- Disconnect the X3 harness connector at the power steering module assembly.
- Connect the EL-47564 test harness Power Steering Control Module (PSCM) Test Harness.
- Ignition OFF, test for less than 2 Ω between the low reference circuit terminal E and ground.
- If greater than the specified range, replace the power steering control module.
- Ignition ON, test for 4.8-5.2 V between the 5 V reference circuit terminal B and ground.
- If less than the specified range, replace the power steering control module.
- Install a 3A fused jumper wire between the signal circuit terminal F and the 5V reference circuit terminal B. Verify the scan tool Torque Sensor Signal 1 is greater than 4.8V.
- If less than the specified value, replace the power steering control module.
- Install a 3A fused jumper wire between the signal circuit terminal C and the 5V reference circuit terminal B. Verify the scan tool Torque Sensor Signal 2 is greater than 4.8V.
- If less than the specified value, replace the power steering control module.
- If all circuits test normal, test or replace the steering column.
