Why is my ASR not working in my car?
But the ASR system is tied to all of the electronic systems (EA and LH-SFI) in the car, so everything needs to be working otherwise the car is forced into the “limp-home” mode (LH). Recently, my car developed this problem and this thread is documented as it happened in a daily time format.
What is code 30 for ABS W ASR?
ABS w/ ASR Module: Code 30 – – CAN bus to EA/CC/ISC faulty. LH-SFI Module: No codes. DI Modules: No codes. I removed all of the modules in the F23 box, removed the box frame itself, and inspected all of the wiring to the connectors especially to slots 4/5 (ABS w/ ASR) and 6/7 (EA). All wiring was ‘solid’. Using an ohmmeter, the CAN bus was checked.
Is there an ASR problem on my S500?
All readings ok: 120 ohms across the bus and continuity to all modules on the bus. After re installing the modules, which had all cooled down, the car was started, NO ASR lamp. Ran perfectly. Drove it for about 20 minutes, parked it in the sun (yesterday in SD, it was 95degs).
Where is the ASR light located on an ABS?
But now the ASR light is on. So to kill that, insulate pin 29 on connector 1 of the ABS/ASR [N30/1] module by using a strong but thin tape. The MIL signal comes from this module and lights the ASR lamp located in the IC.

What to do about Bas / ASR warning light?
A faulty front wheel-speed sensor is a common trigger for the BAS/ASR warning light. Even if it isn’t fingered by a DTC, it can’t hurt to clean the front wheel speed sensors and ABS sensor rings anyway. The speed sensors are behind the rotors, held on with Allen screws. Spraying these with electrical contact cleaner can solve the problem.
