S S t t e e p p 3 3 - Car's engine does not die.
1.
Unplug the large 4-pin Molex connector while the car's engine is running. If it
dies, replace the CPU. If the car stays running, the proper ignition wire was not
interrupted. Recheck the connections for ignition.
S S t t e e p p 4 4 - Valet code does not work.
1.
Test the valet code and switch operation. Enter programming mode using the
valet switch. If the system enters programming mode, the switch and valet code
are in operating order. If not, perform the following tests:
2.
Check the WHITE/BROWN wire, ignition input is on and verify that it shows
+12V when the ignition is turned ON and +0V when the ignition is OFF. If not,
refer to the sections Ignition Immoblizer and Starter Immobilizer.
3.
Test the WHITE wire at the control unit connector. It should rest at 5 volts. When
pressing the marked side, it should read 3 volts and when pressing the
unmarked side it should read 0 volts. If any reading is incorrect, move the
voltmeter to the BLACK wire at the valet switch. It should read 0 volts at rest, 0
volts when the marked side marked is pressed, and 0 volts when the unmarked
side is pressed. If the BLACK wire tests correctly and the WHITE wire does not,
replace the switch. If the BLACK wire tests incorrectly, repair the ground circuit.
If both wires test correctly, then the valet code has been changed. Use the
CliffNet Wizard Pro to reset the valet code.
