Transaxle/Transmission Range Switch

Check for starter operation with ignition switch in START position and shift lever in "P" and "N" position only. Ensure back-up lights illuminate with ignition in "ON" position and selector lever in "R" position.
To test switch, disconnect Transaxle/Transmission Range (TR) switch harness connector. Check for continuity between specified terminals at TR switch. See Fig 1, Fig 2, Fig 3, Fig 4, Fig 5 or Fig 6 . If continuity is not as specified, replace TR switch. On Mazda6 2.3L only, if TR switch is okay, go to next step.
Recheck TR switch resistance. Measure resistance between TR switch terminals "B" and "C". See Fig 1. If resistance readings are not as specified, replace TR switch.
