Service bulletin PS448

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

PITSTOP: ELECTRONIC TROUBLESHOOTING MANUAL (ETM) SERVICE TIPS - In an effort to increase the amount of Service Information available to our Kia Service technicians, KGIS offers a section called "Service Tips" located in the Electronic Troubleshooting Manual (ETM). These Service Tips provide valuable Service Information for individual systems, circuit description and operation. Additionally, technicians can benefit from all the available Powertrain Control Module (PCM) information which includes detailed circuit description, condition, input and output signal type and level (range) and oscilloscope patterns (for good signal reference).
