20. Jump the SCS line with the HDS.
21. Disconnect PCM connector A (44P).
22. Connect PSP switch 2P connector terminal No.1 to body ground with a jumper wire.
23. Check for continuity between body ground and PCM connector terminal A22.
Is there continuity? YES-Go to step 24.
NO-Repair open in the wire between the PSP switch and the PCM (A22).
24. Check for continuity between PSP switch 2P connector terminal No.2 and body ground.
