‹› The Engine Control Module (ECM) (J623) must remain connected for the following step.
-
Using a Multimeter, check the Transmission Control Module (TCM) (J217) electrical harness connector terminals 34 to 46 for resistance.
Specified value: 60 to 72 ohms (at approx. 20° C)
If the specified value was not obtained:
-
Check the wiring connection for an open circuit, short circuit to Battery (+) or Ground (GND).
-
Check the wiring connection for damage, corrosion, loose or broken terminals.
-
If necessary, repair the faulty wiring connection.
