P2713-19 Pressure control solenoid 4 (EDS 4) clutch 1 cooling: over current Overview: ISO Code P2713-19 Customer Symptom • Transmission fault lamp ON • Clutch 1 Deactivated, only limited gears available Fault Effects (On Vehicle) • Transmission fault lamp ON • Clutch 1 Deactivated, only limited gears available Lamp Status (If Any) Transmission fault lamp ON Service indication 0x2 Fault Detection Condition Internal TCU error >1000ms. Normal Operating Condition TCU does not detect any fault. Probable Trouble Area 1. Transmission wiring loom for any damage. 2. TCU. 3. Hydraulic unit & transmission oil. Healing Condition The reaction is cleared at SW restart and driving if the detection is FALSE for more than 2000 ms. Component Details: Clutch actuator 1 & 2 mounted in hydraulic control unit and makes internal electrical contact with the TCU. • EDS 4 = Clutch 1 (“Brake”) cooling flow 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 the transmission wiring loom for any damage. If damaged, replace the wiring loom. 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 If DTC persists, place back original TCU, and replace the hydraulic unit & transmission oil. Perform all necessary transmission adaptions. Clear the DTC and check if the DTC does not come back. • Resistance Check Solenoids, Pressure sensors mounted on HCU should be checked for resistance if there is DTC triggered. Below table reflects the signals for each solenoid and pressure sensor and range of acceptable resistance.
