimeter probe to wire leading to ECU. -
