LTX-12 Indicator Lamps

ON My LTX-12 ECU there are 3 indicator lamps on the front panel, Red, yellow and green. Can anyone tell me what these are for and what is supposed to light up with ignition? I cannot find anything in the manual other than maybe the yellow one is something to do with TPS calibration. Help appreciated.

Thank you
Lee

Thanks for the reply. So yellow and green should be on when ignition comes on. And yellow should be flickering maybe?
Cheers

Green should be on once key is turned and as soon as it starts to crank yellow should start to pulse. If there is any fault in the ecu the red light will flash to a code specific to the fault.

green is 12v

yellow pulses with ignition
.. a solid yellow solid ( with handset and dash unplugged, engine not running ) is for mechanical TPS calibration

red codes are faults,, often fleeting ,, bit prone to give home and ref errors with noise during cranking leaving up a false flag

.. holding down program mode button while in screen 33 for several seconds will reset the logs
