In most circumstances, the PCM sets DTCs to help guide with diagnostics. Refer to the DTC Chart before using the symptom chart. The Condition column lists the vehicle condition. The Source column lists a detailed vehicle condition. The Action column lists the action to be performed to determine the cause of the condition. Each action lists the components that can caused the system and the individual components in that system. The components are listed in order of disassembly. Use the list of components and the required action to focus on disassembly inspections for the root cause of the concern.

Normal Operation and Fault Conditions

The low gear select switch is a momentary contact switch located on the end of the selector lever. Pressing the low gear select switch will allow for low (1st gear) operation or cancel low gear operation. There are no continuous DTCs for the low gear select switch but if the switch fails while the vehicle is being driven, the symptoms is, transmission shifts to low when not selected or transmission will not go into low when selected. This will depend on how and when the switch fails.
