SVA1B Solenoid Coil Open.
Step 1: Drive SVA1B through analyzer menu A4.4.8
and measure voltage across SVA1B with wiring con-
nected. Normal A4 test output voltage at coil is approx-
imately 30 Vdc. Coil resistance is approximately 39
ohms.
• If: 30 Vdc.
– Then SVA1B is open, replace SVA1B.
• If: 0 Vdc.
– Then a positive or negative is missing, proceed
to Step 2.
Step 2: Drive SVA1B through analyzer menu in display
and measure voltage from +BV to SVA1B negative with
wiring in tact.
• If: 0 Vdc.
– Then negative is missing; proceed to Step 3.
• If: +BV.
– Then positive is missing; proceed to Step 4.
Step 3: Drive SVA1B through analyzer menu in display
and measure voltage between CA230-7 (-) and +BV
with wiring connected.
• If: +BV.
– Then wiring is open from CA230-7 to SVA1B
(-).
• If: 0 Vdc.
– Then open is internal, replace ACCESS 7.
Step 4: Drive SVA1B through analyzer menu in display.
Measure voltage between CA230-12 (+) and BNEG.
• If: 30 Vdc.
– Then wiring is open from CA230-12 and
SVA1B (+).
• If: 0 Vdc.
– Then open is internal, replace ACCESS 7.
