FI SYSTEM DIAGNOSIS 5-59
Step 2
1) Turn the ignition switch OFF.
2) Disconnect the STVA lead wire coupler.
3) Check the continuity between each terminal and ground.

(Infinity)
(Terminal – Ground)
4) If OK, then measure the STVA resistance (between Black
wire
A
and Pink wire
B
) and (between Green wire
C
and
W/BI wire
D
).

• Recheck each terminal and wire harness for
open circuit and poor connection.
• Replace the ECM with a known good one, and
inspect it again.
NO
• Loose or poor contacts on the ECM coupler.
• Replace the STVA with a new one.
