Gauges - Testing & Troubleshooting

  1. Check the ECON switch (A) according to the table.

NOTE:

  • When an LED is located between terminals, check if the LED illuminates by connecting power and ground to the LED.
  • Note this important operating characteristic; diode bias causes a diode to fully conduct electricity in one direction (forward), while not at all in the opposite direction (reverse).

  • Before testing, do the gauge control module self-diagnostic function, and make sure the B-CAN communication lines are OK.
  • If you are troubleshooting multiple DTCs, be sure to follow the instructions in B-CAN System Diagnosis Test Mode A - Refer to: Body Electrical Troubleshooting - B-CAN System Diagnosis Test Mode A - Initial Communication and DTC Checks,.
  • Before testing, make sure the No. B21 (10 A) fuse in the under-hood fuse/relay box is OK.
  • Before testing, make sure the No. C34 (7.5 A) fuse in the under-dash fuse/relay box is OK.
