PRVA Solenoid Coil Circuit Open.
Event logged if an open circuit exists between PRVA
and driver CA230-6.
Step 1: Drive PRVA through Analyzer menu A4.4.6 in
display and measure voltage across PRVA with wiring
connected.
• If: 33-35 Vdc
– Then PRVA is open, replace PRVA.
• If: 0 Vdc.
– Then a positive or negative is missing, proceed
to Step 2.
Step 2: Drive PRVA through Analyzer menu A4.4.6 in
display and measure voltage from BNEG to PRVA neg-
ative with wiring connected.
• If: 0 Vdc.
– Then negative is missing, proceed to Step 3.
• If: 33-35 Vdc.
– Then positive is missing, proceed to Step 4.
Step 3: Drive PRVA through Analyzer menu A4.4.6 in
display and measure voltage between CA230-6 (-) and
+BV with wiring connected.
• If: 33-35 Vdc.
– Then wiring is open from CA230-6 to PRVA (-).
• If: 0 Vdc.
– Then open is internal to Access, replace
ACCESS 7.
Step 4: Drive PRVA through Analyzer menu A4.4.6 in
display. Measure voltage between CA231-10 (+) and
BNEG.
• If: 33-35 Vdc.
– Then wiring is open from CA231-10 and PRVA
(+).
• If: 0 Vdc.
– Then open is internal, replace ACCESS 7.
