Test requirements

The "Automatic Test Sequence" was carried
out and it was determined that the
Transmission Control Module (TCM) and
Engine Control Module (ECM) only contain
DTCs relating to ABS.

select the address word 00 with ignition
switched on;

- After completing electrical test, check and
erase DTC memories of Transmission Control
Module (TCM) and Engine Control Module
(ECM).
