Causes

Faulty chassis control module (CCM)
Loss of power or ground to the CCM
Open, shorted, or intermittent wiring on the CAN/data bus
Faulty gateway/module on the same data network
Blown fuse or poor connector at CCM
Corroded or damaged connector pins

Symptoms

Warning lights related to chassis systems (ABS, traction, stability) or general communication warnings
Loss or intermittent operation of chassis features (suspension, steering assist, stability control)
Multiple communication-related DTCs present
Inability to communicate with CCM using a scan tool or intermittent responses
Melted, burnt, or corroded connectors near CCM

What to check

Connect a capable scan tool and attempt to read the CCM; note additional DTCs and freeze frame data
Confirm battery voltage is stable (12.4–14.8 V) with ignition on and during cranking where required
Check fuses and relays related to the CCM power/IGN feed
Visually inspect CCM connectors and harness for corrosion, damaged pins, or water intrusion
Observe the CAN/data bus for presence of other modules and message traffic
Check for intermittent faults by wiggling harness with scanner connected

Signal parameters

CAN bus voltage (dominant and recessive levels)
Message ID presence and frequency from CCM (messages/sec or Hz)
Bus error counters (Tx/Rx errors) reported by scan tool
Module supply voltage and ground continuity
Bus termination resistance (should measure ~60 Ω across CAN H and CAN L with key off on two-wire CAN)
Time since last valid message from CCM

Diagnostic algorithm

Read all stored and pending DTCs from all modules; record freeze frame and network-related codes.
Verify battery state of charge and charging system health; recharge or replace battery if low.
Check relevant fuses/relays and verify CCM has proper power and ground at the connector with key on.
With a scan tool, observe CAN bus traffic. Confirm whether CCM appears on the bus and note message IDs and frequency.
Inspect CCM connector for bent/missing pins, corrosion, water intrusion, or repair splices. Repair any physical damage.
Measure CAN H/L voltages and termination resistance. Look for shorts to battery or ground and unexpected low/high resistance.
Wiggle harness and connectors while monitoring communication to find intermittent faults.
Isolate sections of the bus if necessary (disconnect peripherals or modules) to identify a shorting node or noisy device.
If wiring and power/ground are good, check for available module software updates and reflash/configure per OEM procedures.
If communication remains lost and wiring/power are verified, consider replacing the CCM with a known-good unit and program/configure as required.
After repairs, clear DTCs and perform a thorough road test and network scan to verify stable operation.

Likely causes

Loose or corroded connector at CCM
CAN bus short to battery or ground near CCM
Failed CCM internal electronics
Missing termination resistor or incorrect bus wiring after repairs
Low battery voltage or charging system issue causing module to drop off bus

Fault status

⚠️ Status

Communication fault: CCM not responding or reporting bus errors. Check power/ground, connectors, and CAN bus integrity; may require module reprogramming or replacement.

🟡 Repair difficulty: Medium

⏱️ Diagnostic time: 1.0-3.0 hours
