SERVICE INFORMATION

Due to impending changes in specifications of the Electronic Control Unit, it is necessary to modify the feedback monitor tester, P/N YWB 120 (Lucas #60973066), in order that the feedback check procedures on both the current ECU's (DAC 1926, DAC 2597) and the latest ECU (DAC 411S), can be carried out.

It will be necessary to return all feedback monitors to Leonia in order to have the modifications carried out by Lucas Industries.

Please be advised of the procedure for returning units for modification by the respective Zone Service Departments. Do not send monitors to Leonia until instructed by your Zone.

Feedback monitors will be returned after modification with label instructions for checking all XJ-S vehicles. The modified tester will carry a new part number, YWB 130.
