Emergency switch
1. Check that S21 is not actuated.
2. If LeD 809 does not come there is a break in the circuit.
If Led 809 comes on the error code could be due to a loose
connector in the circuit. Check cable 22 by removing it from
terminal 809 and measure using an ohmmeter to terminal 2 on
S21. Also check the connector pins for play and oxidisation. If
the cable is intact, continue to measure with the ohmmeter
through S21 to terminal 1. If S21 is not depressed there should
be no breakage. If everything is OK, check that the connection
between S16 and S21 is intact.
3. If S21 and its cables are okay, replace the A5 card.
