I will try and figure out other things. What makes the J2534-2 protocol different from what I made?

I have another ECU I got from a scrap car to play with on bench going to see what I can do.

@T5-T6-Schnappi yes, it is a sniffer and a DOIP reader. My main aim when I started was to read info and faults from the car, I have lots of data now and an ongoing issue that I am hoping replacing the MAF will solve. Volvo original is over £400 GBP, I tried one cheaper off eBay and the values were higher than the faulty one.

I am consistently getting P0100 fault pending and turtle

I have a faulty - 2016 XC90 D5 - D4204T11 engine 2.0L four-cylinder twin-turbo diesel - Diagnostics Cable

I've made a cable that does both CAN and DOIP and written some software to interrogate the Volvo XC90 MK II D5 AWD, it is in early test but looking promising, and it runs on Ubuntu Linux.

My motivation for doing this is that my XC 90 that I owned from new has had some issues and is in Turtle / Tortoise mode with the only error P0100 Pending (MAF Malfunction)

I've recently fixed all leaks around oil pipes near turbo and had Exhaust Manifold gasket replaced because bolts came loose. It had a new Inlet Manifold under warranty at 97K Miles, and now at 140K has had Walnut Blasting, EGR Valve and Cooler replaced, Pressure Sensor Replaced.

My diagnostics is showing an imbalance of Block temp to thermostat temperature on cooling system which I think is main issue now, 1st I will bleed and top up system

If anyone knows what the DID codes represent below that would be very helpful.

• 0x40E2
  • 0x4311
  • 0x42ED
  • 0x42EE
  • 0x411D
  • 0x438B

Parts required for the cable -

510 Ohm Resistor
Female RJ45 Connector.
ODB2-Cable
CAN Adapter

Use a small straight through RJ45 cable 0.5m to your laptop.

Option 1 - ODB 2 to - Female RJ45
Pin 3 (RX+) - 1 - on the Female RJ45
Pin 11 (RX-) - 2
Pin 12 (TX+) 3
Pin 13 (TX-) - 6
The Resistor goes between pin 8 Activation and 16 is 12v this is needed to bring the IP live.

For the CAN - DSD TECH SH-C31G Isolated USB to CAN Adapter with FD Support Based on Canable 2.0 Pro

GND is Yellow and Orange ODB2 pins 4+5
CAN-H is Green - ODB2 - pin 6
CAN-L is Red/White - ODB2 - pin 14

IMPORTANT - Use a Multi-meter to check wires against pins, suppliers colours may change.

I was hoping I could program keys and maps with this set up but it seems Volvo locked it down and I need other things.

Will the cable I made work with VDASH for my 2016 SPA?

I've written basic software for Ubuntu Linux to diagnose the car, I record history of all feeds from cable every 1s then analyse.
