Service Bulletin: R: S: P: M: D: V

This service bulletin from MCFE BV addresses an issue with replacing old throttle sensors in some truck models. When replacing the old throttle sensor RL450538 with a new one RL635131, the "Low Pot" signal is missing and an alarm occurs, preventing the truck from moving. The solution is to add the "Low Pot" signal wire using an extra harness RL636090. Instructions and diagrams show how to connect the Low Pot wire to terminals to restore functionality.

Throttle sensors in trucks with ZAPI SEM controllers

DESCRIPTION:
The “Low Pot” signal is missing when replacing the new throttle sensor. Alarm code “Pedal wire KO” will occur in some
older models and the truck will not move.

ACTIONS:
When replacing old throttle sensor RL450538 (Hardellet) with RL635131 (Frei), the “Low Pot” signal has to be added by
using extra wire harness RL636090. See pictures 1, 2 and the circuit diagram in picture 3!
