P300E-1D Pressure control solenoid 5 (EDS 5) line pressure current deviation: current target not reached Overview: ISO Code P300E-1D Customer Symptom • Critical malfunction. Powertrain is opened. Power loss immediately triggered. Gearshift is disabled. • Transmission fault lamp ON • Creep function is disabled Fault Effects (On Vehicle) • Critical malfunction. Powertrain is opened. Power loss immediately triggered. Gearshift is disabled. • Transmission fault lamp ON • Creep function is disabled Lamp Status (If Any) Transmission fault lamp ON (Service indication 0x1) Fault Detection Condition solenoid current target not reached (FFT = 5000ms) Normal Operating Condition TCU does not detect any fault Probable Trouble Area 1. Battery voltage (VBAT_Value_mV) and current target (osc_I_clu2ActrTgt). 2. TCU. 3. HCU. Healing Condition The reaction is cleared at SW restart if the detection is FALSE for more than 0 ms Component Details: The Clutch actuator 1 & 2 mounted in hydraulic control unit and makes internal electrical contact with the TCU. • EDS 5 = Line pressure solenoid Preliminary Checks: 1) Loose/ Damaged Connections between Solenoid and TCU. 2) Loose/ Damaged mechanical fitments of TCU (TCU to valve body mounting). 3) Check correct fitment of ground cable connections on vehicle chassis. Trouble Shooting:- Step Checks IF YES IF NO 1 Check battery voltage (VBAT_Value_mV) and current target (osc_I_clu2ActrTgt) versus measured current (cin_I_clu2Meas) in freezeframe. If battery voltage below 8V, check battery/power supply/connectors to TCU/Cable harness Go to step 2 2 Replace the TCU if the problem persists & flash the adaption data from the previous TCU. Clear the DTC and check if the DTC does not come back. Go to step 3 3 Replace the HCU if the problem persists & flash the adaption data from the previous TCU. Clear the DTC and check if the DTC does not come back.
