EC-990 [YD (WITH EURO-OBD)] TROUBLE DIAGNOSIS : Average voltage for pulse signal (Actual pulse signal can be confirmed by oscilloscope.) *1: For YD22DDT engine models CONSULT-II Function EBS0138F FUNCTION *: The following emission-related diagnostic information is cleared when the ECM memory is erased. ● Diagnostic trouble codes ● 1st/2nd trip diagnostic trouble codes ● Freeze frame data 111 R/B Power steering pressure [Engine is running] ● Steering wheel is being turned Approximately 0V [Engine is running] ● Steering wheel is not being turned BATTERY VOLTAGE 113 G ECM relay (self-shutoff) [Ignition switch ON] ● For a few seconds after turning ignition Approximately 1.2V [Ignition switch OFF] ● More than a few seconds after turning BATTERY VOLTAGE 114 B ECM ground [Engine is running] ● Idle speed Approximately 0V 119 120 R Power supply for ECM [Ignition switch ON] BATTERY VOLTAGE 121 W/L Power supply for ECM [Ignition switch OFF] BATTERY VOLTAGE TERMI- NAL NO. WIRE COLOR ITEM CONDITION DATA (DC Voltage and Pulse Signal) Diagnostic test mode Function Self-diagnostic results Self-diagnostic results such as 1st/2nd trip DTC, DTC and freeze frame data can be read and erased Data monitor Input/Output data in the ECM can be read. Active test Diagnostic Test Mode in which CONSULT-II drives some actuators apart from the ECMs and also Function test This mode is used to inform customers when their vehicle condition requires periodic maintenance. ECM part number ECM part number can be read. |
