Specified value: 1.5 Ohms Max.

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, lose or broken terminals.

-

If necessary, repair the faulty wiring connection.

If no malfunction is found in the wiring:

-

Replace the Mechatronic unit in the transmission.

Final procedures

After the repair work, the following work steps must be performed in the following sequence:

1. Check the DTC memory.
2. If necessary, erase the DTC memory.
3. If the DTC memory was erased, generate readiness code.

-

End of diagnosis.
