2. Connect jumper pin 2 of the automatic transmission control relay to the negative (-) battery terminal and contact 4 of the control relay with positive (+) battery terminal (pic. 13.23).
Pic. 13.23. Checking the automatic transmission control relay
3. Check continuity between tracks 1 and 3 of the automatic transmission control relay when the jumpers are connected and disconnected from the battery.
When connecting jumpers between the relay terminals, there must be conductivity.
When disconnecting the jumpers between the relay terminals, there should be no conduction.
4. If test results are negative, replace the relay.
