When does the TCC disengage in a manual transmission?
The TCC is very similar to the clutch in a manual transmission. When engaged, it makes a direct physical connection between the engine and transmission. Generally, the TCC will engage at about 50 mph and disengage at about 45 mph. The TCC solenoid is what actually causes the TCC to engage and disengage.
Why does the ignition module not switch to est mode?
If the by-pass line is open or grounded, the ignition module will not switch to EST mode, so the EST voltage will be low and Code 42 will be set. If the EST line is grounded, the ignition module will switch to EST, but because the line is grounded there will be no EST signal.
