Overview

The Bosch 3631 is a heavy-duty logic probe tester designed for a wide range of automotive electrical system diagnostics. It features a multi-functional design capable of testing voltages from 3 to 26 volts. Bright red and green LEDs provide clear interpretation of voltage signals, including ground, power, and frequency.

This tester can diagnose fuel injectors, solenoids, and detect the presence of serial data and tach reference signals. It also performs output tests on sensors such as MAF, Cam, Crank, and Hall Effect VRS. Its high impedance input ensures compatibility with sensitive computer circuits and sensors.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
