SVH Solenoid Coil Open Circuit.
Event logged if an open circuit exists between SVH and
driver CA230-5.
Note:
Step 1: Drive SVH through Analyzer menu A4.4.5 in
display and measure voltage across SVH with wiring
connected. Normal A4 test output voltage at coil is ap-
proximately 7.5 Vdc. Coil resistance is approximately
29 ohms.
• If: 7.5 Vdc.
– Then SVH is open, replace SVH.
• If: 0 Vdc.
– Then a positive or negative is missing, proceed
to Step 2.
Step 2: Drive SVH through Analyzer menu A4.4.5 in
display and measure voltage from +BV to SVH nega-
tive with wiring connected.
• If: 0 Vdc.
– Then negative is missing, proceed to Step 3.
• If: +BV.
– Then positive is missing; proceed to step 4.
Step 3: Drive SVH through Analyzer menu A4.4.5 in
display and measure voltage between CA230-5 (-) and
+BV with wiring connected.
• If: +BV.
– Then wiring is open from CA230-5 to SVH (-).
• If: 0 Vdc.
– Then open is internal, replace ACCESS 7.
Step 4: Drive SVH through Analyzer menu A4.4.5 in
display. Measure voltage between CA230-12 (+) and
BNEG.
• If: 7.5 Vdc.
– Then wiring is open from CA230-12 and SVH
(+).
• If: 0 Vdc.
– Then open is internal to Access, replace
ACCESS 7.
