Sounds like your car has a REAL TCS problem. It should NOT go into LHM when TCS is activated, rather the TCS should activate (orange ligt to the left on the dash, not the dreaded red TCS/CTRL on the right side of dash.
By disabling the TCS you won't get around the LHM problem. Much simpler to fix the real problem. Its here somewhere,....
(1) vacuum hoses
(2) saftey valve
(3) pedal potensiometer
(4) throtle body
(5) ABS and/or TCS ECU
(6) wheel speed sensors
You can do 1 & 2 yourself (new hoses, correctly routed and attached, 30 ohms across saftey valve pins). Then take it to Saab and have them read & reset the ABS and TCS ECUs. On my 93 CSE, the ABS scan showed flakely wheel speed sensor. Saab reset the computer, I changed the WSS. 70,000 miles later, not one incident of LHM.
