Ignition Relay Malfunction Detection Function
- IPDM E/R monitors the voltage at the contact circuit and excitation coil circuit of the ignition relay inside it.
- IPDM E/R judges the ignition relay error if the voltage differs between the contact circuit and the excitation coil circuit.
- If the ignition relay cannot turn OFF due to contact seizure, it activates the tail lamp relay for 10 minutes to alert the user to the ignition relay malfunction when the ignition switch is turned OFF.
| Ignition switch | Ignition relay | Tail lamp relay |
|---|---|---|
| ON | ON | - |
| OFF | OFF | - |
NOTE:
The tail lamp turns OFF when the ignition switch is turned ON.
