    faster and easiest way for decode:

    cut immo line (pin 37 1.4 and 1.6, pin 35 1.8 and 2.0L)
    find flash
    connect ecu to car and switch ing on
    short circuit to ground for few to ten times pin 22 for flash 28F512/29F010
    short circuit to ground for few to ten times pin 23 for flash 27C512
    start the car

    Hi Members:

    I tried the method #1, light stop blinking and now is always ON, I tested the ecu on bench, the 2 pins for injection control are working (pin 4 pin 30) fuel pump relay is workin too, but I don?t have coils activation signal on pins 28 and 29.

    Do any of you had this problem ??

    Maybe bad TMS erasure or bad coils stage output ??

    thanks

    hi to all,

    Hi there Guys.....
    I have a problem. This is the second time I have a Megane Scnenic with the FENIX 5 ecu. When I connect the ECU as per diagram the MIL Light Doesn't Flash nor come on. I Checked all wires but nothing.
    Does it require high power or what? I am using a 12V 7AH Alarm Battery and these small Jumper leads with Crocodile Clamps on the ends.
    Any Other suggestions???

    Im sorry for waking this old topic but im hoping that someone can help me...
    Problem is:

    Renault Megane Coupe 1998 2.0 16v 103kw

    Replaced uch(ucp) from inside the car, in top of pedals but car wont stard because immo flashing red on dash. After that some mechanic comes with diagnostic and turn the immo off and flashing light gone but car again wont start just cranking. After this solution i see that "zig zag" flashes all the time and now we cant connect diganostic to read ecu and even ucp(uch)...

    Can anyone point me in right direction do I maybe need to do solutions from start of topic after turning immo off on diagnostic?
    And I need to to this can someone post solutions how to do it because i cant download attached files from start of this topic...

    Thanks in advice
