Hello, my GLE was left in my garage for an extended period and I had to replace both aux and main batteries. Then these messages came up when I scanned

Left fron reversible emergency tensioning retractor U040100 - Implausible data was received from control unit 'combustible engine'

Right fron reversible emergency tensioning retractor U040100 - Implausible data was received from control unit 'combustible engine'

How do I resolve this?

Possible Causes:

• Issues with Power Source (Alternator Charging or Battery)
• Check ECM/PCM/ECU fuses
• Wiring Harness Open or Short (Check Connections)
• ECM/PCM Module has bad ground
• Faulty ECM/PCM

What vehicles is this for?

I had this code back in 2019 and the dealer replace the main battery due to low voltage. - I see you replace the main and Aux battery.
