Sensor Tests

CAUTION: Be sure that the DIGITAL 12 pin sensor cable connector (black) is used. If the wrong connection is made or the slide switch is in the wrong position, the LEDs on the TR cable will give false or no response during testing. This will cause the replacement of good parts.

1. Place transmission range selector lever into PARK.
2. Ensure that the "E" cable ANALOG/DIGITAL switch is set to DIGITAL.
3. Move the transmission range selector lever through all ranges.
4. Monitor the LEDs, located on the "E" cable, in each gear position. The LED should illuminate RED for the appropriate range selected.
5. If the LED for the applicable gear range position fails to illuminate RED or if it lights for a position other than the gear selected:
- Verify test cable connections at sensor and tester.
- Verify transmission shift linkage for proper adjustment.
- Verify DTR sensor for proper adjustment.
- Retest.

6. If the sensor still fails to illuminate the LED RED for the selected gear range or indicates incorrect gear position, replace it.
