Circuit/System Verification

1. Clear the DTC information.

2. Turn the ignition OFF for 1 minute.

3. Turn the ignition ON.

4. Test for correct operation of the direction and range IMS switch circuits in every gear selection. Hold the selector in each gear position for at

least 2 seconds. Refer to Typical Scan Tool Data.

瀚慖f the Direction IMS operation does not match the logic table proceed with Circuit/System Testing.

瀚慖f the IMS A/B/C/P operation does not match the logic table proceed to DTC P1824, P182A-P182F, P1838, or P1839 ( See: P Code

Charts/P1824).

5. Retest for DTC P183F

瀚慖f the DTC resets, program the PIM with the latest software version and recheck for DTCs. If the DTC resets after programming or if the

PIM already contains the latest software version, replace the PIM.
