Check Exterior Lights

This warning comes on after starting the car in the dark and driving in the dark for about 3 minutes.
The reason I mention the dark is because quite as you'd expect, if it's not dark out, the lights aren't on and this warning doesn't display.

RE: Check Exterior Lights

Maybe I should also mention another problem.
When I use my remote start to lock/unlock or start my car it used to flash the lights and if locking/unlocking it would also honk. Now when I use it to lock/unlock/start the car no lights flash though after the car starts the lights do come on.
The horn functions as expected.
The remote start unit has a built in relay for the parking light flashing feature.

So basically the lights aren't flashing when I lock/unlock or start the car anymore. Perhaps this is causing the problem with the warning indicator? I wonder if the relay is bad in the starter unit causing a spike/drop in voltage on that circuit.

Can someone tell me the expected current on that circuit so I can see if it's in spec?

RE: Check Exterior Lights

The manual states:

Lamp-Out Warning System (CHECK EXTERIOR LAMPS)

This warning message is displayed when one of the following lamps is turned on and at least one of them is burned out, a stoplamp, rear parking lamp or low beam headlamp. (A high beam headlamp burnout is not monitored.)

Lamp-Out Warning System (CHECK EXTERIOR LAMPS)


Normal Operations

When the lamp outage module detects that its system is operating normally (all lamps are OK), the input on Pin 6 to the message center will be approximately 5900 ohms. When the lamp outage module detects a burned out lamp in its system, it will ground the input on Pin 6 to the message center and the warning will be displayed.

CHECK REFERENCE VOLTAGES AT HARNESS CONNECTOR


Disconnect module.

Check voltage between ground circuit 57 (BK) and the reference circuits of the lamp outage module harness connector. The voltage should be between 10 and 15 volts:

-- With brake pedal pressed, check voltage between Pin 14 (ground Circuit 57 BK) and Pin 13 (left stoplamp reference Circuit 9 LG/O).

-- With brake pedal pressed, check voltage between Pin 14 (ground Circuit 57 BK) and Pin 3 (right stoplamp reference Circuit 5 O/LB).

-- With parking lamps on, check voltage between Pin 14 (ground Circuit 57 BK) and Pin 15 (parking lamp reference Circuit 14 BR).

-- With headlamps on, check voltage between Pin 14 (ground Circuit 57 BK) and Pin 16 (headlamp reference Circuit 13 R/BK).
