TEST ACTION APPLICABILITY
3 Turn the ignition off.
Disconnect the Wastegate Solenoid harness connector.
Using a 12-volt test light connected to battery voltage, probe the (Z1) Ground circuit
in the Wastegate harness connector.
Does the test light illuminate brightly?
All
Yes → Go To 4
No → Repair the (Z1) Ground circuit for an open.
Perform POWERTRAIN VERIFICATION TEST VER-5-NGC.
4 NOTE: The Wastegate Sol Control circuit is a high side control circuit. When
the circuit is operating normally voltage will be present.
Turn the ignition off.
Disconnect the Wastegate Solenoid harness connector.
Disconnect the PCM harness connectors.
Turn the ignition on
Measure the voltage of the (K137) Wastegate Sol Control circuit in the Wastegate
Solenoid harness connector.
Does the voltmeter indicate any voltage present?
All
Yes → Repair the short to voltage in the (K137) Wastegate Sol Control
circuit.
Perform POWERTRAIN VERIFICATION TEST VER-5-NGC.
No → Go To 5
5 Turn the ignition off.
Disconnect the Wastegate Solenoid harness connector.
Disconnect the PCM harness connectors.
CAUTION: DO NOT PROBE THE PCM HARNESS CONNECTORS. PROBING
THE PCM HARNESS CONNECTORS WILL DAMAGE THE PCM TERMI-
NALS RESULTING IN POOR TERMINAL TO PIN CONNECTION. INSTALL
MILLER SPECIAL TOOL #8815 TO PERFORM DIAGNOSIS.
Measure the resistance of the (K137) Wastegate Sol Control circuit from the
Wastegate Solenoid harness connector to the appropriate terminal of special tool
#8815.
Is the resistance below 5.0 ohms?
All
Yes → Go To 6
No → Repair the open in the (K137) Wastegate Sol Control circuit.
Perform POWERTRAIN VERIFICATION TEST VER-5-NGC.
6 Turn the ignition off.
Disconnect the Wastegate Solenoid harness connector.
Disconnect the PCM harness connectors.
Measure the resistance betweenground and the (K137) Wastegate SolControl circuit
at the Wastegate Solenoid harness connector.
Is the resistance below 100 ohms?
All
Yes → Repair the short to ground in the (K137) Wastegate Sol Control
circuit.
Perform POWERTRAIN VERIFICATION TEST VER-5-NGC.
No → Go To 7
