Frequently Asked Questions
How long does the GREATWALL 044200502S service take?
Standard turnaround is same-day or next working day once we receive your module. Express service prioritizes your module for same-day processing and return shipping.
Will this fix my fault codes?
If fault codes are stored in the module memory due to software/memory issues, yes. However, if there are physical component faults (sensors, wiring, actuators), those must be repaired separately before the module will function correctly.
Can I reset the module myself with a scan tool?
Standard diagnostic scan tools can clear active fault codes, but cannot address deeper memory errors, corruption, or programming issues that affect BATTERY modules. Professional bench service with specialized equipment is required for proper module reset.
Do you need my vehicle or just the module?
Just the BATTERY module. This is a postal service - you remove the module from your vehicle (see workshop manual for location), send it to us, and we return it serviced and ready to reinstall.
