Output Testing

1. Make sure the BCM is in self-test and you have retrieved DTCs.
2. Turn the IP dimmer switch to the DOME position to begin the first output test.
3. Turn the IP dimmer switch from DOME to OFF and back to DOME to step through the 7 tests listed:
^ Test 1 - turns OFF all interior lamps
^ Test 2 - turns ON the interior lamps
^ Test 3 - turns ON all courtesy lamps
^ Test 4 - energizes the theft deterrent relay for 1 second and turns ON the headlamps, for BCM Type 4 only
^ Test 5 - energizes the horn relay for 25 ms and turns ON the horn, for BCM Type 4 only
^ Test 6 - turns ON the theft deterrent indicator lamp, for BCM Type 4 only
^ Test 7 - turns OFF the theft deterrent indicator lamp, for BCM Type 4 only
4. The BCM sounds the chime to indicate the output test number.
5. Once all tests are completed, the cycle will repeat with each DOME-OFF-DOME cycle of the IP dimmer switch.
Remember that the maximum number of output tests for Type 2 and Type 3 BCMs is 3.
