I have a 2004 Prius with 120,000 miles. Engine light came on. Code reader indicates 'Control Module' $7EA and $7EB. Has anyone seen these codes and know what they mean? Any help would be appreciated... Thx
Those DTC apparently are corrupted as they lack the correct format. A correct DTC will have an LNNNN format, where: L = P for powertrain, C for chassis, B for body, U for communications, as examples N = a hexadecimal character; 0-9, A-F are acceptable values
Those are typically ECU addresses...... 7EA and 7EB are response addresses HVECU and the Traction Battery // ECUs // -- request/response // -- 7E0/7E8 for ECM (engine control module); // -- 7E1/7E9 for TCM (transmission control module). // -- 7E2/7EA for HVECU (Hybrid contol module) // -- 7E3/7EB for Traction Battery // -- 7E4/7EC // -- 7E5/7ED // -- 7E6/7EE // -- 7E7/7EF
