DTC 00529 / P0727 for vehicles with CAN-Bus A)





1) Pay attention to which hydraulic control the transmission has when selecting measuring value block.
A) There is a difference between vehicle with and without CAN-bus.

Note for DTC 00529 / P0727 for vehicles with CAN-Bus:

^ The engine speed signal is transmitted by the Engine Control Module (ECM) to the Transmission Control Module (TCM) via the CAN-bus wiring.
^ Requirements for malfunction recognition: Malfunction of the relevant component is recognized by the Engine Control Module. This diagnostic is transmitted to the Transmission Control Module (TCM) via the CAN-bus wiring.

1) One of these indications is also displayed for the relevant component.
2) Pay attention to which hydraulic control the transmission has when selecting measuring value block.
A) There is a difference between vehicles with and without CAN-bus.

Note for DTC 00529 / P0727 for vehicle types without CAN-Bus A):

^ Malfunction recognition of DTC 00529 / PO727 by the TCM is much more sensitive than detection by the ECM. This means that a brief interruption in the throttle position signal (up to 1 second) is not detected by the ECM, but is registered as a malfunction by the TCM.
^ Malfunction detection for DTC 00529 / PO727 is based on a plausibility test relating the signal to the fuel consumption signal (or if not installed to throttle position value).
^ Requirements for malfunction recognition- Multi-function TR switch -F125- OK, fuel consumption signal or throttle position signal OK, recognized value for transmission RPM above 200 RPM and 200 ms no engine RPM signal at Transmission Control Module (TCM).
