Automatic Transmission:
Circuit/System Verification
1. Ignition ON, observe the DTC information with a
scan tool.
2. Record Freeze Frame and Failure Records.
3. Clear DTC's.
4. Engine running, using PC Solenoid Output Controls,
observe the PC Sol. Actual Current and PC Sol. Ref.
Current while varying the current. The actual and
commanded values should be within 0.05 amps.
5. Operate the vehicle under the conditions observed in
the Failure Records.
6. Observe the DTC information with the scan tool.
Verify that the DTC does not set.
Circuit/System Testing
1. Ignition OFF, disconnect the 22-way automatic
transmission (AT) wiring harness connector (C2) at
the TCM.
2. Test for 5-8 ohms of resistance between the PC
solenoid high control circuit terminal and low control
circuit terminal.
➢ If not within the specified range
– Remove the appropriate solenoid and test for 4-8
Ω of resistance.
➢ If not within the specified range, replace the valve
body assembly.
– Replace the AT wiring harness, refer to "Wiring
Harness Removal" procedure and "Wiring
Harness Installation" procedure.
3. Replace the TCM, refer to "Transmission Control
Module Removal" and "Transmission Control Module
Installation" procedure.
Component Testing
Test the PC solenoid for 5.0-5.6 Ω of resistance, at 20°C,
between the control circuit terminal and the ground
circuit terminal.
➢ If not within the specified range, perform the
"Control Valve Body Replacement" procedure.
Repair Instructions
Perform the "Diagnostic Repair Verification - Vehicle
Diagnostic Information: " after completing the diagnostic
procedure.
