Diagnostic Mode

MODE 1
Diagnostic Mode 1 clears soft limits and sets memory selector switches (1 and 2) to predetermined values.

Activation
Press and hold the S and 1 buttons for 5 seconds to enter diagnostic mode 1. This mode is exited at the completion of the mode 1 tasks or upon grounding the DATA G87 circuit input to the MSMM.

Mode 1 will:
- Clear all soft limits to their default hard limit values
- Load memory 1 with default settings corresponding to horizontal rearward, front down, rear down, and recliner rearward positions
- Load memory 2 with default settings corresponding to horizontal forward, front up, rear up, and recliner forward positions

MODE 2
Diagnostic mode 2 provides a way to determine if the seat/mirror motors and position sensors are connected properly.

Activation
Press and hold the S and 2 buttons for 5 seconds to enter diagnostic mode 2. This mode is exited after 5 seconds of switch inactivity or upon grounding the DATA G87 circuit input by moving the transmission out of the PARK position.

Mode 2 will:
- Place the seat and mirror motors at their midpoint
- When a single axis of seat or mirror motion is requested by pressing a switch, the corresponding motor is energized. This tests switch input and motor output

- When the switch is released, the motor will automatically return to its original position. If the corresponding sensor is out of range, then the motor will not return to its original position. This tests the integrity of the sensors and motor outputs.
