At the harness side, connect PSP switch 2P connector terminals No. 1 and No. 2 with a jumper 10. Measure voltage between PCM connector terminals A26 and E20. Replace the PSP switch. Go to step 11. 11. Turn the ignition switch OFF. 12. Check for continuity between PSP switch 2P connector No. 2 terminal and body ground. Repair open in the wire between the PSP switch and PCM (E20). Repair open in the wire between the PSP switch and G201. 13. Turn the ignition switch OFF. 14. Disconnect the PSP switch 2P connector. 15. Turn the ignition switch ON (II). 16. Measure voltage between PCM connector terminals A26 and E20. Replace the PSP switch. Go to step 17. 17. Turn the ignition switch OFF. 18. Disconnect PCM connector E (31P). 19. Check for continuity between body ground and PCM connector terminal E20. Repair short in the wire between the PCM (E20) and the PSP switch. Substitute a known-good PCM and recheck (see page 11-5). If voltage is normal, replace the Wire side of female terminals Wire side of female terminals Wire side of female terminals Wire side of female terminals Is ther e less than 1.0 V ? Is ther e continuity? Is ther e batter y voltage? Is ther e continuity? 03/07/29 09:23:14 61S0X050_110_0198 |
