Testing reference resistor - RA30001240506X(30-506)

WARNING: This page does not describe the selected car, but rather 42 other vehicles, including the 1999 Mercedes-Benz S600, 1999 Mercedes-Benz S500, 1999 Mercedes-Benz S420, 1999 Mercedes-Benz S320, and 1999 Mercedes-Benz CL600. However, it is still accessible from the selected car via links, so may be relevant.

Tempomat/cruise control (TPM) reference resistor (R29)

Ohmmeter

Resistance values

remove, install (30-566) . Production date (a). Part no. (b), jack designation (c). For several reference resistors there is no jack designation A-G. These reference resistors must be tested as shown on figure at the right.

connect (refer to table).

check (refer to table), replace Tempomat/cruise control reference resistor (R29) if values deviate.
