READ FAULTS Mode

This function allows the user to read and erase fault codes. A fault counter will appear along with fault displayed on DRB-II. For example, DRB-II will display 1 OF 4 FAULTS. PCM will store up to 8 fault messages. Faults are numbered in reverse order of their setting. The most recent fault to occur will be number one. Vehicles without A/C will always have A/C CLUTCH RELAY CKT (circuit) stored in memory. This fault will always be number one if vehicle is not equipped with A/C. If no fault messages are stored, DRB-II will display NO FAULTS DETECTED and start counter will show 0 STARTS SINCE ERS.

A start counter will appear below DRB-II fault counter display. Start counter counts number of times vehicle has started since fault(s) were set, erased or battery was disconnected. This helps determine if fault is intermittent. Memory space limits start counter to first 3 faults. Start counter of zero equals a hard fault. Start counter number more than one indicates an intermittent fault. Start counter will count up to 255 starts. If no fault messages are stored, DRB-II will display NO FAULTS DETECTED and start counter will show 0 STARTS SINCE ERS.
