Connect a scan tool to the vehicle, switch to live data and move the shift level through all positions. When the shift lever is in Park, the state should read P/N, Reverse should read R, Neutral should read P/N, Drive should read D. If so, that confirms there’s no open or short circuit between the PCM/TCM and range switch.

Next, adjust the transmission range selector with the shifter in the NEUTRAL position.

Insert a 5mm drill or M5 (5mm) bolt in the adjustment hole of the range switch. Check

into the adjustment holes.

If the drill or bolt fits, Inspect the connector to the range switch for a bent pin or pin not fully
inserted and related wiring for an open or short circuit. If OK, replace the transmission range selector switch.

If the drill or bolt doesn’t fit, adjust the transmission range selector switch.

Loosen the two 10 mm mounting bolts. Then disconnect the shift cable at the lever. Insert a 5mm drill or M5 (5mm) bolt in the adjustment hole of the range switch. Tighten the two 10 mm mounting bolts to specification. Torque Specification: 7-8 lb ft. (10-12 Nm, 100-120 kg.cm)

Drive the vehicle two key-on to key-off drive cycles, including shifting to gears D, 3,
2, L (if equipped) and R. If the trouble code does not reset, the repair is complete.

If the codes reset repair or replace the control harness. If they still reset after replacing the harness, replace the TCM.
