In registration mode, insert the door control transmitter assembly into the ignition key cylinder and check the combination meter assembly (security indicator light).
If the new key ID code registration fails, code 2-1 will be output through the security light. Trying to re-register an already registered door control transmitter assembly will cause code 2-2 to be output when the door control transmitter assembly is inserted. If the number of registered key ID codes exceeds the maximum limit, code 2-3 will be output through the combination meter assembly (security indicator light). The output details are shown in the following illustration.
| *a | Combination Meter Assembly (Security Indicator Light) | *b | Normal (Immobiliser system is operating normally) |
| *c | Code 2-1 | *d | Code 2-2 |
| *e | Code 2-3 | - | - |
