The Powertrain Control/Emissions Diagnosis \(PC/ED\) manual has been revised for diagnosing electronic throttle bodies \(ETBs\). The ETC\_ACT and ETC\_DSD PIDs should not used to diagnose possible ETB concerns. The IDS has a limited refresh rate when reading these PIDs and cannot display quickly enough to validate a concern. The PCM automatically monitors these inputs more accurately and will set diagnostic trouble codes \(DTCs\) when appropriate. Using these PIDs for diagnostics will lead to inaccurate results and improper ETB replacements. If a concern is intermittent and no DTCs are present, refer to historical DTCs and the PC/ED, Section 3 No DTCs Present Index chart for further information. - [ASI\-45201](/bulletins/10058596.md), 2015-10-20, Service bulletin: ENGINE AND ENGINE COOLING:COOLING SYSTEM:FAN.
