Service bulletin B610800

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

losed-circuit Current Measurement. Closed circuit current needs to be measured. Excessive closed-circuit currents may occur continuously or intermittently, and may cause the battery to discharge prematurely. CAUSE The increase in closed-circuit current may be caused by a faulty control unit, or by the installation of a non-approved accessory. INFORMATION In a situation where a vehicle has broken down due to a discharged battery, for diagnostic purposes it is important to not disconnect the battery. This is because a control unit will be reset if the battery is disconnected. Following a reset, the faulty control unit may start functioning correctly again, making accurate diagnosis impossible. To correctly measure closed-circuit current, the 50-amp clip-on probe (previously used with the IMIB) or the 100-amp clip-on probe can now be used in conjunction with the IMIB (Integrated Measurement Interface Box) to properly diagnose closed-circuit current problems over an extended period of time. Connect the amp clip-on probe directly to the IMIB Measurement input 3 (green socket).
