The FRM (Footwell Module) controls multiple body and comfort functions, including:
-
Exterior and interior lights

Common FRM failure symptoms
If the FRM becomes corrupted or blocked, you may experience one or more of the following:

❌ Electric mirrors inoperative
❌ No communication with the FRM on diagnostics
❌ Multiple lighting or body control fault codes

Common causes of FRM failure
In most cases, the FRM is not physically damaged, but the internal memory becomes corrupted due to:
🔋 Completely flat or weak battery

⚡ Incorrect jump starting
💻 Interrupted coding or software update
🚗 Vehicle standing unused for a long period
