DTC P176C-07: Transmission Range Selector Lock Control Error - Mechanical Failures: Action

Check for normal shift interlock lock/unlock operation, and check for short circuit diagnostic trouble codes. If the transmission shift module locks and unlocks normally then no further action is required. If the transmission shift module fails to lock normally when fully in the P position it may be due to an internal fault. Check and install new transmission shift module as required. Refer to the warranty policy and procedures manual, or determine if any prior approval program is in operation, prior to the installation of a new module/component
