Open the CIPO recordAbstract From the Canadian patent
An automated test system (10) makes voltage and resistance measurements. A breakout cable (34) is connected between the vehicle electronic control module (30) and the vehicle sensors and controls (32). Resistance measurements are made between a selected pair of connector pins of the breakout cable (34) by connecting a current loop (50) which includes a power supply (56) and a known resistance (R1 R2), through a first multiplexing circuit (70 72) to the selected, pair of pins. A voltage measuring circuit (52) measures voltage across the known resistance (R1 R2) and between the, pair of pins. The voltage measuring circuit (52) includes a second multiplexing circuit (82, 84) and a voltmeter …

Why it's free to use
- Filed November 6, 1991 and granted July 3, 2001. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended November 6, 2011.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 6, 2013.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
