TEST ACTION APPLICABILITY
3 Turn the ignition off.
Disconnect the Power Steering Pressure Switch harness connector.
Disconnect the PCM harness connector(s).
Measure the resistance between ground and the (K10) PSP Switch Signal circuit at
the Switch connector.
Is the resistance below 100 ohms?
All
Yes ! Repair the short to ground in the (K10) PSP Switch Signal circuit.
Perform POWERTRAIN VERIFICATION TEST VER - 2 - NGC.
No ! Go To 4
4 Turn the ignition off.
Disconnect the Power Steering Pressure Switch harness connector.
Disconnect the PCM harness connector(s).
CAUTION: DO NOT PROBE THE PCM HARNESS CONNECTORS. PROBING
THE PCM HARNESS CONNECTORS WILL DAMAGE THE PCM TERMINALS
RESULTING IN POOR TERMINAL TO PIN CONNECTION. INSTALL
MILLER SPECIAL TOOL #8815 TO PERFORM DIAGNOSIS.
Measure resistance of Power Steering (K10) PSP Switch Signal circuit from the
Power Steering Pressure Sensor harness connector to the appropriate terminal of
special tool #8815.
Is the resistance below 5.0 ohms?
All
Yes ! Go To 5
No ! Repair the open in the (K10) PSP Switch Signal circuit.
Perform POWERTRAIN VERIFICATION TEST VER - 2 - NGC.
5 Turn the ignition off.
Disconnect the Power Steering Pressure Switch harness connector.
Ignition on, engine not running.
Connect a Jumper Wire to the (K10) PSP Switch Signal circuit at harness connector.
Using the DRBIIIt, while monitoring the Power Steering Pressure Switch.
Touch the Jumper Wire to the Ground circuit at the Power Steering Pressure Switch
harness connector several times.
Did the Power Steering Pressure Switch status change from Hi to Low?
All
Yes ! Replace the Power Steering Pressure Switch.
Perform POWERTRAIN VERIFICATION TEST VER - 2 - NGC.
No ! Go To 6
6 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
Repair
Replace and program the Powertrain Control Module in accordance
with the Service Information.
Perform POWERTRAIN VERIFICATION TEST VER - 2 - NGC..
