# Service bulletin A19\-071

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.

- Type: Service bulletin
- NHTSA id: 10162451
- Published by NHTSA: 2019\-07\-11
- Manufacturer's number: A19\-071
- Manufacturer's date: 2019\-07\-05
- NHTSA component: VEHICLE SPEED CONTROL; ELECTRICAL SYSTEM:12V/24V/48V BATTERY; POWER TRAIN; POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE \(TCM/PCM/TECM\)

## NHTSA's summary

Service Bulletin \- Auto idle stop does not work. The PCM incorrectly calculates battery current, which prevents auto idle stop from working.
