- 04 VY L63
G'day,
My 04 VY has recently started having computer issues. Everytime the car hits 82 degrees (I have an aftermarket engine guard which just reads temp of engine) the ABS fault warning, check engine, and service error - contact retailer warnings come on. As well as this I lose the gear selector icons in the dash, the dash temp gauge stops working, the a/c stops working, and the car idles just above stall (>500rpm). If I continue to drive for a bit this all resets and the car goes back to normal. I went and got the codes read and here's what it's reading:
BCM:
- 18 Auxiliary Serial Data Bus Fault
-02 Slip Ring Failure
-07 PCM data lost
-26 ABS data lost
ECM:
-P0506 Idle Speed Error
-P1255 Theft Deterrent Signal Missing (This could be because I have an aftermarket display instead of the stock radio)
-P0131 Right Hand Oxygen Sensor Signal Voltage Low
-P1064 Low Speed Fan No BCM Response
-P0530 A/C Refrigerant Pressure Sensor Circuit Malfunction
-P1571 Requested Torque Outputs Of Range
Instrument:
-18 ECC fault logged
Some things that could be noteworthy:
New Battery, second hand alternator (already ordered another one this is just a placeholder), Lpg, After codes were cleared did try removing temp monitor (engine guard) and still occurred.
Engine Guard is this:

Any help is appreciated as this is my first car with computers
