Inspect wiring harness for broken wire or bad connections. (Repair/Replace as required).
Test supply ground circuit to GCU using a continuity OHM/tester. Refer to page 39.
Test 1: Identify wire ends in connector. Using a
digital multi-meter set to lowest scale (0-200 ohms)
place probes onto harness making sure of a good
connection. Resistance should be between 47.7 and
58.3 ohms. Refer to page 39.
If either test fails, DLA is no good and should be
replaced. If both tests are good, DLA is neither shorted
or open, and should be good. Another component,
connection, or input is most likely at fault.
Test 2: Identify wire ends in connector. Using a
digital multi-meter set to lowest scale (0-200 ohms)
place probes onto harness making sure of a good
connection. Resistance should be between 47.7 and
58.3 ohms. Refer to page 39.
Proceed to DLA
Circuit Test.
Test supply voltage to GCU using volt meter. Refer to page 39 (battery voltage +/- 1 volt) Note: Prevent
Damage to Connector. Do Not Use Oversized Probe Tips.
If a Stepper Motor Controller Tool is available (see Tools and Aids), DLA
function can be tested and confi rmed. Testing instructions are included
with tool. If tool is not available, proceed to DLA Circuit Test.
If test fails, DLA is no good and should
be replaced. If DLA test is good, another
component, connection, or input is most
likely at fault. Replace GCU and harness.
