Opel Corsa C z12xep IMMO
Hello, is it possible to bypass / turn off IMMO in this car?
Opel Corsa C 2005, 1.2 XEP engine, IMMO unit UN Car was missing ECU - somebody stole it, dont know why... Bought second hand ECU together with IMMO unit and keys. Placed in car, adapted to VIN and dash, there is no error in IMMO, BCM, dash, engine. Seems ready to start. Also when I turn a key in ignition, after a while, immo icon disappears. So far so good... But car does not start, it cranks but thats all. After each crank this try "B3059 - (0) No Engine Request Received - Present" appears in ECU DTCs. Dont know where is the problem since i already tryed 2 different ECUs, everytime programmed them correctly so that IMMO is seeing valid key, permits start, all values in opcom looks promissing but after each crank try, this problem appears. Did anybody experienced the similar issue? Is there any way how to bypass the immo or just switch it off? |

If I'm wrong, someone correct me.You must have both pin codes.If you know the pin code of the car, reset -bsm-dashboard. In immo you don't delete pin and keys.With a pin code from the car, you reset the bsm and dashboard.Write down the new pin code from the ecu and immo you bought. |

UN very possible faulty. You can use LS units, they are usually bulet proof. B3059 will set when both ecm and immo do not talk to eachother within 1s or so from ignition on. I’ve seen faulty ignition switches and or ignition relays (the yellow ones) doing this, but more often faulty UN.

Yeah... ,the case is - i have tryed even a second UN unit...
I bought a complete set of UN unit, ECU, cylinder lock and keys... after pairing to car, still this issue. But what i just dont understand is as i explained - all seems ok, no error light, no error code after ignition on, only that error appears after trying to start the car.
