ACCESS 2 Travel Alarm (ALM2) Reads Short
across Output (DC Hydraulic models).
Step 1: From ACCESS 1, Level 3, Analyzer menu
A4.2.1 and with DVOM across ALM2, test drive output
from ACCESS 2.
• If: 33-35 Vdc.
– Then output driver is ok, reset code and moni-
tor for reoccurrence.
• If: Less than 33-35 Vdc.
– Then output driver is not working or is sensing
a short circuit; proceed to Step 2.
Step 2: Check for short from negative wire of ALM2 to
+BV by checking voltage from BNEG to ALM2 positive
wire.
• If: 33-35 Vdc.
– Then negative wire is shorted to +BV, trace
wire to CA405-28 and repair wiring.
• If: Less than 5 Vdc.
– Then proceed to Step 3.
Step 3: Disconnect wires and check ALM2 for internal
short using ohmmeter, should read 35 to 45 ohm.
• If: Less than 35 ohm.
– Then replace ALM2.
• If: 35-45 ohm.
– Then replace ACCESS 2.
