    Hello to all. I have an Issue and any help would be appreciated:

    On the dash I have "-" ... N will not appear. Only "-" no Gears work.
    P1632 P1627 CAN timeout.

    Car is in Neutral
    Power WHT RED to TCU ...OK
    Key power YELLOW to TCU...OK
    Grounds BOTH ... OK
    ...
    F1 Pressure sensor. KEY on ...4.5 V
    Clutch sensor KEY on ...4.5V
    Actuator Plugs Grey and Blk, Key on (Both)... 4.5V
    >>>>Suggesting TCU 176552 Works!

    NOW, Also

    Jumped F1 Pump 12v+ at Relay runs great. OK
    *****F1 Relay not Priming, with door or When Key on.
    ORANGE WIRE AT F1 RELAY is Trigger Coil for relay.

    All Harnesses Appear Fine all Connections Checked three times. GREEN WHITE wires (CAN LINE) Connected.
    All fuses and All Relays Checked and tri LH and RH behind seats.ple swapped.

    Understanding the F1 relay orange wire
    • Function: The orange wire (pin 85) is the control input to the relay's coil. When it receives a signal from the TCU, the relay's internal switch is activated.
    Please, I need your input. I have no other tricks! Am I missing something here. One Questionable Item is the WINDOW LIFT ECU as the orange wire signal originates at the Drivers Door at striker when opened.

    Could CAN lines be the issue... Any Other Ideas.

    Your Help is appreciated! Thanks in advance
