I read a post describing similar symptoms to this fault ,but i think it was a vectra or smaller engined Omega. The speedo is dropping out & the TC & ABS lights come on.When checking for codes the Autodiagnos multitester Pro can't communicate with the ABS ecu,although it will communicate with the transmision ecu & logs code P1844(Ign.?Inj. cutoff circuit(according to AD description on screen)).When i checked the code on the Gendan website it came up with another description :Engine coolant temperature circuit(ECT),Torque control -signal out of range. I think that the ABS module is faulty,but a new one from Vauxhall is £953 + vat, so i'd like to be certain that i'm correct, otherwise i don't think the customer will be too happy if i'm wrong.I think he will want a second hand unit anyway. I have checked the earths & feeds to the unit & don't get any fault codes in the ABS ecu when i can communicate with it although the lights are then off. When i first checked the codes ,P0758 shift sol.B (2-3) circuit, P1605 Replace or reprogram ECU, Were also listed with the P1844 (twice), but these codes didn't reappear after clearing. Any suggestions? Regards, Andrew
