Troubleshooting Hints
Perform the following procedure before you begin the System Diagnosis:
- If the vehicle does not crank, the PASSLOCKā¢
is not at fault. Refer to Engine Controls.
- Cycle the ignition switch to RUN, with the engine OFF, in order
to inspect the bulb function of the theft deterrent indicator.
If the indicator does not flash after the vehicle has stalled, then
the PASSLOCKā¢ System has not been engaged and is not at fault. Refer
to
Powertrain On Board Diagnostic (OBD) System Check
in Engine Controls-2.2L or
Powertrain On Board Diagnostic (OBD) System Check
in Engine Controls-2.4L.
- Visually inspect the following components:
- If multiple indicators light continuously, inspect for a loss
of serial data. Refer to
Data Link Connector Schematics
.
- Inspect for engine diagnostic trouble codes (DTCs). Refer to Engine
Controls.
- Inspect for a broken or partially broken wire inside the insulation.
A broken wire can cause system malfunction but prove to be G in a continuity/voltage
test with a system disconnected. These circuits may be intermittent or resistive
when loaded. Inspect the circuits by monitoring for a voltage drop with the
system operational under a load.
- Inspect for the proper installation of aftermarket electronic
equipment which may affect the integrity of other systems. Refer to
Checking Aftermarket Accessories
in Wiring Systems.
System Diagnosis
Perform the Diagnostic System Check. Refer to the Symptom Table for
the appropriate diagnostic procedures.
