Troubleshooting - General Information

When a fault is detected automatic transmission, first check the level of ATF (see chap. Current care and maintenance). If the level is not enough, reassess the appropriate seals. Carefully inspect all hoses tract ATF, as well as heat transmission fluid cooler and check for signs of leakage. The only thing that can still be done by the owner of the vehicle, is to check / replace the sensor information management system AT. Before proceeding to replace the suspect sensor, make a survey of the memory control module (TCM), - all of any significant faults recorded in the memory module in the form of codes DTC (see the code list. In the Specifications Chapter Automatic Transmission).

In the case of particularly serious violations of TCM transmission automatically switches to the emergency mode of operation.

Read the DTC is made using a special scanner connects to the system board self-test (DTC) (see. Section Read the DTC, clear the memory of the processor), - in the absence of access to the necessary equipment will be enough to try at least qualitatively determine the nature of the fault (at the level of : electrical / mechanical) in order to facilitate communication with the service specialist. It should not be premature to proceed to the removal of antibodies as diagnostic it seems possible only in the prescribed position.
