The signal voltage of the additional accelerator sensor is higher than 4.3 V. The wire connecting to the ground point is broken, the signal wire is shorted to a wire with a higher voltage, the sensor or the idle speed switch of the additional accelerator is faulty.

The signal voltage from the auxiliary accelerator sensor is below 0.4 V. The power or signal wire is broken. The sensor is faulty. The contacts in the connectors are corroded or damaged.

The idle speed switch signal is missing between 0 and 13 percent. The signal or power wire is broken. The signal wire is shorted to power or ground. The idle speed switch for the auxiliary accelerator is faulty. The contacts in the connectors are damaged or corroded.

The BBM unit cannot communicate with other control units via the SAE J1939 data channel. There is a break in the data channel wires between the BBM unit and other control units, or a short to ground or power in the data channel wires. The BBM unit may be faulty.

Software failure or faulty memory chip in the ECM unit. Reprogram the ECM unit; if the problem persists, replace the ECM unit.

The VBM unit receives incorrect messages via the SAE J1708 data channel. Partial damage to the data channel wires.

There was an error during programming or the memory chip in the ECM unit is faulty. Reprogram the ECM unit. If the problem persists, replace the ECM unit.

Error in stored data. Incorrect software or faulty memory chip in the ECM unit. Reprogram the ECM unit. If the problem persists, replace the ECM unit.
