AAM Product Lines We Repair
Our engineers are trained on the full AAM product range. Below are the major product families we service.
Integrated Motor Control (IMC) Modules
AAM's real-time motor control electronics for electric drivetrain systems and hybrid commercial vehicles. Common failures include firmware corruption, phase-leg driver burnout, and resolver signal loss affecting torque vectoring and regenerative braking performance.
Electronic Differential Lock (eDL) Controllers
Adaptive locking controllers for commercial vehicle axles, managing wheel slip and traction in off-road and adverse terrain conditions. Typical faults: solenoid drive circuit failure, CAN transceiver dropout, and wheel speed sensor interface corruption.
Steering Control & Safety Interface (SCSI) Boards
Real-time steering angle and torque feedback modules for electronic power steering integration and collision-avoidance systems. Repair issues include steering sensor signal processing errors, redundancy channel misalignment, and watchdog timer resets.
Power Distribution Modules (PDM) for EV Drivetrains
High-current switching and monitoring boards for battery management and multi-motor coordination in electric commercial vehicles. Common failures: MOSFET gate drive failure, current sense IC malfunction, and over-temperature latch faults.
Transmission Interface Relay Units (TIRU)
Communication gateways bridging transmission ECU and chassis CAN networks in integrated powertrain systems. Faults include isolation barrier IC breakdown, ESD damage to signal conditioning circuits, and firmware version mismatch errors.

Common AAM Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in AAM equipment arriving at our workshop.
- ✓Firmware Corruption in IMC Motor Control Modules — AAM's IMC modules store real-time commutation tables in flash memory. Voltage spikes during heavy regenerative braking or incorrect battery polarity can corrupt the bootloader, preventing safe restart of motor control loops.
- ✓Electronic Differential Lock Solenoid Driver Burnout — AAM's eDL controllers use high-frequency PWM (8–12 kHz) to energize locking solenoids. Coil inductance spikes and reverse-polarity transients from rough terrain conditions repeatedly stress the driver MOSFET, leading to gate-oxide breakdown.
- ✓Wheel Speed Sensor Signal Loss in eDL Feedback Chain — AAM's eDL modules read magnetoresistive wheel sensors via 400 mV amplitude differential signals. Mud ingress, corrosion on connector pins, or noise coupling from adjacent high-current harnesses cause signal dropout, disabling traction control.
- ✓Steering Control SCSI Board Sensor Fusion Drift — AAM's redundant steering angle sensors (resolver + potentiometer) require synchronized calibration during power-up. Connector corrosion or thermal stress misaligns sensor offsets, causing heading-estimate divergence and collision-avoidance system nuisance faults.
- ✓Power Distribution Module MOSFET Gate Drive Failure — AAM's PDM-EV high-current modules drive 600A+ through parallel MOSFET arrays. Bootstrap capacitor ESR rise or gate-resistor erosion reduces drive current, creating shoot-through risk and catastrophic thermal runaway during rapid load transients.
- ✓Transmission Interface Relay (TIRU) CAN Transceiver Short to Ground — AAM's TIRU modules isolate transmission ECU from chassis CAN via TI or Infineon isolated transceivers. Moisture ingress or vibration-induced crack in substrate can short the transceiver supply rail, silencing all transmission feedback and preventing gear selection.

Frequently Asked Questions — AAM Repairs
Do you repair AAM equipment anywhere in India?+
Yes. Synchronics repairs the full AAM drivetrain electronics portfolio — motor control modules, differential lock controllers, steering interface boards, and power distribution units. We offer same-day PAN India door pickup from Mumbai, Delhi, Bangalore, Pune, Chennai, Hyderabad, Ahmedabad, and Kolkata. All repairs are processed in our certified facility in Vadodara, Gujarat, with TAT typically 5–7 working days.
Can Synchronics reprogram AAM firmware and restore lost calibration data?+
Yes, absolutely. AAM's IMC, eDL, and SCSI modules store vehicle-specific calibration in non-volatile flash. Synchronics uses JTAG and secure-boot protocols to read out your existing calibration before repair, or we can re-flash factory baseline firmware and re-tune parameters like motor commutation, solenoid dwell, and steering sensor offsets using your original bill of materials (BOM).
What is your warranty on AAM drivetrain electronics repairs?+
Synchronics offers 24 months parts and labour warranty on all AAM repairs, valid across India. We use OEM-equivalent components (TI, Infineon, Allegro semiconductors) and perform 100-hour runtime validation before dispatch. If a repaired AAM module fails within warranty, we replace it free of charge — no downtime, no questions.
Do you stock AAM modules or do repairs only?+
Synchronics specializes in deep repair and component-level restoration of AAM modules. While we do not stock new AAM units (as these are typically direct-order from AAM or OEM channels), we maintain an active inventory of spare semiconductor dies, capacitors, and interconnect assemblies. This allows us to repair modules that would otherwise be scrapped, saving you 60–75% versus new unit cost.
Can you help with AAM fault code diagnosis and CAN network troubleshooting?+
Yes. Synchronics engineers use oscilloscopes, CAN protocol analyzers, and AAM's proprietary diagnostic software to isolate faults in complex drivetrain systems. Common issues we diagnose: CAN signal dropout, sensor signal conditioning errors, and watchdog timer faults. We provide a detailed fault report with root-cause analysis and recommend preventive actions (e.g., connector sealing, harness shielding) to avoid repeat failures.
How do I send my AAM unit for repair?+
Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.
What is the cost of repairing a AAM drive or PLC?+
Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.
What warranty do you provide on AAM repairs?+
All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your AAM unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
