| TEST PROCEDURE | RESULT | CORRECTIVE ACTION | |
|---|---|---|---|
| A1 | CHECK TRANSMITTER | OK NOT OK | Carry out step A2 Replace the battery of the transmitter. If the signal is not getting through check and if necessary replace the transmitter. N.B.: in this case it will be necessary to memorize a new code on receiver N67 (see "Memorizing of the secret code"). |
| - Check that the batteries of the transmitter are not flat (the correct emission of the infrared rays is signalled by the illumination of the led on the transmitter itself) | |||
| A2 | CHECK RECEIVER | OK NOT OK | Carry out step A3 Carefully clean the surface of the half-sphere. Check and if necessary replace the receiver N67. N.B.: in this case it will be necessary to follow the code memorization procedure on the new receiver N67 to store the previous code or the code of a new transmitter (see "Memorization of the secret code") |
| - Check that the infrared signal is being picked up by the receiver N67 (the correct reception of a signal is indicated by the illumination of the led located on the receiver itself) | |||
| A3 | CHECK FUSE | OK NOT OK | Carry out step A4 Replace the fuse (7.5A) |
| - Check fuse F16 in fusebox G1 for damage | |||
| A4 | CHECK GROUND | OK NOT OK | Carry out step A5 Restore wiring between pin (-) of N67 and ground G148b, across pin D4 of connector G73 and pin 3 of rheostat B16 (BLK) |
| - Check for 0V at pin (-) of the receiver device N67 | |||
| A5 | CHECK VOLTAGE | OK NOT OK | Replace the receiver N67. N.B.: in this case it will be necessary to follow the code memorization procedure on the new receiver N67 to store the previous code or the code of a new transmitter (see "Memorization of the secret code") Restore wiring between pin (+) of N67 and pin D7 of fusebox G1, across pin D1 of connector G73 and the solder (RED) |
| - Check for 12 V at pin (+) of receiver device N67 | |||
