Ignition Relay Malfunction Detection Function
WARNING: This page is about a different variant/trim than selected.
- IPDM E/R monitors the voltage at the contact circuit and excitation coil circuit of the ignition relay-1 inside it.
- IPDM E/R judges the ignition relay-1 error if the voltage differs between the contact circuit and the excitation coil circuit.
- If the ignition relay-1 cannot turn OFF due to contact seizure, it activates the tail lamp relay for 10 minutes to alert the user to the ignition relay-1 malfunction when the ignition switch is turned OFF.
| DTC | Ignition switch | Ignition relay | Tail lamp relay |
|---|---|---|---|
| - | ON | ON | - |
| - | OFF | OFF | - |
| B2098: IGN RELAY ON | OFF | ON | ON (10 minutes) |
| B2099: IGN RELAY OFF | ON | OFF | - |
NOTE:
The tail lamp turns OFF when the ignition switch is turned ON.
FRONT WIPER CONTROL
IPDM E/R detects front wiper stop position by a front wiper auto stop signal.
When a front wiper auto stop signal is in the conditions listed below, IPDM E/R stops power supply to wiper after repeating a front wiper 10 seconds activation and 20 seconds stop five times.
| Ignition switch | Front wiper switch | Auto stop signal |
|---|---|---|
| ON | OFF | Front wiper stop position signal cannot be input 10 seconds. |
| ON | The signal does not change for 10 seconds. |
NOTE:
This operation status can be confirmed on the IPDM E/R "Data Monitor" that displays "BLOCK" for the item "WIP PROT" while the wiper is stopped.
