SVTE Solenoid Coil Open Circuit.
Event logged if an open circuit exists between SVTE
and driver CA230-3.
Step 1: Drive SVTE through analyzer mode in display
A4.4.3 and measure voltage across SVTE coil with wir-
ing connected. Normal A4 test output voltage at coil is
approximately 21 Vdc. Coil resistance is approximately
39 ohms.
• If: 21 Vdc.
– Then SVTE is open, replace SVTE.
• If: 0 Vdc.
– Then a positive or negative is missing, proceed
to Step 2.
Step 2: Drive SVTE through Analyzer menu A4.4.3 in
display and measure voltage from +BV to SVTE(-) 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 SVTE through Analyzer menu A4.4.3 in
display and measure voltage between CA230-3(-) and
+BV with wiring connected.
• If: +BV.
– Then wiring is open from CA230-3 to SVTE.
• If: 0 Vdc.
– Then open is internal, replace ACCESS 7.
Step 4: Drive SVTE through Analyzer menu A4.4.3 in
display. Measure voltage between CA230-12 (+) and
BNEG.
• If: 21 Vdc.
– Then wiring is open from CA230-12 and SVTE
(+).
• If: 0 Vdc.
– Then open is internal, replace ACCESS 7.
