READING CODES
To accurately diagnose the Computer Command Ride (CCR) system, the CCR Diagnostic System Check must he performed before proceeding with any other testing. Diagnostic System Check

This method does not require any disassembly. First, connect a jumper between DLC terminals 3 and 4. Then, turn the ignition switch to the "RUN" position. This places the controller in a "Blink Codes" mode, and will cause any error codes stored in the controller to be displayed by the driver switch L.E.D.'s. The Blink Codes sequence starts with a short lamp off period. Then, code 12 is displayed three times to mark the beginning of the sequence. Next, each stored error code is blinked out in ascending order. Each error code is displayed three times before proceeding to the next code. After all error codes have been displayed, the entire sequence will begin again by displaying code 12 three times. This will continue until the jumper between pins 3 and 4 of the DLC has been removed. An example of an error code format is shown in image (code 23 stored).
