We are using STM32L151VCT6A-ND IC in devices; where I observed that in some of the ICs pin PA13 (JTMS-SWDIO) is low and not able to detect the MCU. Could anyone please help me to solve this issue.

I was not able to connect to the ST-Link; 'No target connected' Error message is displaying.

Pin PA13 (JTMS-SWDIO) is low.  Is it possible to make it pull-high? 

Even I have tried making pin PA13 pull-up externally..

Have you tried to enter DFU - I mean embedded bootloader firmware where the SWD pin is enabled?
