1. Remove the center console.
2. Disconnect the switch assembly connector (6P).
3. Check for continuity between the No. 3 and No. 1 terminals of the switch assembly connector (6P) when the shift lever is in the [1] position, and then in all positions other than [1].
Is there continuity when the shift lever is in [1] position, and no continuity when the shift lever is in all positions other than [1]?

NO - Go to step 7.
7. Turn the ignition switch off.
8. Disconnect PCM connector E (20P).
9. Check for continuity between PCM connector E terminal No. 14 and body ground.
