ELECTRICAL 26 Sr No DTC No Code Description Probable causes Rectification/Repair actions 3 U3006 - 17 Control Module Input Power "A" - circuit voltage above threshold 1) Fuses in Fuse box 2) Battery Supply line 3) Alternator overcharging 1) Check wiring Connections & connectors of power supply if damaged than Replace the vehicle wiring harness or connector. 2) Measure supply voltage (> 11.5 V) at ECU power supply connector from wiring harness side if voltage is > 16V than check the battery if required replace/repair the battery. 3)Check resistance between vehicle ground and ground at the power supply connector(should be <1 ohm) if resistance did not meet the requirement check the wiring connection and if problem still persist than replace the wiring harness. 4) Check the fuses in Fuse box (J- Case Fuse (60 Amp)) if fuse is blown than replace a fuse. 5) Check the power supply line for short circuit if persist change the wiring harness. 6) Check alternator voltage (13.5 V to 14.5 V in engine running condition) if output is not correct than repair / replace the alternator. 4 U1006 - 42 Control Module Internal - general memory failure 1) Internal ECU failure. 1) Reset the ECU. Remove the power supply plug connector from ECU and reconnect after about 5 minutes. If DTC are still persists than replace the ECU. 5 U1006 - 4B Control Module Internal - over temperature 1) Internal ECU failure. 1) Reset the ECU. Remove the power supply plug connector from ECU and reconnect after about 5 minutes. If DTC are still persists than replace the ECU. 6 U1006 - 04 Control Module Internal - System Internal Failures 1) Internal ECU failure. 1) Reset the ECU. Remove the power supply plug connector from ECU and reconnect after about 5 minutes. 2) Or Reflash EPAS ECU. Reset the ECU. Remove the power plug from ECU and reconnect after about 5 minutes. If DTC are still persist than replace the ECU. 7 U1006 - 49 Control Module Internal - internal electronic failure 1) Internal ECU failure. 1) Reset the ECU. Remove the power plug from ECU and reconnect after about 5 minutes. If DTC are still persist than replace the ECU. 8 P0602 - 54 Control Module Programming Error - missing calibration 1) Tuning file (calibration software for variant specific) missing in EPAS ECU 1) Check for calibration file mismatch /Re-flash the ECU with the correct calibration file version.
