Trouble codes are displayed by the transmission sport mode warning lamp. u The TCM fault memory can also be checked using diagnostic equipment connected to the data link connector (DLC). Accessing - -07191 Ensure ignition switched OFF. Bridge data link connector (DLC) terminals A and C m. Switch ignition ON. Count transmission sport mode warning lamp flashes. Note trouble codes. Compare with trouble code table. Each trouble code consists of two groups of one or more flashes. The first group of flashes indicate the 'tens' of the trouble code [A]. The second group of flashes indicate the 'units' of the trouble code [Dl. A short pause separates each trouble code group rn [C]. A long pause separates each trouble code rn [El. For example: Trouble code 31 displayed rn. Each trouble code including 12 displayed three times Erasing - +07/91 Switch ignition OFF. Disconnect battery earth lead for 60 seconds. WARNING: Disconnecting battery may erase memory from electronic units (e.g. radio, clock). Repeat checking procedure to ensure no data remains in ECM fault memory. Accessing and erasing - 08/91 + The transmission control module (TCM) fault memory can only be accessed and erased using diagnostic equipment connected to the data link connector (DLC).
