Diagnostic Test
WARNING: This page is about a different variant/trim than selected.
- CHECK FOR AN ACTIVE DTC
- Turn the ignition on.
- With the scan tool, read DTCs and record on the repair order.
Is the DTC active or pending?
Yes
- Go To 2
No
- Perform the INTERMITTENT CONDITION diagnostic procedure. Refer to INTERMITTENT CONDITION .
- CHECK FOR OTHER DTCS
- CHECK THE (F343) FUSED ASD RELAY OUTPUT CIRCUIT FOR AN OPEN/HIGH RESISTANCE
- Turn the ignition off.
- Disconnect the Wastegate Solenoid 1 harness connector.
- Turn the ignition on.
- Measure the voltage on the (F343) Fused ASD Relay Output circuit at the Wastegate Solenoid 1 harness connector.
Is the voltage equal to Battery voltage?
Yes
- Go To 4
No
- Repair the (F343) Fused ASD Relay Output circuit for an open or high resistance.
- Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
- CHECK THE (K137) WASTEGATE SOLENOID 1 CIRCUIT FOR AN OPEN/HIGH RESISTANCE
- Turn the ignition off.
- Disconnect the PCM-1 C2 harness connector.
- Measure the resistance of the (K137) Wastegate Solenoid 1 Control circuit between the Wastegate Solenoid 1 harness connector and the PCM-1 C2 harness connector.
Is the resistance below 3.0 Ohms?
Yes
- Go To 5
No
- Repair the (K137) Wastegate Solenoid 1 Control circuit for an open or high resistance.
- Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
- CHECK THE WASTEGATE SOLENOID 1 FOR PROPER OPERATION
- Connect the PCM-1 C2 harness connector.
- Turn the ignition on.
- With the scan tool, actuate the Wastegate Solenoid 1 to 100%.
- Measure the voltage between the (K137) Wastegate Solenoid 1 Control circuit and the (F343) Fused ASD Relay Output circuit at the Wastegate Solenoid 1 harness connector.NOTE:
Be certain the actuation is active when checking the circuit. The voltage should be approximately Battery voltage.
- With the scan tool, actuate the Wastegate Solenoid 1 to 0%.
- Measure the voltage between the (K137) Wastegate Solenoid 1 Control circuit and the (F343) Fused ASD Relay Output circuit at the Wastegate Solenoid 1 harness connector.NOTE:
The voltage should drop to 0.0 volts.
Is there Battery voltage with the actuation at 100% and 0.0 volts with the actuation at 0%?
Yes
- Replace the Wastegate Solenoid 1 in accordance with the Service Information.
- Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
No
- Go To 6
- CHECK RELATED HARNESS CONNECTIONS
- Perform any Service Bulletins that apply.
- Disconnect all PCM-1 harness connectors.
- Disconnect all related in-line harness connections (if equipped).
- Disconnect the related component harness connectors.
- Inspect harness connectors, component connectors, and all male and female terminals for the following conditions:
- Proper connector installation.
- Damaged connector locks.
- Corrosion.
- Other signs of water intrusion.
- Weather seal damage (if equipped).
- Bent terminals.
- Overheating due to a poor connection (terminal may be discolored due to excessive current draw).
- Terminals that have been pushed back into the connector cavity.
- Check for spread terminals and verify proper terminal tension.
Repair any conditions that are found.
- Connect all PCM-1 harness connectors. Be certain that all harness connectors are fully seated and the connector locks are fully engaged.
- Connect all in-line harness connectors (if equipped). Be certain that all connectors are fully seated and the connector locks are fully engaged.
- Connect all related component harness connectors. Be certain that all connectors are fully seated and the connector locks are fully engaged.
- With the scan tool, erase DTCs.
- Test drive or operate the vehicle in accordance with the when monitored and set conditions.
- With the scan tool, read DTCs.
Did the DTC return?
Yes
- Replace and program the Powertrain Control Module 1 (PCM-1) in accordance with the Service Information. Refer to MODULE, POWERTRAIN CONTROL (PCM), REMOVAL AND INSTALLATION .
- Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
No
- Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
- Test complete.
