Reading and Clearing Diagnostic Trouble Codes

Special Tools





The ECU incorporates Fault Recovery Strategies to minimize the effect of a system failure. A serial data link is provided to allow diagnostic information to be retrieved using Land Rover's Testbook diagnostic equipment (a required special tool). This is also used to set height sensor specifications when required.

Note that the serial link connector is colored black for identification purposes. Any faults stored in the ECU memory, from the previous or current running period will cause the ECU to flash the RAISE and LOWER lamps for 30 sec. followed by continuous illumination. If the ECU registers a system fault it will store the fault in the memory.
