The fault indicators on the remote annunciator or the fault indicators on the alarm module are flashing at a rate of 0.5 Hz (every two seconds).
Test Step 1. Inspect Electrical Connectors and Wiring
- Turn the main disconnect switch to the OFF position.
- Thoroughly inspect all of the connectors that are associated with the circuit.
Expected Result:
All connectors, pins and sockets are completely coupled and/or inserted and the harness and wiring are free of corrosion, of abrasion and of pinch points.
Results:
- OK - The harness and connectors appear to be OK. Proceed to Test Step 2.
- Not OK - There is a problem with the connectors and/or wiring.
Repair: Repair the connectors or wiring and/or replace the connectors or wiring. Ensure that all of the seals are properly in place and ensure that the connectors are completely coupled.Verify that the repair eliminates the problem.
STOP
Test Step 2. Check the Status Control Module (SCM)
Turn the main disconnect switch to the ON position.
Expected Result:
After reconnecting the +Battery to the SCM, the fault indicators are no longer flashing.
Results:
- OK - The fault indicators are no longer flashing.
Repair: There may be an intermittent problem.Inspect the electrical connectors and wiring.If necessary, repair the connectors or wiring and/or replace the connectors or wiring.Verify that the repair eliminates the problem.
STOP
- Not OK - The fault indicators continue to flash. There may be a problem with the data link. Proceed to Test Step 3.
Test Step 3. Check the Data Link
- Turn the main disconnect switch to the OFF position.
- Disconnect the data link from terminal 6 on the SCM and from terminal 2 on the Alarm Module (ALM).
- Check the continuity of the data link.
Expected Result:
The data link does not have continuity.
Results:
- OK - The data link does not have continuity.
Repair: Repair the connectors or wiring and/or replace the connectors or wiring. Verify that the repair eliminates the problem.
STOP
- Not OK - The data link has continuity.
Repair: Troubleshoot the SCM.If necessary, repair the SCM or replace the SCM.If the SCM is OK, troubleshoot the ALM and/or the remote annunciator.If necessary, replace the ALM and/or replace the remote annunciator.Verify that the repair eliminates the problem.
