If Tech 2 does not respond correctly, the current to pin 10 on the switch must be checked. Check the current on pin 4 of the switch unit and pin 42 on K42 when the soft top is opened. Check the current on pin 3 of the switch unit and pin 28 on K42 when the soft top is closed. Check the ground connection on pins 8 and 12 of the switch. Change the switch or repair the wiring harness if necessary.

Defective fuse? (If the TSAS system cannot be contacted with Tech 2, one of the fuses may be defective.)

Investigate the cause of the blown fuse (short to ground, etc.). Rectify the fault and then change the fuse.

Nothing will happen if SID has not been correctly programmed when an attempt is made to lower the soft top while the soft top storage is up and SID will not display any error messages.
