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 B wire
and P wire ) and (between G wire
STVA resistance: Approx. 6.5 Ω
\ 09900-25008: Multi-circuit tester set
V Tester knob indication: Resistance (Ω)
Is the resistance OK?
• W/B, P/W, G and B/Lg wire open or shorted to
ground, or poor
• 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.
