Test Tb: Step 5

5) Check Output Driver Signal  Turn key off. Install breakout box, leaving ECA connected. Disconnect A4LD transmission bulkhead connector. Connect a test light between test pin No. 37 or 57 and appropriate signal output pin at the breakout box. Enter KOEO Self-Test. If test light flashes momentarily and then stays off, fault is internal in transmission. Repair internal electrical fault as necessary. If light does not flash momentarily and then stay off, replace ECA. Remove breakout box and reconnect all components. Repeat QUICK TEST.
