Bendix EC-60 UDS 102 / SPN 1808 FMI 2 — YRS Static BITE Error

Code Details

Plain-English Meaning

The EC-60 recorded a static BITE (built-in test equipment) failure from the yaw rate sensor. Static BITE runs during the sensor's power-up sequence while the vehicle is stationary, checking internal electronics and initial signal validity before allowing the sensor to participate in ESP calculations. A static BITE failure means the sensor's own self-test has detected a condition it cannot validate — this category of fault typically points to internal sensor degradation rather than an external wiring or calibration problem.

The Bendix EC-60 table maps UDS code 102, blink code 22-06, J1587 103-02, and J1939 SPN 1808 FMI 2 to this ABS/ATC/ESP diagnostic entry. The Bendix source indicates an ABS and/or ATC/ESP warning lamp can be on for this entry. The EC-60 continuously monitors wheel speed sensor circuits, pressure modulation valve output drivers, supply voltage quality, J1939 network data from the engine and transmission controllers, and internal self-diagnostic routines. When any monitored value falls outside its acceptable range — or a circuit does not respond as the module expects — the EC-60 logs a diagnostic trouble code and may disable the affected ABS, ATC, or ESP function. Bendix ACOM Pro or a compatible diagnostic interface is the required tool for reading live sensor data, running actuator tests, performing calibrations, clearing latched codes, and adjusting EC-60 configuration parameters. Generic J1939 scan tools can read the SPN/FMI but cannot access EC-60-specific live data screens or configuration settings.

Common Symptoms

• ESP/stability lamp on
• ESP suspended — the EC-60 rejects YRS data when the sensor's internal self-test fails
• ABS and ATC continue to operate normally through their own separate signal paths
• Code typically present at every key-on rather than only under specific driving conditions
• No recent wiring work, connector issue, or calibration event that would explain the fault

Possible Causes

Possible causes may include the items below. The list is not a parts diagnosis.

• YRS internal electronics have degraded to the point where the power-up self-check cannot pass
• Moisture intrusion into the sensor housing has damaged internal circuit boards or MEMS elements
• Age or temperature cycling has caused internal component failure in the sensor's oscillator or signal processor
• Previous impact or heat event that damaged internal sensor components
• Manufacturing defect in the sensor that has progressed over time to the point of causing self-test failure

First Checks

• Verify that the YRS connector and supply wiring are clean and properly connected before assuming internal sensor failure — a marginal power supply can cause self-test failures in some sensor designs.
• Measure YRS supply voltage at the sensor connector with engine running; confirm it is within the sensor's operating range.
• Check CAN bus integrity to the sensor — noise on the sensor CAN bus can interfere with the sensor's internal diagnostics in some implementations.
• If the fault appears at every power-up with correct supply voltage and clean wiring, the sensor's internal hardware has most likely reached the end of its serviceable life.
• Sensor replacement is typically the resolution once power supply and wiring have been confirmed clean — internal BITE failures cannot be corrected externally.

Can I Keep Driving?

A stability sensor fault (yaw rate, steering angle, or lateral acceleration) disables ESP stability intervention while leaving ABS and ATC intact. The vehicle handles as it would without electronic stability control. Drive with that in mind — cornering, evasive maneuvers, and braking on slippery surfaces carry a higher risk. Stability sensor faults should be addressed before returning the vehicle to regular line-haul or severe-weather service.
