The present invention is an electronic control apparatus for control of an automatic transmission in a motor vehicle which controlling a motor to shift the transmission to said desired transmission state when the desired transmission state differs from the present transmission state signal. The electronic control apparatus detects and stores any faults in controlling the motor, and generates an output indicating any stored fault codes in response to a particular operator input. In the preferred embodiment the operator input is via plural push-buttons with corresponding lamps. In normal operation a single lamp is turned ON to indicate the present gear. Fault codes are indicated by turning ON the lamps in a code corresponding to the fault code. Detected faults include invalid transmission state signal, time out without completing the shift and over current in the motor. The preferred embodiment further includes an input/output port for receiving commands to read the stored fault codes, to read vehicle condition inputs to the electronic controller and to cause the electronic controller to control the motor to shift the transmission to a commanded state. |
