TEST ACTION APPLICABILITY
3 NOTE: Inspect all air intake and turbocharger related tubes for damage,
restriction or poor connection.Any of these conditions can cause a this DTC
to set.
Turn the ignition off.
Inspect all air intake and turbocharger related tubes and connections.
Were any problems found?
All
Yes → Repair or replace as necessary.
Perform ROAD TEST VERIFICATION - VER-2.
No → Go To 4
4 With the DRBIIIt, read the active and stored DTCs for the Transmission Control
Module.
NOTE: Due to capabilities of certain controllers that use the CAN Bus, not
all modules report CAN Bus DTCs.
Is the TCM reporting active or stored CAN Bus communication DTCs related to the
Shifter Module?
All
Yes → Refer to symptom list to diagnose CAN Bus DTC in the TCM.
Perform ROAD TEST VERIFICATION - VER-2.
No → Go To 5
5 Turn the ignition off to the lock position.
Disconnect the Shifter Module harness connector.
Disconnect the ECM harness connector.
NOTE: Check connectors - Clean/repair as necessary.
Measure the resistance of both the CAN C Bus (+) circuit and the CAN C Bus (-)
circuit between the Shifter Module harness connector and ECM harness connector.
Is the resistance below 10.0 ohms for each measurement?
All
Yes → Go To 6
No → Repair the CAN C Bus (+) and/or CAN C Bus (-) circuit for an
open.
Perform ROAD TEST VERIFICATION - VER-2.
6 Turn the ignition off.
Disconnect the Intake Pressure Sensor harness connector.
Disconnect the ECM harness connectors.
Measure the resistance of the Intake Pressure Sensor Signal circuit.
Is the resistance below 10.0 ohms?
All
Yes → Go To 7
No → Repair the Intake Pressure Sensor Signal circuit for high resis-
tance.
Perform ROAD TEST VERIFICATION - VER-2.
7 Turn the ignition off.
Disconnect the Intake Pressure Sensor harness connector.
Disconnect the ECM harness connectors.
Measure the resistance of the Sensor Ground circuit.
Is the resistance below 10.0 ohms?
All
Yes → Go To 8
No → Repair the Intake Pressure Sensor Ground circuit for high resis-
tance.
Perform ROAD TEST VERIFICATION - VER-2.
