ABS DTC's

[kane67]

Hi All,

Started to get ABS DTC's unfrequently, it shows codes 42,43, 52 and once 65. They all seem to be BPMV codes (control valves), so my question is... is there anything what I can do or only fix would be to change the unit?

Also tried to clear ABS DTC's like manual says, H pin grounded with A (2sec on / 1sec off / 2sec on) with no luck...

Would brake fluid effect somehow badly to control valves?

Sub's been in Texas first 10 years, then CA til it was imported to Finland Feb/07 :)

DTC 42 - Fuel Temperature Circuit Low (High Temp Indicated)

DTC 43 - Fuel Temperature Circuit High (Low Temp Indicated)

*DTC 52 - System Voltage High Long

DTC 65 - Accelerator Pedal Position 3 Circuit Range Fault

NOTE: All DTC(S) with the * sign are automatic transmission (4L80E) related


There is NO ABS codes of them, you noted.

Try to remove the battery cables for about half an hour or over night, than the codes are definitly cleared. Drive again and until the fist time the SES light comes on again, check for codes. How to ? Look here :
How to read DTC codes (http://www.kennedydiesel.com/readcodes.html)

Post them again here and than we will see.

Hi Sven,

As Service manual says, you connect pins H and A to get ABS dtc's out.
"Normal" dtc's are read by connecting pins A and B.
