Pinpoint Test Ac : DTC P163E, P163F

WARNING: This page is about a different variant/trim than selected.

Normal Operation and Fault Conditions

All CIDAS shift solenoids are calibrated from the factory, but not all solenoids are the same. Each solenoid is labelled with a band number, and each main control valve body has a 13-digit solenoid body strategy and a 12-digit solenoid body identification. This information must be downloaded into the PCM, or harsh shifts may occur.
