ABS light, gear won't change

If your 2007 Impala is stuck in park and the gear override silver button doesn't work, there may be a few potential problems that are causing the problem. Here are some common causes and troubleshooting solutions you can try: Brake light switch: The most common cause of this problem is a faulty brake light switch. The brake light switch is responsible for sending a signal to the shift interlock solenoid to release the shifter when the brake pedal is depressed and can prevent the shifter from releasing if the switch does not operate properly. Make sure your brake lights work by pressing on the brake pedal. If they don't work, it's probably a brake light switch issue that needs to be replaced. Shift Interlock Solenoid: The shift interlock solenoid is a mechanism that prevents the shifter from moving without pressing the brake pedal If the solenoid is faulty or a blown fuse can cause the shifter to go into park. Check the fuse connected to the shift interlock system and replace if necessary. If the fuse is good, the solenoid may need to be replaced. Shift Cable: The shift cable connects the shifter to the transmission and allows you to change gears. Damaged, loose, or misaligned cables can prevent the shifter from leaving the parking space. Inspect the shift cable for any obvious issues and make sure it is securely attached to the shifter and transmission. Shift lock control module: Some vehicles have a shift lock control module that ensures proper operation of the shift interlock system. Malfunction of this module can cause the problem. It may be necessary to use a diagnostic scan tool to check for any error codes associated with the module. Ignition switch: Faulty ignition under certain conditions

you have fitted a single pole bulb into a two pole socket ,have a good look at the end of the bulb and the look inside socket and you will see what i mean

truck is in limp/safe/limited power mode its a safety due to brake problem check abs sensors the wiring,connections and clips for problems or damage if none visible have truck scanned most auto stores such as auto zone / advanced auto [check your local area]offer this service for free the trouble code will tell u what area or part is causing a problem so a repair can b made

Pop the trunk.

Look at the backside of the tail light area – it’s wide open. Turn the affected light bulb socket to the left. It’ll take some force, but you won’t break it.

Once it unlocks, you can pull the light bulb out.

Push the new bulb in.

Put the socket back into its place by pushing it in, then turning to the right. It’ll lock back into place.

Test the brake light to make sure it works.

make sure you changed the correct bulb (it happens). turn on the other side to be sure. you may also have a defective new bulb (that happen too) lots of cheap electrical parts out there!

Shift interlock solenoid is probably bad. The override is down by the shifter with a little round cap that pops out to push a long narrow screwdriver into the hole.

when brake light is constantly on it normally means the rear brake light dont work (bulb blown) ABS normally means sensors pushed too far or teeth on abs cv axle could be damaged or bent. check that first.

looks like you have a faulty sensor (ABS) check all conections on hubs you may have disturbed something when you changed your brakes hope this helps

Your indicator bulb has blown. If you replace the bulb, you would find it will go back to normal.
