For example, activate turn signals or wipers. 4.- Read at the BCM diagnosis session if BCM is receiving information from SCCM. Through diagnosis review if activation from horn, wipers or turn signal is requested and are working. 5.- Disconnect the SCCM fuse for around 30s,and repeat the previous steps to see if failure still present. 6.- Do a hard reset to BCM and evaluate if any DTC is set. Retest if failure still present. 7.- Before replacing the SCCM disconnect it and reconnect it again. If there are no DTC's active, physical defects, steering controls inop, wipers inop, nor turn signal inop, horn inop, then SCCM does not need to be replaced.
