Service Check Connector:





1. Connect the Service Check Connector terminals with the SCS SHORT CONNECTOR.

Malfunction Indicator Lamp:





2. Note the failure code. The Malfunction Indicator Lamp (MIL) indicates a system failure code by its blinking frequency. The MIL can indicate any number of simultaneous component problems by blinking separate codes, one after another. Problem codes 1 through 9 are indicated by individual short blinks. Problem codes 10 through 59 are indicated by a series of long and short blinks. One long blink equals 10 short blinks. Add the long and short blinks together to determine the problem code.
