TEST ACTION APPLICABILITY
3 Disconnect the TIP Solenoid harness connector.
Turn the ignition on.
Using a 12-volt test light connected to ground, probe the (F12) Fused Ignition Switch
Output circuit.
Does the test light illuminate brightly?
All
Yes → Go To 4
No → Repair the (F12) Fused Ignition Switch Output circuit.
Perform POWERTRAIN VERIFICATION TEST VER-5-NGC.
4 Turn the ignition off.
Disconnect the TIP Solenoid harness connector.
Disconnect the PCM harness connectors.
Turn the ignition on
Measure the voltage of the (K55) TIP Sol Control circuit in the TIP Solenoid harness
connector.
Does the voltmeter indicate any voltage present?
All
Yes → Repair the short to voltage in the (K55) TIP Sol Control circuit.
Perform POWERTRAIN VERIFICATION TEST VER-5-NGC.
No → Go To 5
5 Turn the ignition off.
Disconnect the TIP 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 (K55) TIP Sol Control circuit from the TIP 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 (K55) TIP Sol Control circuit.
Perform POWERTRAIN VERIFICATION TEST VER-5-NGC.
6 Turn the ignition off.
Disconnect the TIP Solenoid harness connector.
Disconnect the PCM harness connectors.
Measure the resistance between ground and the (K55) TIP Sol Control circuit at the
TIP Solenoid harness connector.
Is the resistance below 100 ohms?
All
Yes → Repair the short to ground in the (K55) TIP Sol Control circuit.
Perform POWERTRAIN VERIFICATION TEST VER-5-NGC.
No → Go To 7
7 NOTE: Before continuing, check the PCM harness connector terminals for
corrosion, damage, or terminal push out. Repair as necessary.
If there are no possible causes remaining, view repair.
All
