Open in Main Relay 2 Circuit

Cause of DTC

When any of the following is detected: 1. Relay contact is off (BS2 terminal is less than 3.5 V) for at least 0.2 sec. when R2+ terminal voltage is 9.0 V or more and main relay 2 is on. 2. R2+ terminal voltage is less than 9.0 V and main relay 2 cannot be on for at least 2 seconds when main relay 2 is turned on (BS1 terminal is 3.5 V or more). 3. With the main relays 1 and 2 ON and all solenoids and the motor relay 1 and 2 not activated, the BS2 terminal voltage is lower than BS1s by 2 V or more for 1 second or more. 4. With the solenoid OFF, the difference between BS1 and BS2 is 2 V or more for 2 seconds or more.
