SUBJECT:
H633 ECU UPDATE - CAMPAIGN CLOSE
We thank you for your cooperation and patience the past 18 months during the implementation of the H620 and H633 campaigns. Your efforts have assured the success of the program which has resulted in modifying the maximum number of vehicles with a limited supply of available ECUs.
Effective with repairs completed by March 14, 1992, RRNA will end the ECU update campaign H633 and the ECU exchange process begun with campaign H620. No H633 claims will be accepted for repairs performed after March 14, 1992.
IMPORTANT - CALIFORNIA DEALERS:
Recall D632 (California only) will continue with no change. Lucas will continue to update and exchange unmodified ECUs (part numbers PRC8747 and PRC7081) returned by California dealers.
Unmodified Vehicles
Approximately 80% of eligible vehicles have been modified. An unmodified vehicle with a "false" check engine light or A/C "cutout" problem may still be repaired. Submit a warranty claim as follows:
Repair Code 7G1U
Labor Operation 192234
Part Number PRC9060R (you must be replacing a
PRC7081 or PRC8747)
"Float" ECUs
We will contact you shortly regarding the return of your "float" ECU(s) provided at no charge.
