Directory coverage

Code descriptions help explain the diagnostic process. Interpretation depends on the full fault text, suffix, reporting controller and software version. The same base code can refer to different situations. This is not a parts-replacement instruction or a complete list for every version.

Fault codes

P086700Transmission pressure: operation restricted by a pressure drop

Code details: P086700 / 30097
What is checked?: Requested and actual pressure are compared, with checks of fluid supply, pump operation and possible leakage. Temperature and load when the fault occurs help narrow down the cause.
