  1. Disconnect the e46 ecu connector.
  2. Disconnect the a9 ecm connector.
  3. Measure the resistance of the wire harness side connectors.

Standard resistance




  1. Check transponder key ecu (operation)

  1. Temporarily replace the transponder key ecu with a new or normally functioning one.
  2. Check that then engine starts normally.

Ok: engine starts normally.

System description
System description Hint: The skid control ecu forms a single unit with the abs and traction actuator. Abs (anti-lock brake system): the abs helps prevent the wheels from locking when the brakes are applied firmly or on a slippery surface. Operation description: the skid ...

Throttle / pedal position sensor
Hint: These dtcs relate to the accelerator pedal position (app) sensor. Description Hint: This etcs (electronic throttle control system) does not use a throttle cable. The app sensor is mounted on the accelerator pedal bracket and has 2 sensor circuits: vpa (main) and vpa2 (sub). This ...

Srs warning light remains on
Description The srs warning light is located on the combination meter. When the srs is normal, the srs warning light comes on for approximately 6 seconds after the ignition switch is turned from off to on, and then goes off automatically. If there is a malfunction in the srs, the srs warni ...
