EBL Status Indicator Flashing
EBL STATUS INDICATOR FLASHING
Theory of Operation
Running the HVAC Door Recalibration will cause the EBL status indicator to flash. If recalibration fails, the status indicator will continue to flash
until either the system passes recalibration or the ignition key is cycled. When the EBL status indicator is flashing, it will not indicate EBL operating
status. However, the EBL mode switch will continue to function normally. When the EBL status indicator is flashing, the A/C status indicator will not
function. However, the A/C mode switch will continue to function normally.
POSSIBLE CAUSES
-
HVAC door recalibration failed
1. PERFORM THE HVAC DOOR RECALIBRATION
Turn the ignition on.
With the DRBIII(R) in HVAC, select System Tests and then select HVAC Door Recalibration.
Allow the test to run to completion before proceeding.
Q: Does the DRBIII(R) display: Recalibration Test Passed?
YES: Test Complete. Perform BODY VERIFICATION TEST - VER 1. See: Powertrain Management/Computers and Control Systems/Testing
and Inspection/Diagnostic Trouble Code Tests and Associated Procedures/Verification Tests/Body Verification Test
NO: Diagnose and repair the fault(s).
