TEST 6A - Diagnosing Compass/Mini-Trip Module Faults
NOTE:
For connector terminal identification, see CONNECTOR IDENTIFICATION . For appropriate wiring diagram, see WIRING DIAGRAMS .
- Turn ignition switch to ON position. If compass/mini-trip screen is blank, perform TEST 6B. If compass/mini-trip screen displays "OC" or "SC", perform TEST 7A. If compass/mini-trip screen does not display "OC" or "SC", actuate field strength test using DRB-II.NOTE: On compass/mini-trip screen, number 8 normally follows a letter; however, a reading can be 0-15.
- If compass/mini-trip screen does not display "N8," "W8" and then "D1," replace compass/mini-trip module. Perform VERIFICATION TEST - VERIFICATION OF REPAIRS . If compass/mini-trip screen displays "N8," "W8" and then "D1," actuate internal test using DRB-II.
- If compass/mini-trip screen does not display a blank screen and then "2", replace compass/mini-trip module. Perform VERIFICATION TEST - VERIFICATION OF REPAIRS . If compass/mini-trip screen displays a blank screen and then "D2," actuate "VF" display test using DRB-II.
- All compass/mini-trip screen segments should light and then "D3" should be displayed. If compass/mini-trip does not function as specified, replace compass/mini-trip module. Perform VERIFICATION TEST - VERIFICATION OF REPAIRS . If all compass/mini-trip screen segments light and then "D3" is displayed, read compass/mini-trip faults using DRB-II.
- If any fault messages exist, replace compass/mini-trip module. Perform VERIFICATION TEST - VERIFICATION OF REPAIRS . If no fault messages exist, check for a compass/mini-trip illumination problem. If a problem exists, perform TEST 28A. If a problem with compass/mini-trip illumination does not exist, check if ECO (average MPG) is inoperative or wrong. If a problem exists with ECO (average MPG), perform TEST 8A.
- If no problems exist with ECO (average MPG), check if ECO (MPG) is inoperative or wrong. If a problem exists with ECO (MPG), perform TEST 8A. If no problems exist with ECO (MPG), check if "ET" (elapsed time) is inoperative. If a problem exists with "ET," perform TEST 9A. If no problems exist with "ET", check if trip odometer is inoperative or wrong.
- If a problem exists with trip odometer, replace compass/mini-trip module. Perform VERIFICATION TEST - VERIFICATION OF REPAIRS . If no problems exist with trip odometer, perform TEST 36A. TEST 36A is for inoperative or inaccurate DTE (distance to empty) only.
