CAUTION / NOTICE / HINT

NOTICE:
·

When using the GTS with the vehicle ignition switch off, connect the GTS to the DLC3 and turn a courtesy light switch on and off at intervals of 1.5 seconds or less until communication between the GTS and the vehicle begins.

·

Inspect the fuses for circuits related to this system before performing the following procedure.

·

The power door lock control system uses the CAN communication system. Inspect the communication function by following How to Proceed with Troubleshooting. Troubleshoot the power door lock control system after confirming that the communication systems are functioning properly.
