STEP 3. Register the keyless ID using a known-good
transmitter of the same type again, and check the trouble
symptom.
(1) Register a known-good transmitter of the same type.
(2) Check if the signals from the transmitter switches are

received.

Q: Can the transmitter be registered correctly?

YES : Replace the original transmitter with a new one.
NO : Replace the WCM (Including when the new

transmitter cannot be registered). Replace WCM and
register the ID codes (Refer to

P.42C-114

). If the

transmitter works normally, the input signal from the
transmitter should be normal.
