    Code P1602-002 - Power Supply to terminal 30 voltage too low

    Code P1602-002 = Power to Terminal 30 voltage too low. The wiring diagram below shows Relay J271 and J623 ECM - on my Audi Q7. Per the manual with the ignition on...there should be battery voltage at Relay J-271 socket 30, however I'm getting nothing. I have removed the wiper arms from the transmission, and pulled off the windshield cowl cover, so I can now physically access the ECM. I think I need to remove the connector to the ECM and check the wire continuity, but I am unsure how to remove the tamper-proof retaining screws. Guidance is requested.

    Hello Jack....the last full auto-scan was a month ago (below)...the Q7 has just been sitting since that time. I kept getting he EPC light, so I disconnected components to see if I could find out what was triggering it, my efforts were not conclusive. So the Q7 has both MAF's and both HPFP's disconnected. I also have the air intake tube going to the throttle body removed so I could access the wire harnesses at the back of the engine. For fun...wise or not....I decided to see if it would start this morning, and it did immediately...and ran quite smoothly for a few seconds, and then resumed it's rough idle, it rev'd up fine. I checked the engine management system to see what codes were there, and it showed MAF's as signal too low, Bank #2 fuel pressure regulator no signal, and the P1602-002 power to terminal 30 voltage too low....so I figured I'd tackle this low voltage issue first.

    Please sir, before anything else, take the engine ecu out and apart to inspect for water ingress.
    If corrosion is present and you need an ecu with data transfer we can help.

    You absolutely must check this first, to rule out the fact there could be nothing possibly wrong under the hood.


    This is a common issue......

    The ECU physically looks good from the outside, the bottom panel is nice and shiny. Never the less I will remove it. How do I remove the ECU Connector retainer "bolts"...? The manual says to use a heat gun to loosen up the thread locker used at the factory and then use vice grips to twist out the bolts. I'm tempted to carefully grind the heads off.....

    Here are picture of the ECU, it has the usual oxidation and stuff on the top side, but the underside looks pretty good.

    What about after the rear cover is removed and be careful doing it?
    It can always be resealed.
    If dry and clean I recommend bagging the controller when putting it back with air snorkel tube.

    I will try and use a dremel and slot the head of the tamper-proof screws. Then I will remove the brackets around the large multi-pin connectors, and test the gray/black wire going to J271 Relay terminal 30 for continuity. If all checks out okay....I'll will post the results and go from there with your guidance. Thank You Jack.

    Your welcome .......and FYI that rotted torx screw is a sign water is present.

    Often the power supply driver gets wiped in these MED9 units which switch's the consumer and power supply relays.

    It additionally bothers me that 0x09 is not present after quick review.....

    Please post more data from the JPPSG format.

    The white PR code tag from the spare tire trunk area, and or service books first page.

    According to what I see in the microfilm it should have these central electrics.

    Based on this I would want to know the status of the Ignition switch and all terminal relays.

    More to do but here is where I'm at right now. I managed to remove the brackets holding the harness to the ECM. I then checked the continuity of the 0.5mm gray/black wire going from J271 Relay socket terminal 30 to the ECM Connector T94 at position #69...I read 1 ohm resistance which to me is perfect. So at least I know the wire is good. I'm posting a couple more pictures as an FYI.

    Jack...I will not carefully try and remove the back cover of the ECM and report back. I will also post the JPPSG requirements....
