    Thanks in advance for your answers & advice. Everyone here has been great.

    So, while driving my G2 base, the gas motor shut off right after rounding a corner and the dreaded red triangle came on (along with most if not all the other dash lights). The traction motor stayed on long enough for me to make a U-turn back towards home. But shortly afterwards when I stopped at a red light, no more love, the car bumped itself to neutral, AC shut down, and an hour later AAA brought me and the G2 back home.

    • My battery was just under 3 years old and didn't pass a load test. Lucky for me the replacement warranty wasn't pro-rated. Thank you Walmart.
    • The AM2 fuse is OK fine
    • Inverter pump coolant flow looks very weak (ie: peering in the reservoir, the coolant is barely moving). The pump was replaced about 8 years ago so I'm having a new Toyota 04000-32528 and some SLLC2 shipped to me.
    • Using my ThinkDiag2, the primary Fault code is a P0A94. There's also a few SRS codes (B1826, B1650, B1653, B1655, B1821, & B1826), an Occupant Detection code (B1771 which may be the root of the SRS issues), and two AC codes (B1421 & B1442).
    So here are a few questions. Since the biggest concern is the P0A94, I can't for the life of me figure out how to get my ThinkDiag2 to display the P0A94 subcode. Is that beyond the capacities of this scanner? If you happen to know that it's not, could you share the steps to get them to display?

    So when the think diag maybe going to the freeze frame data and see if offers Alt code .

    You're only supposed to see the coolant barely moving in inverter resvoir. Normal

    So the big question now is what's voltage on 12V sitting they're off ? And the minute you ready the car it should read 14 Volt you should see the change on voltmeter instantly 13.4 and less no good

    It sits just below 13v after a trickle charge on a brand new battery

    While it's ready I'm talking. So you walk up to the car in the morning you test standing should be above 12.4 AGM. Then you ready the car and it should jump to 14V . ????? ?. If that's not the case you may be looking at the DC to DC converter

    P0A94 shows as "DC - DC converter performance". Since there are over two dozen sub codes, you really need the additional information to figure out where the problem is.

    As mentioned, go into freezeframe data for the code, and scroll through it. Somewhere should be several lines labeled "INF" or "detail". Most will have 000, but one should have other numbers - the sub code.
