At ~74k mi., my '02 RS just started having the Dash "Security" Light staying lit while I'm driving -- is this just an indication that the security chip on the key is worn/not making good contact?

TIA

 

That means your wife/girlfriend is tracking you...

J/k. After using a blank key cut to match match my old one, my light stays on for several seconds after I start the engine. I'm certain that my pellet matches.

I would imagine, though, that your engine would not start if the security pellet was faulty. If someone had disabled VATS on your car, would the lamp still light?

 

Guess this is becoming my own troubleshooting thread -- just found this, but looks like I need a Tech 2 for this...

Diagnostic System Check - Theft Deterrent

Test Description

The numbers below refer to the step numbers on the diagnostic table.

Lack of communication may be due to a partial malfunction of the class 2 serial data circuit or due to a total malfunction of the class 2 serial data circuit. The specified procedure will determine the particular condition.

The presence of DTCs which begin with "U" indicate some other module is not communicating. The specified procedure will compile all the available information before tests are performed.

Mine turned on one day and never turned off after that. I had it on over a year and it bugged the crap out of me till one day I just removed the light bulb. Lol problem solved. Screw VATTS.

 

Solution, $457.36 later from a dealer shop (luckily 100% covered via extended warranty), was repair the broken wire for the PASS Lock in the Lock Cylinder that was broken, and to address DTC 021 (Body Control Module (BCM)) AKA B21 (yes, OBD Scanners usually don't find these codes), replaced the mechanical ignition lock cylinder and cut new keys.

While I was in, they also replaced a worn passenger wheel hub bearing ($328.80) that made a whirring noise when making gradual left turns.

Prices above are labor & parts...

 

Mine has been on since I bought it 10 years and 100,000 miles ago. I figure it's the lock cylinder, but it's not been an issue yet.

 

^ If you have no other issues, it may just be that broken wire -- could be an easy fix...

 

Here's the details on the DTC 021 (Body Control Module (BCM)) code I had -- I'm not exactly clear how this relates to the Security dash light, however. Anyone have insight? Maybe a result from the broken wire?

DTC 021 and/or 031

Circuit Description

The body control module (BCM) supplies battery voltage to the courtesy lamps through the courtesy lamps supply voltage circuit when the BCM is awake. When the BCM sees the proper inputs it will ground the courtesy lamps low control circuit, and the courtesy lights will illuminate.

Conditions for Running the DTC

The BCM must command the courtesy lamps ON.

Conditions for Setting the DTC

The BCM detects that the output for the courtesy lamps supply voltage circuit is low when it is expected to be high.
There is an open or short to ground in the battery positive voltage circuit to the BCM that feeds the courtesy lamps supply voltage circuit.
The condition above must be present for more than 0.3 seconds.
Action Taken When the DTC Sets

The BCM stores DTC B21/31 in memory.

Conditions for Clearing the DTC

A current DTC B21/31 will clear if a short to ground or open in the courtesy lamps supply voltage circuit is no longer detected by the BCM.
A current DTC B21/31 will clear if the open or short to ground in the battery positive voltage circuit to the BCM that feeds the courtesy lamps supply voltage circuit is no longer present.
A history DTC B21/31 will clear after 100 consecutive ignition cycles if the condition for the malfunction is no longer present and no other BCM faults are detected.
Diagnostic Aids

If the DTC B21/31 is a history DTC, the fault may be intermittent. Refer to Testing for Intermittent and Poor Connections in Wiring Systems.
The following conditions may cause an intermittent malfunction to occur:
An intermittent short to ground or open in the courtesy lamps supply voltage circuit
An intermittent open or short to ground in the battery positive voltage circuit to the BCM that feeds the courtesy lamps supply voltage circuit
An intermittent short to ground in a courtesy lamp
The BCM is intermittently shorted to ground or open
Test Description

The numbers below refer to the step numbers on the diagnostic table.

Test for voltage at the courtesy lamps supply voltage circuit. No voltage at the courtesy lamps supply voltage circuit would indicate that the fault is current, voltage at the courtesy lamps supply voltage circuit would indicate that the fault is intermittent.

Verifies that the COURTESY Fuse is good, an open fuse indicates a short to ground in the courtesy lamps supply voltage circuit or the battery positive voltage circuit of the BCM, that feeds the courtesy lamps supply voltage circuit.

Verifies that the battery positive voltage circuit of the BCM is providing battery voltage.
