DTC DETECTING CONDITION CHART

Item Detecting Condition Possible cause
DTC strategy
  • Voltage monitoring
  • Open or short in power supply circuit (IGN+)
Case 1 Monitoring Period
  • Once during startup.
Enable Conditions
  • Watchdog and valve relay function is tested during startup.A failure is detected if the valve relay/Enable remains in off position when it is turned on and vice versa. Reason could be short to GND or UZ, interrupted lines or a inoperative output stage etc.
Case 2 Monitoring Period
  • Continuous
Enable Conditions
  • A Fault is detected if valve relay voltage < 0.8 * battery voltage for a time 500 ms.
Case 3 Monitoring Period
  • Continuous
Enable Conditions
  • If valve relay malfunction and supply solenoid valve short to battery or supply solenoid valve and medium or high ohmic short of valve relay (or a valve) to valve relay voltage, solenoid valve voltage or GND are detected.
