ZF S6-650

DTC P0833 (6.6L)





Circuit Description
Battery voltage is supplied from the brake fuse to the clutch switch. The clutch switch is a normally closed switch. When the clutch pedal is released, the clutch pedal position switch signal circuit is pulled up to B+. When the clutch pedal is applied, the switch opens, and the voltage drops to 0 volts.

If the engine control module (ECM) detects a specified number of vehicle speed transitions without detecting a clutch switch transition, DTC P0833 sets. DTC P0833 is a type C DTC.

Conditions for Running the DTC
No vehicle speed sensor (VSS) DTC P0500.

Conditions for Setting the DTC
The ECM detects 7 changes in vehicle speed from 0 km/h (0 mph) to above 38 km/h (24 mph) and then back to 0 km/h (0 mph) without the ECM detecting a clutch pedal transition.

Action Taken When the DTC Sets
^ The ECM does not illuminate the malfunction indicator lamp(MIL).
^ The ECM disables cruise control and the power take-off, if equipped.
^ The ECM records the operating conditions when the Conditions for Setting the DTC are met. The ECM stores this information as Failure Records.
^ The ECM stores DTC P0833 in ECM history.

Conditions for Clearing the DTC
^ A scan tool can clear the DTC.
^ The ECM clears the DTC from the ECM history after 40 consecutive warm-up cycles, if no failures are present by this diagnostic or any other non-emission related diagnostic.
^ The ECM cancels the DTC default actions when the ignition switch is OFF long enough in order to power down the ECM.
