Service bulletin 074900856

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

Altec used telematics data to identify JEMS in the field with batteries approaching critical discharge. After the min cell voltage becomes less than 3000mV the battery is no longer rechargeable in the field. To avoid costly battery replacement and decrease customer downtime, a letter describing the Battery Recovery Procedure from the manual was sent to the affected customers.
