Sound to me like the ECU is doing what it's suppose to do. Open Loop.

Check O2S heater circuit for continuity. Looking for ≈5-7 Ω's.

With that O2 and maybe that Coolant sensor, it can't go into Closed Loop.

O2 (V) seems frozen at idle. Should switch rapidly between 0.5 and 4.5. Rapidly like at the speed of light. Coolant sensor is trashed, or wire is your problem.

O2S with slow response time. O2 is a maintenance item.

Should read the solenoids if all testing was done on the same side of the connector. Tough call here. Seems to be the next step. Best you can do here is check for voltage at the TCU. C234_D14 - Hot at all times - (D1_5) C234_D16 - IGN SW Run/Start - (D2_4)

The question here is do male pins go to Transmission or do they go to Engine Control Harness. I can't tell from the photos, but one side goes down to the trans. I think you're talking about the male pin side of the connector. If true, this side goes to the Engine Control Harness. More Info: _mj1988electricalmanual_1.pdf

No, I don't. Maybe someone here onsite has one or at the JY.

Looks like C263 Resistor Pack (missing). Don't understand why wiring was hacked into but seems correct, unless there's more wiring higher up the harness. Couple of more views.

Seems like wires were not cut, but "T spliced" in to. Post ENG?/YR? info. Need to narrow this wiring down some. Can you determine TCU pin letter/numbers?

Check B+ Latch Relay. Used for resetting the ISA at ENGINE OFF. Use a known good relay or swap your relays around with one another. See if problems follow relay.

Do you offer AAA Road Service?

What a hunk of Chunk. Looking good.

I concur "location in the vehicle isn't strictly critical knowledge to the bleeding process.", but I wonder about whoever authored this procedure, is there anything else that could be in question.

Procedure states “Essentially, the pressure differential valve (inside the combo valve) must be moved to a full forward position”, but isn’t it shifted to full rear position, for complete bleeding of rear brake height sensing valve and both rear brake feed circuits. Maybe I’m just looking at the pictures wrong. @Eagle

a.k.a. Data Link Connector (DLC) defined by SAE J1962.

Do you let her drive them? Maybe you should, it could help with keeping them.

I believe that one day you will drive again because I think that's just who you are.

Welcome to CC Forum.

Check this fuse.

Disconnect CTS. Reconnect your DVOM across CTS. Measure Ω’s with COLD engine. As engine HEATS up, look for Ω values to decrease. Once engine reaches Normal Operating temperature, DVOM should show less than 1000 Ω’s.
