transmission bulkhead connector.

(2) Connect breakout harness

connector to transmission bulkhead

connector.

(3) Is there continuity between

terminal E and any other wire on

breakout harness connector?

(a) If there is continuity, replace

solenoid wiring harness

assembly (Para 7-2).

(b) If there is no continuity, go to

Step (4) below.

(4) Is there continuity between

terminal H and any other wire on

breakout harness connector?

solenoid wiring harness

assembly (Para 7-2).

(b) If there is continuity, go to

Step (7) below.

(7) Is there continuity between

terminal H on the breakout harness

connector and a known good

ground?

(a) If there is continuity, replace

solenoid wiring harness

assembly (Para 7-2).

(b) If there is no continuity, replace

ATEC ECU

(TM 9-2320-364-20).
