Press P4 and / or P5a. If L1 and/or L2 gives light, exchange lamp in P0b. If L1 and/or L2 doesn’t give light, check power source including fuses. See Wiringdiagram in Operator’s manual 12155016.2. Check L10 and L11a. If L10 and L11 doesn’t give light, connect connector C1 directly to C2. If then L10 andL11 gives light, exchange CANBUS cable.b. Disconnect seven-pole connector for loaderc. If L10 and L11 doesn’t give light, exchange control box. If that doesn’t help, see d.d. If L10 and L11 doesn’t give light, exchange joystick.Symptom B No function for boom and bucket1.
