You have a problem within the universal theft deterrent system

PASS-KEY II(R) SYSTEM TESTING
NOTE:To prevent misdiagnosis, check for diagnostic trouble codes. See appropriate TESTS W/CODES article in ENGINE PERFORMANCE section. Refer to menu below.

For 3.8L, see TESTS W/CODES - 3.8L
For 5.7L, see TESTS W/CODES - 5.7L
NOTE:SECURITY indicator will remain illuminated for one minute after PASS-KEY II(R) system fault has been repaired.

Engine Does Not Crank, SECURITY Indicator Illuminates For About 5 Seconds, Then Goes Out
Disconnect theft deterrent relay connector. Connect test light between theft deterrent relay connector terminal A1 (Yellow/Black wire) and battery voltage. Observe test light and turn ignition switch to START position.
If test light does not illuminate, check for poor connection, open or short to voltage in Yellow/Black wire. If Yellow/Black wire is okay, replace Body Control Module (BCM). If test light illuminates, connect test light between theft deterrent relay connector terminal C2 (Brown wire) and ground. On A/T models, place transmission in Park or Neutral. On M/T models, depress clutch pedal. On all models, observe test light and turn ignition switch to START position.
On A/T models, if test light does not illuminate, check for an open in Brown wire between theft deterrent relay and transmission range switch. Check for an open or poor connections in transmission range switch. Check for open in Yellow wire between transmission range switch and ignition switch.
On M/T models, if test light does not illuminate, check for an open in Brown wire between theft deterrent relay and clutch start switch. Check for an open or poor connections in clutch start switch. Check for open in Yellow wire between clutch start switch and ignition switch.
On all models, if test light illuminates, connect test light between theft deterrent relay connector terminal C1 (Yellow wire) and ground. Observe test light and turn ignition switch to START position.
If test light does not illuminate, check for open in Yellow wire between theft deterrent relay connector terminal C1 and splice. If test light illuminates, connect 30-amp fused jumper wire between theft deterrent relay connector terminals C1 (Yellow wire) and A2 (Purple wire). Turn ignition switch to START position.
If engine does not crank, diagnose problem with starting or charging system. See procedures in the GENERATOR & REGULATOR or STARTER article in ELECTRICAL section. If engine cranks, check for poor connections at theft deterrent relay. If connections are okay, replace theft deterrent relay. Also, check for short in Purple wire between theft deterrent relay and starter solenoid. A short in Purple wire may cause theft deterrent relay to fail.
Engine Cranks But Will Not Start, SECURITY Indicator Illuminates For About 5 Seconds, Then Goes Out
Disconnect Body Control Module (BCM) 32-pin connector C3 (Blue). Turn ignition switch to RUN position. Using DVOM, measure voltage between BCM connector C3, terminal D8 (Dark Blue wire) and ground. If about 5 volts is not present, go to next step. If about 5 volts is present, go to step 3).
Check for open or short in Dark Blue wire between BCM and Powertrain Control Module (PCM). Also, check for poor connections at BCM and PCM. If Dark Blue wire and connections are okay, check for related codes stored in PCM. See appropriate TESTS W/CODES article in ENGINE PERFORMANCE section.
For 3.8L, see TESTS W/CODES - 3.8L
For 5.7L, see TESTS W/CODES - 5.7L
Turn ignition switch to OFF position. Reconnect BCM connector. Turn ignition switch to RUN position. Using DVOM, measure voltage between BCM connector C3, terminal D8 (Dark Blue wire) and ground. If about 2.5 volts is not present, check for poor connections at BCM. If connections are okay, replace BCM. If about 2.5 volts is present, check for related codes stored in PCM. See appropriate TESTS W/CODES article in ENGINE PERFORMANCE section.
For 3.8L, see TESTS W/CODES - 3.8L
For 5.7L, see TESTS W/CODES - 5.7L
