Displaying and Reading Trouble Codes

DIAGNOSTIC TROUBLE CODES (DTC)






1. DTC can be displayed by the Transmission Control Module (TCM) by shorting together terminals 1 and 2 of the TCM Diagnosis Connector (C-92) located right side of left front foot well (This grounds the TCM pin D16).






2. After this, the CHECK TRANS Indicator will be OFF for 3.2 second and then will flash each DTC 3 times.

- When there are more than 9 flashes this means that the indicator is constantly flashing, OFF for 0.4 seconds, ON for 0.4 seconds. In this case there is no DTC stored in memory.

- To find the problem without a scan tool and without DTC GOTO WITHOUT DTC CHECK.

- When there are less than 9 flashes you will see DTC of 2 digits repeated 3 times each and when all codes have been displayed they are displayed again beginning from the first one.

- Do not care about the DTC order if "21" is before "22" it does not matter.

- Write down all codes numbers and GOTO DTC CHECK.

3. IF CHECK TRANS indicator is not flashing GOTO "CHECK TRANS" CHECK.
