Step 2
1) Turn the ignition switch OFF.
2) Disconnect the STVA lead wire coupler.
3) Check the continuity between each terminal and ground.
" STVA continuity: ∞ Ω (Infinity)
4) If OK, then measure the STVA resistance (between Black
wire A and Pink wire B) and (between Green wire C and W/
B wire D).
" STVA resistance: Approx. 6.5 Ω
# 09900-25008: Multi-circuit tester set
) Tester knob indication: Resistance (Ω)
Is the resistance OK?
• B/Lg, P/W, Green and W/B wire open or shorted
to ground, or poor Y, [, d and f connection.
• If wire and connection are OK, intermittent trou-
ble or faulty ECM.
YES
• Recheck each terminal and wire harness for
open circuit and poor connection.
• Replace the ECM with a known good one, and
inspect it again.
• Loose or poor contacts on the ECM coupler.
NO
• Replace the STVA with a new one.
5) After repairing the trouble, clear the DTC using SDS tool.
