Faulty Signal

Faulty signal

Checking programming
If the fault is intermittent, it has been registered previously but is no longer present. Intermittent faults can be caused by interference at start up of the central electronic module (CEM) or may be a different type of fault which occurs on different occasions. The fault is evaluated depending on how it occurs.

Note! The diagnostic trouble code (DTC) is stored if the central electronic module (CEM) registers that the software in the transmission control module (TCM) is faulty or modified. It is therefore important that no steps are taken to remedy modified software in the transmission control module (TCM) without first consulting the customer. Neither may software be remedied if the software has been modified by the customer, but this is not the reason for the repair work.
