Easy step by step guide on how to retrieve and define Range Rover OBD1 diagnostic trouble codes.
Difficulty Scale: 2 of 10
Step 1 - When a code is stored the "check engine" light will illuminate. Most of these trouble codes are made up of two digits and are accessible under the passenger seat.
Step 2 - Turn the ignition key to the "ON" position the trouble codes will start to display. The first set of blinking lights will be the "tenth" digit and the second set of blinks tell the "one" position. 
Step 3 - Example, if the first blinking light flashes off and on twice, and the second blinking light flashes once the code number is 21.
Step 4 - To restart code gathering sequence shut the key off and then back on again.

Step 5 - To clear trouble codes after the repairs have been made turn the ignition key to the "on" position, disconnect the serial link mating plug, wait ten seconds and reconnect the plug. Switch the ignition switch to the "off" position for five seconds and turn the ignition key back on again.
