The ABS snapshot will help to isolate problems caused by the speed sensor signals which may cause intermittent operation of the ABS system. The ABS SNAPSHOT mode captures data before and after a trigger condition.
If "MANUAL TRIGGER" is selected, the TECH 1 will wait for "ENTER" to be pressed before storing speed sensor information. When TECH 1 is waiting for "ENTER" or "F9" to be pressed, a "W" will be displayed in the lower righthand corner of the display. While the TECH 1 is waiting for the trigger, it continuously stores ABS speed sensor data. The TECH 1 can store up to 81 samples of ABS data before the trigger, and 81 samples after the trigger. If more than 81 samples occur before the trigger, the oldest data will be discarded. It takes approximately eight seconds for the TECH 1 to store 81 samples.
As soon as "ENTER" or "F9" is pressed, the TECH 1 will begin to store speed sensor data, this is indicated by an "I" displayed on the screen. When data storage is full, the data point when the "ENTER" button was pressed will be displayed indicated by ")" on the display.
To view the speed information that was stored, use the UP ARROW and DOWN ARROW keys. The numbers on the display indicate the sample number relative to the trigger. An "+1" on the display indicates the first sample after the "ENTER" button was pressed. An "-1" on the display indicates the sample proceeding the time when "ENTER" was pressed. By selecting the up and down arrow keys, all of the stored data can be displayed and examined for conditions which might indicate a problem. While displaying data, select F7 to convert English to Metric or select "ENTER" to convert number in the righthand lower corner of the screen to time in seconds.
If "AUTOMATIC TRIGGER" is selected, the TECH 1 will store data which may deviate from normal operating conditions but may not set a diagnostic trouble code. For example, when driving over bumpy roads or railroad tracks, the wheel speed signal may change rapidly or drop out. This condition may be caused by loose connections or intermittent wiring problems. Using the "AUTOMATIC TRIGGER," data will be stored when the TECH 1 recognizes that a wheel speed signal has deviated from it normal operating range. While the TECH 1 is waiting for a trigger, the "ENTER" or "F9" button may be used to force a trigger. While displaying the information, the cause of the trigger can be displayed by selecting F3.
If "MANUAL TRIGGER" is selected, the TECH 1 will wait for "ENTER" to be pressed before storing speed sensor information.

- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
