SVA1A Solenoid Coil Circuit Open.
Event logged if an open circuit exists between SVA1A
and driver CA230-8.
Step 1: Drive SVA1A through Analyzer menu A4.4.7 in
display and measure voltage across SVA1A with wiring
connected. Normal A4 test output voltage at coil is ap-
proximately 30 Vdc. Coil resistance is approximately
39 ohms.
• If: 30 Vdc.
– Then SVA1A is open, replace SVA1A.
• If: 0 Vdc.
– Then a positive or negative is missing; proceed
to Step 2.
Step 2: Drive SVA1A through Analyzer menu A4.4.7 in
display and measure voltage from +BV to SVA1A neg-
ative 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 SVA1A through Analyzer menu A4.4.7 in
display and measure voltage between CA230-8 (-) and
+BV with wiring connected.
• If: +BV.
– Then wiring is open from CA230-7 to SVA1A
(-).
• If: 0 Vdc.
– Then open is internal, replace ACCESS 7.
Step 4: Drive SVA1A through Analyzer menu A4.4.7 in
display. Measure voltage between CA230-12 (+) and
BNEG.
• If: 30 Vdc.
– Then wiring is open from CA230-12 and
SVA1A (+).
• If: 0 Vdc.
– Then open is internal, replace ACCESS 7.
