MAN All Fault Codes in PDF
A complete reference guide to MAN error codes (DTCs) for TGX, TGS, TGA, TGL, and TGM trucks. Quick explanations, troubleshooting instructions, and troubleshooting methods are available. Download the PDF guide for accurate diagnostics of EDC, EBS, FFR, ZBR, ECAM, and other systems. The most common terms and error codes, troubleshooting descriptions, and quick troubleshooting methods are included.
An essential resource for MAN mechanics.
MAN Air Conditioning Fault Codes
The Air Conditioning Fault Codes List includes codes related to the operation of the cabin heating, ventilation, and air conditioning (HVAC) system.
- Temperature Sensors
- Refrigerant Circuit Components
- Actuators and Air Controls
- Electrical Components and Power
MAN Electronic Diesel Control Fault Codes
A list of errors in the electronic diesel engine management system (EDC), which controls fuel injection, turbocharging, EGR, AdBlue, and DPF on MAN TGA/TGS/TGX/TGL/TGM trucks.
This system is called EDC (Electronic Diesel Control) and is based on Bosch/MAN ECUs (MS6.1, MS6.4, MS6.5, EDC7, EDC17), depending on the generation.
- Fuel injection (Common Rail or PDE),
- EGR (Exhaust Gas Recirculation) system,
- Turbocharging (VGT),
- Boost and fuel rail pressure,
- DPF (Diesel Particulate Filter),
- SCR/AdBlue,
- and ECU power supply.
MAN Electronically Controlled Air Suspension Fault Codes
This system is controlled by the ECAS ECU (manufactured by WABCO / Knorr-Bremse).
ECAS errors are recorded in the ECAS Control Unit and designated as Fault Codes,
which can be read from the instrument cluster or a diagnostic tool (MAN-cats, Jaltest, Texa).
MAN Zone Body Room (On-Board Computer Codes)
The central electronic body control module (Body Controller) on MAN TGA, TGS, TGX, TGM, and TGL trucks.
It can be considered the "brain" of the entire electrical system in the cab and chassis.
It controls:
- lights (headlights, parking lights, brake lights, turn signals, and courtesy lights),
- windshield wipers, mirrors, doors, power windows,
- heated mirrors, seats, and fuel filters,
- horns, and sound systems,
- and communicates with other units (EDC, EBS, ECAS, TCU, RET, HVAC, and instrument cluster) via the CAN bus.
