U0155 HONDA - F-CAN Malfunction Gauge Control Module-Powertrain Control Module
U0155 HONDA Possible Causes
- Faulty Gauge Control Module
- Gauge Control Module harness is open or shorted
- Gauge Control Module circuit poor electrical connection
- Faulty Powertrain Control Module (PCM)
How is the U0155 HONDA code repair?Start by checking the "Possible Causes" listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector's pins.
Keep in mind, some systems (like audio and navigation with volatile memory) will lose all stored data when you disconnect the battery. So make sure you’ve got the anti-theft codes and write down the audio presets before doing that.
What is the cost to diagnose the U0155 HONDA code
Labor: 1.0The cost to diagnose the U0155 HONDA code is 1.0 hour of labor. The auto repair labor rates vary widely across the country, and even within the same city. Most auto repairs shops charge between $75 and $150 per hour.
When is the code detected?The U0155 code is set when the Powertrain Control Module (PCM) does not receive any signals via the F-CAN lines for at least 1 second.
- Engine Light ON (or Service Engine Soon Warning Light)
U0155 HONDA MeaningThe Controller Area Network (CAN) transmits/receives pulsing signals to/from the control modules simultaneously by using two signal lines (CANH and CANL). When the Powertrain Control Module (PCM) does not receive the signals from the Gauge Control Module via the F-CAN lines for a set time, the PCM detects a malfunction and stores a Diagnostic Trouble Code (DTC).
