Electronic instrument clusters contain an odometer memory chip to record the vehicle mileage. Since the chip is relatively small and delicate, certain care
must be exercised in handling the device during cluster or chip service. Refer to the procedure below for proper memory chip removal and installation
procedures.
DIAGNOSIS
Prior to servicing the instrument cluster, utilize the "Self-Diagnostic Test" procedure provided in the service manual to determine whether the cluster or
the memory chip is faulty.
^
A code of 1, 2 or 3 during the first test and the word "Fail" displayed in the odometer area, indicates the cluster is defective. Replace the cluster,
retaining the memory chip for installation in the replacement cluster so as to maintain the vehicle mileage. This electronic memory device contains
the current accumulated vehicle mileage. Follow the procedure below to transfer the memory chip.
^
A code of "4" and the word "Fail" displayed in the odometer area indicates a probable odometer memory chip failure. Order a replacement chip
package and install per the following instructions.
NOTE:
REPLACEMENT OF THE ODOMETER CHIP IS PERMISSIBLE ONLY WHERE ORIGINAL MILEAGE MAY BE POSTED ON A
DOOR JAMB LABEL. IN AREAS WHERE LAWS REQUIRE ORIGINAL MILEAGE TO BE DISPLAYED IN ODOMETER,
CONTACT HUNTSVILLE ON 1-800-328-6121.
