    2013 Hino 195 P20B2

    So for both cabovers and conventional trucks, when the def tank temp comes up, the coolant shutoff valve closes. If the temp continues to rise it's interpreted as the valve is stuck open. While this does happen occasionally, the def tank sending unit is usually the culprit. There's currently a...

    2007 JO8E-tv . Reprogramming?

    At times like this you must divorce the supply side of the fuel system from the high pressure side. After making sure nothing is blocking the pump inlet, plumb in an auxiliary fuel source. I use a boat gas tank. Then go for a test drive. Wide open throttle for as long as you can, with a computer...

    Hino 268 No Brake Lights

    Good eye. Many of these relays are common to Toyotas so you can probably get them at Napa. I think the denso part numbers will cross.

    2006 hino 268 fuel not equalizing passenger tank running empty!

    It sounds like maybe there's something clogging the left tank if it's not pulling fuel from it. Does your 2006 still have its original steel tanks? Those like to rust inside and rusty chunks get caught up in the elbows on the tops of the tank and sometimes the tank pickup tubes. I'd have a good...

    Hino 268 No Brake Lights

    The valve mounted switch you're after has a black and a white/black wire. It grounds the control side of the stop lamp relay. Inspect the connector and several inches of its wire for corrosion and cracked insulation. I've seen both. The stop/turn controller ultimately turns on the brake lights...

    2007 JO8E-tv . Reprogramming?

    These fuel systems are similar to the Duramax. This era of Hino is prone to getting debris stuck in the fuel supply system. The right angle fittings in the tank, rust chunks at the bottom of the tank, and the banjo fitting in the fuel filter are all common places for debris to clog. This can be...

    Runaway RPM

    There's also a connector in the junction box that has all the accelerator wires going through it. I've seen that cause unintended acceleration.

    Moisture and corrosion forms on the CAN lines in the junction box if water gets in there. If the CAN is good, it most likely needs a TCM. I've also seen Samsara elds cause communication errors and weird shifting.

    1998 HINO SG3320 Flickering Battery light when driving with emergency lights

    This sounds a lot like a bad ground. Idk where the grounds are on that, but on many of these Japanese trucks many of the cab and light grounds are at the very front of the left frame rail.

    Hino 268 crank no start

    I've never seen a bad Hino ECU. It's possible, but more likely it's something else. I'm not super familiar with UD wiring, but many of these Japanese trucks feature a box full of connectors that fill with water. Id look at those areas first.
