MAN KSM Control Module Repair – Reliable Solutions for MAN Trucks

The MAN KSM Control Module (A2C85450700 / 81.25816.7008) is a key component in the electrical architecture of modern MAN trucks. It manages and distributes power to various subsystems, ensuring proper functionality of lights, wipers, central locking, communication buses, and other key electronic features. When this module fails, it can lead to widespread electrical malfunctions that disrupt vehicle operation and safety.

At Autolectronix, we provide professional repair and refurbishment services for MAN KSM (Kontrollsteuergerät Modul) units used in MAN TGA, TGS, TGX, and TGM series trucks. Our services help restore full functionality and reliability to your truck’s electrical systems at a fraction of the cost of a replacement unit.

🔧 Common Faults We Repair

• Power supply failures or blown internal components

• No communication via CAN line (no diagnostic link with PTM or FFR)

• Lights or indicators not functioning correctly

• Inoperative wipers, horn, or cab accessories

• Relay or output circuit failures

• Burnt PCB tracks or corrosion damage from moisture ingress

• Vehicle won’t start or intermittent power-up issues

These issues are commonly reported on MAN models fitted with the Continental KSM modules, particularly those used in harsh environments where moisture, vibration, and power surges can damage internal circuits.

⚙️ Supported MAN Truck Models

Our KSM module repair service supports the following models:

• MAN TGA (26.440, 33.480, 41.480, 41.540)

• MAN TGS (26.440, 26.480, 28.440, 33.480)

• MAN TGX (26.480, 28.540, 33.540, 41.540)

• MAN TGM (18.240, 18.290, 26.290)

These trucks commonly use 24V systems where the KSM module is responsible for body and chassis control, making proper operation essential for fleet reliability and safety.

🧠 Our Repair Process

1. Testing & Diagnostics – We run a complete bench test on the KSM to identify internal faults such as failed drivers, power regulators, or CAN communication breakdowns.

2. Component-Level Repair – Faulty transistors, relays, capacitors, and controllers are replaced with OEM-grade or superior components.

3. Reflow & Track Restoration – Damaged PCB traces or corroded joints are cleaned, reflowed, and resealed.

4. Final Verification – Each unit undergoes full load testing and CAN communication verification before dispatch.

5. Return & Installation Support – Once repaired, the module is returned ready to fit—no programming is normally required if refitted to the same truck.

🚛 Typical Symptoms of a Faulty KSM

• Dash lights flickering or failing

• Headlights or indicators stop working randomly

• No communication with diagnostic tools

• Truck cranks but will not start

• Electrical accessories losing power intermittently

• Fuse blowing repeatedly due to internal short circuits

These faults often point to internal damage in the KSM’s power management circuitry—something our technicians can reliably restore to full working order.
