锟斤拷If 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. Also test each circuit for a short to ground.
锟斤拷If all circuits test normal, continue with testing.
锟斤拷If 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. 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.
锟斤拷If any of the circuits are not within the specified range, repair or replace the wiring harness.
锟斤拷If 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.
锟斤拷If 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
锟斤拷Repair, replace or clean the connector as appropriate.
4. Reconnect all connectors and test drive the vehicle.
锟斤拷If the DTC sets, replace the applicable drive motor generator and retest for DTCs. If the DTC sets, replace the PIM.
