WIRELESS CONTROL MODULE (WCM)

42C-113

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.
