Circuit/System Verification
1. Perform the Range Selector Lever Cable Adjustment (See: Transmission and Drivetrain/Automatic Transmission/Transaxle/Shift
Linkage/Shift Cable/Adjustments) procedure to verify proper adjustment.
2. Ignition ON, observe the scan tool IMS parameter while moving the gear shift lever from Park, through all gear selector positions, and back
to Park. The parameter should match each gear range that is selected. Refer to Transmission Internal Mode Switch Logic (See:
Specifications/Mechanical Specifications/Automatic Transmission/Transaxle/System Specifications/6L45/6L50/6L80/6L90 - Automatic
Transmission/Transmission Internal Mode Switch Logic).
3. Observe the scan tool Engine Control Module P/N switch parameter with the gear selector in Park and Neutral position. The parameter
should display Park in park position and Neutral in neutral position.
4. Operate the vehicle within the Conditions for Running the DTC to verify the DTC does not reset. You may also operate the vehicle within the
conditions that you observed from the Freeze Frame/Failure Records data.
Circuit/System Testing
Note: You must perform Circuit/System Verification first.
1. Ignition OFF, remove the automatic transmission fluid pan. Refer to Automatic Transmission Fluid, Fluid Pan and/or Filter Replacement ().
2. Disconnect the IMS connector at the Q8 control solenoid valve assembly.
Note: Under certain driving conditions, DTC P182E could set due to an intermittent low voltage fault on the P/N signal circuit, before
conditions for setting DTC P0851 are met.
3. Ignition ON, verify the scan tool engine control module (ECM) P/N switch displays In Gear.
瀚慖f not the specified value, test the P/N signal circuit for a short to ground. If the circuit tests normal, replace the engine control module.
4. Verify the scan tool IMS A/B/C/P parameter displays HI for all four signal circuits.
瀚慖f not the specified value, replace the Q8 control solenoid valve assembly.
5. Connect a 3A fused jumper wire between each transmission range signal circuit terminals listed below and the IMS ground circuit. The
appropriate scan tool IMS A/B/C/P parameter should display LOW when the terminal is connected to the IMS ground circuit.
* Switch Signal A: terminal E to terminal A
* Switch Signal B: terminal D to terminal A
* Switch Signal C: terminal C to terminal A
* Switch Signal P: terminal P to terminal A
瀚慖f not the specified value, replace the Q8 control solenoid valve assembly.

DT-48493 Jumper Harness
Circuit/System Testing
Note: The drive motor generator position sensor circuits require proper circuit integrity for correct system operation. Just a few ohms of
additional circuit resistance may cause position sensor signal degradation.
* Always inspect position sensor signal connectors for proper terminal contact.
* All diagnostic connections must be made with the approved test probes to prevent the creation of poor terminal contact.
* Connectors that contain position sensor signal circuits must always be clean and dry prior to mating. Foreign material or moisture within
the connector may cause sensor signal degradation.
1. Ignition OFF, disconnect PIM X1 connector.
2. Using the Position Sensor Specification table specifications listed below, test the position sensor resistance at the PIM X1 circuits as
indicated. Use the specifications for the drive motor generator that set the DTC. Also test each circuit for a short to ground.
瀚慖f any of the circuits are not within specification, continue with testing.
瀚慖f all circuits test normal, inspect for proper terminal contact at PIM X1 connector. If PIM X1 terminal contact tests OK, perform the
Intermittent Condition Testing below.
3. Disconnect the transmission X176 24-way connector.
4. Connect the DT-48493 to the X176 24-way connector at the transmission.
5. Using the Position Sensor Specification table specifications listed below, test the position sensor resistance at the transmission X176 circuits
as indicated. Use the specifications for the drive motor generator that set the DTC. Also test each circuit for a short to ground.
瀚慖f all circuits test normal, continue with testing.
瀚慖f any of the circuits are not within specification, test the internal transmission harness for the condition. If the internal transmission
harness tests OK, replace the applicable drive motor generator.
6. Disconnect DT-48493 from the transmission X176 24-way connector.
7. Connect DT-48493 to the transmission X176 24-way connector at the vehicle harness.
8. Disconnect PIM connector X1.
9. Using the PIM to Transmission Terminal Reference table listed below, test the vehicle harness continuity between PIM X1 and transmission
X176. Use the specifications for the drive motor generator that set the DTC. Also test these circuits for short to ground and to the shield
circuit if the shield circuit is not presently grounded to the PIM assembly.
瀚慖f any of the circuits are not within the specified range, repair or replace the wiring harness.
瀚慖f all circuits test normal, inspect transmission connector X176 for proper terminal contact. If transmission connector X176 tests OK,
inspect the harness for an intermittent concern.
Intermittent Condition Testing
1. If possible, determine which of the position sensor circuits have the intermittent condition by reviewing the Diagnostic Fault Information
table. For example, DTCs P0C57 and P0C52 only set for a short to ground condition on either the S1 or S3 circuit.
2. Using the Position Sensor Specification table listed below, monitor the position sensor circuits at PIM X1 connector while manipulating the
applicable harness and connectors.
瀚慖f any of the circuits are not within specification, repair the harness or terminal as required. If a harness repair is indicated and external
harness damage is not evident, the most likely location for internal wire damage is near the harness clamping locations.
3. Disconnect transmission X176 connector and inspect for the following:
* Proper terminal contact
* Proper terminal retention in the connector
* Foreign material or moisture
