Checking Signal Cable
- Connect the test box and check ground terminals.

- The ohmmeter should read 0 - 3 k ohms.

If reading is OK:
^ Check cable between engine control module (ECM) # B26 and transmission control module (TCM) # B15 for a short-circuit to supply voltage.

If reading is incorrect:
^ Check cable between engine control module # B26 and transmission control module # B15 for a short-circuit to supply voltage.
