TC and HDC Failure lights on

I know there are plenty of threads (3 Amigos) on this issue, however I have only the 2 lights on no ABS warnings. The ABS is working fine been testing it on grass. I have changed the brake pedal brake switch and loom modification, with no change lights still on. Brake lights are working fine. I checked the OB2 and had P0120 which is the TPS sensor. This has now been changed, the throttle cable has been checked and adjusted. Still the lights remain on. I have checked the 1st gear sensor, its showing continuity when 1st gear is selected, also have power to the sensor. I have also checked the HDC switch on the gear shift.
I am now at a loss as to where tho look next. Does the clutch have a sensor to ensure it is engaged or that the pedal hasnt been depressed?
The car is a 2003 1.8 manual.

Wheel speed sensor maybe?

that would effect abs as well

Yep Wheel sensors will effect the ABS.
I have a brake pipe to change to the near side front at some stage so may try a working used ABS pump just in case a shuttle valve used in TC and HDC side is sticking.
One other thing I have noticed is the handbrake only comes up 1 click before the hand brake is on, could that if mall adjusted on the rear shoes effect it?
