Mode 2
Diagnostic mode 2 shows if seat/mirror motors and position sensors are connected properly. To activate, press and hold "S" and "2" buttons for 5 seconds. Mode 2 is exited after 5 seconds of switch inactivity or when RKE input to MSM module is grounded. The RKE input is grounded by shifting transmission out of Park. Mode 2 will:
- Adjust seat and mirror motors to midpoint.
- To test switch input and motor output, seat or mirror motors will respond to single axis switch requests.
- When switch is released, motors will automatically return to original position. If sensor for motor is out of range the motor will not return to original position. This test checks integrity of sensor and motor outputs. For circuit descriptions see appropriate CONNECTOR TERMINAL IDENTIFICATION table. See Fig 1 -Fig 3 .
