Is there less than 3 ohms ?
YES - Go to step 9.
NO - Replace the A/T clutch pressure control solenoid valve A, then go to step 12.
9. Jump the SCS line with the HDS.
10. Disconnect PCM connector A (73P).
11. Check for continuity between PCM connector terminals A39 and body ground, between A40 and body ground, and between A73 and body ground.
Is there continuity ?
YES - Update the PCM if it does not have the latest software, or substitute a known-good PCM, then recheck. If the symptom/indication goes away with a known-good PCM, replace the original PCM. A
NO - Repair open in the wires between PCM connector terminals A39, A40, A73, and ground (G101, G102), or repair poor ground (G101, G102), then go to step 12.
