Procedure |
Refer to |
---|---|---|---|
Registering additional electrical key transmitter sub-assembly |
Customer must bring at least 1 electrical key transmitter sub-assembly |
1. Register additional electrical key transmitter sub-assemblies as necessary (additional key ID registration) |
PROCEDURE "C" |
NOTICE: If the customer brings at least 1 electrical key transmitter sub-assembly, it is possible to perform these procedures. However, if any additional electrical key transmitter sub-assemblies are registered before reregistering the customer's electrical key transmitter sub-assemblies, the customer's electrical key transmitter sub-assemblies cannot be reregistered and become useless. Therefore, if the customer does not bring all of their electrical key transmitter sub-assemblies, be sure to explain to them that any electrical key transmitter sub-assemblies not brought will become useless after additional electrical key transmitter sub-assemblies are registered. HINT: After electrical key transmitter sub-assembly ID erasure, any remaining electrical key transmitter sub-assemblies that are not reregistered at this time cannot be used. Therefore, immediately after electrical key transmitter sub-assembly ID erasure, be sure to reregister all available remaining electrical key transmitter sub-assemblies. |
Customer must bring at least 1 electrical key transmitter sub-assembly |
1. Using remaining electrical key transmitter sub-assembly, clear all registered electrical key transmitter sub-assemblies except one (key ID erasure) |
