SVTR Solenoid Coil Open Circuit.
Event logged if an open circuit exists between SVTR
and driver CA230-4.
Step 1: Drive SVTR through Analyzer menu A4.4.4 in
display and measure voltage across SVTR coil with
wiring connected. Normal A4 test output voltage at coil
is approximately 21 Vdc. Coil resistance is approxi-
mately 39 ohms.
• If: 21 Vdc
– Then SVTR is open, replace SVTR.
• If: 0 Vdc.
– Then a positive or negative is missing, proceed
to Step 2.
Step 2: Drive SVTR through Analyzer menu A4.4.4 in
display and measure voltage from +BV to SVTR (-) 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 SVTR through Analyzer menu A4.4.4 in
display and measure voltage between CA230-4(-) and
+BV with wiring connected.
• If: +BV.
– Then wiring is open from CA230-4 to SVTR.
• If: 0 Vdc.
– Then open is internal, replace ACCESS 7.
Step 4: Drive SVTR through Analyzer menu A4.4.4 in
display. Measure voltage between CA230-12 (+) and
BNEG.
• If: 21 Vdc.
– Then wiring is open from CA230-12 and SPA
(+).
• If: 0 Vdc.
– Then open is internal, replace ACCESS 7.
