Staging switch mismatch.
ACCESS 3 height switch (HGTS1) input different than
ACCESS 1 height switch (HGTS1) input.
Step 1: Enter the Analyzer menu A2.1.4 then A2.3.4
and record the reading of each with key on, operator on
presence switch and mast below staging height.
• If: A2.3.4 reads “1” while A2.1.4 reads “0”.
– Then proceed to Step 2.
• If: A2.1.4 reads “1” while A2.3.4 reads “0”.
– Then proceed to Step 3.
Step 2: Check voltage between ACCESS 3 CA403-10
(+) and TP6 (-) on the distribution panel with key on,
operator on presence switch and mast below staging
height.
• If: Battery volts.
– Then replace ACCESS 3.
• If: Battery volts.
– Then check wiring and connections between
CA201-8 on distribution panel and CA408-10
on ACCESS 3. Repair/replace as needed. If
OK, proceed to Step 4.
Step 3: Check voltage between CA215-15 (+) on
ACCESS 1 and TP6 (-) on the distribution panel with
key on, operator on presence switch and mast below
staging height.
• If: Battery volts.
– Then replace ACCESS 1.
• If: Less than battery volts.
– Then check wiring and connections between
CA201-11 on the distribution panel and
CA215-15 on ACCESS 1. Repair/replace as
necessary. If OK, proceed to Step 4.
Step 4: Check voltage between CA201-8 and TP6 (-)
and between CA201-11 and TP6 (-) on the distribution
panel with key on, operator on presence switch and
mast below staging height.
• If: Both checks are battery volts.
– Then re-key and monitor truck.
• If: Either check is less than battery volts.
– Then replace distribution panel.
