SVA2A Solenoid Coil Circuit Open.
Event logged if an open circuit exists between SVA2A
and driver CA230-9.
Note:
Step 1: Drive SVA2A through Analyzer menu A4.4.9 in
display and measure voltage across SVA2A 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 SVA2A is open, replace SVA2A.
• If: 0 Vdc.
– Then a positive or negative is missing, proceed
to Step 2.
Step 2: Drive SVA2A through Analyzer menu A4.4.9 in
display and measure voltage from +BV to SVA2A 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 SVA2A through analyzer mode in display
and measure voltage between CA230-9 (-) and +BV
with wiring connected.
• If: +BV.
– Then wiring is open from CA230-9 to SVA2A
(-).
• If: 0 Vdc.
– Then open is internal, replace ACCESS 7.
Step 4: Drive SVA2A through analyzer mode in display.
Measure voltage between CA230-12 (+) and BNEG.
• If: 30 Vdc.
– Then wiring is open from CA230-12 and
SVA2A (+).
• If: 0 Vdc.
– Then open is internal, replace ACCESS 7.
