CBC AUTO DRIVE CYCLE DIAGNOSTICS Designed to catch intermittent faults. n Will store up to 32 fault codes in module for one hour after key off. n This test is done by driving car until the ride control warning lamp illuminates or the technician has determined that there is no fault. n If no fault, enter Service Bay Diagnostics n JH
CBC AUTO SERVICE BAY DIAGNOSTICS n Broken down into 3 parts • Auto/Manual Diagnostic Checks - - Is a self check of system. Will say good or bad • Fault Code Display - - Displays codes • Functional Checks - - This test leads you to doing pinpoint tests JH
CBC AUTO SPRING FILL DIAGNOSTICS n Sometimes, Functional Tests will instruct you to perform Spring Fill Diagnostics. • Used to check individual springs JH
