Description The TIM supply voltage is too low (<16V). Effects on the driving operation No communication with the TIM possible. Unable to read the transmission-specific data. The vehicle might drive with the wrong transmission configuration. Possible causes The software version of the transmission control unit does not match the software version of the TIM. Internal fault in the transmission control unit. Internal fault in the TIM. Connector pin assignment of the transmission control unit

Internal cable harness Location ECU software, TIM. Instruction Ensure stable voltage supply. Clear fault memory. Setting conditions for the event No description available. Test conditions for the event No description available. Final function check If the defective component cannot be clearly identified, you should try to reproduce the fault: Reinstall the component in the vehicle. Test the function. After the fault has been eliminated, the following steps have to be carried out: Conduct a test drive with function check. Read out the fault memory. Check the transmission for leaks. Perform a final visual inspection. These steps are necessary to ensure the entire vehicle functions. See also:
