Yes.
If the friend's unit is an OBD II system, then it will not work on your 1990 LS.
If the check engine light is illuminated on your Lexus, look under the driver's side of the dashboard for the diagnostic check connector and short terminals TE1 and E1 in the connector, turn the ignition to on, and count the flashes of the check engine light.
