Monitor description: Notes
WARNING: This page is about a different variant/trim than selected.
These diagnostic codes indicate problems of the wiring harness in the neutral start switch ASSY and neutral start switch ASSY circuit.
The neutral start switch ASSY detects the select lever position and sends signals to TCM.
For safety, the neutral start switch ASSY detects the select lever position. It is to allow the engine to start only when the select lever is in P or N position.
The neutral start switch ASSY sends signals corresponding to shift positions (P, R, N, D, or M) to TCM. When receiving 2 or more position signals at one time, TCM determines that the switch or related parts have a problem. TCM turns on MIL and records the diagnostic codes.
If open or short circuit is detected, all contacts of shift positions are turned to OFF.
