Causes
- Internal CPU or PCB failure inside the control module (ECM/PCM/TCM)
- Corrupted or failed module firmware/software (failed reflash)
- Poor or intermittent power supply (battery, ignition-switched power)
- Bad ground or high resistance ground connection to the module
- Corroded, damaged, or loose module connector pins or wiring harness
- CAN/LIN network short, open, or excessive noise interfering with module operation
Symptoms
- Malfunction Indicator Lamp (MIL) illuminated
- Stored P0606 code (may be accompanied by other P060x or communication codes)
- Loss of communication with the affected control module on a scan tool
- One or more drivability issues (no start, stall, limp mode) depending on which module is affected
- Random or multiple unrelated DTCs set
- Some vehicle functions controlled by the module inoperative or erratic
What to check
- Connect a calibrated scan tool and read all stored/active codes and freeze-frame data
- Verify ability to communicate with the suspected module; note whether it responds, times out, or is missing from the network
- Check battery voltage with engine off and key on (should be ~12.0–12.6 V at rest, higher when charging) and ensure battery is charged
- Visually inspect module, connector, and harness for corrosion, water intrusion, damaged wires, or pin damage
- Perform continuity and resistance checks for module power and ground circuits (verify ignition-switched power and constant battery feed where applicable)
- Inspect and test vehicle network (CAN/LIN) for short to ground/voltage or excessive resistance; monitor bus with oscilloscope if available
Signal parameters
- Module battery/ignition supply: approximately battery voltage with key ON (typical 11–14.5 V)
- Module ground: near 0 V; continuity to chassis ground expected
- CAN bus idle: each CAN line typically around mid-supply at rest (~2.5 V on high/low lines); differential signal present during communication
- Serial/LIN/K-line: idle and active voltages vary by system—verify against manufacturer specs
- Module wake/sleep signal states: verify correct levels per vehicle documentation
Diagnostic algorithm
- Record all codes and freeze-frame data. Confirm P0606 is current or historic and note any accompanying codes. 2) Verify battery state of charge and charging system health; fully charge battery before extended diagnostics. 3) Confirm scan tool can communicate with the suspect module; if module not present on network, focus on power/ground and bus wiring. 4) Visually inspect module connector and harness for water, corrosion, or damage; repair any wiring faults found. 5) Measure supply voltage and ground at the module connector with key ON and engine OFF; repair any power/ground issues. 6) Check CAN/LIN bus continuity and voltages; use an oscilloscope to look for noise or missing frames if communication is intermittent. 7) Attempt to clear the code and re-scan; if code returns immediately and communication is present, try a manufacturer-directed software reflash/update and follow security/procedure steps. 8) If software update fails or the module refuses to reflash, or if internal hardware faults are indicated, prepare for module replacement. 9) If module replacement is required, program the new module per manufacturer procedures, including immobilizer/anti-theft pairing, adaptations, and relearns. 10) After repair, clear codes and perform full system verification and road test; monitor for reoccurrence.

100%
Causes
- Internal CPU or PCB failure inside the control module (ECM/PCM/TCM)
- Corrupted or failed module firmware/software (failed reflash)
- Poor or intermittent power supply (battery, ignition-switched power)
- Bad ground or high resistance ground connection to the module
- Corroded, damaged, or loose module connector pins or wiring harness
- CAN/LIN network short, open, or excessive noise interfering with module operation
Symptoms
- Malfunction Indicator Lamp (MIL) illuminated
- Stored P0606 code (may be accompanied by other P060x or communication codes)
- Loss of communication with the affected control module on a scan tool
- One or more drivability issues (no start, stall, limp mode) depending on which module is affected
- Random or multiple unrelated DTCs set
- Some vehicle functions controlled by the module inoperative or erratic
What to check
- Connect a calibrated scan tool and read all stored/active codes and freeze-frame data
- Verify ability to communicate with the suspected module; note whether it responds, times out, or is missing from the network
- Check battery voltage with engine off and key on (should be ~12.0–12.6 V at rest, higher when charging) and ensure battery is charged
- Visually inspect module, connector, and harness for corrosion, water intrusion, damaged wires, or pin damage
- Perform continuity and resistance checks for module power and ground circuits (verify ignition-switched power and constant battery feed where applicable)
- Inspect and test vehicle network (CAN/LIN) for short to ground/voltage or excessive resistance; monitor bus with oscilloscope if available
Signal parameters
- Module battery/ignition supply: approximately battery voltage with key ON (typical 11–14.5 V)
- Module ground: near 0 V; continuity to chassis ground expected
- CAN bus idle: each CAN line typically around mid-supply at rest (~2.5 V on high/low lines); differential signal present during communication
- Serial/LIN/K-line: idle and active voltages vary by system—verify against manufacturer specs
- Module wake/sleep signal states: verify correct levels per vehicle documentation
Diagnostic algorithm
- Record all codes and freeze-frame data. Confirm P0606 is current or historic and note any accompanying codes. 2) Verify battery state of charge and charging system health; fully charge battery before extended diagnostics. 3) Confirm scan tool can communicate with the suspect module; if module not present on network, focus on power/ground and bus wiring. 4) Visually inspect module connector and harness for water, corrosion, or damage; repair any wiring faults found. 5) Measure supply voltage and ground at the module connector with key ON and engine OFF; repair any power/ground issues. 6) Check CAN/LIN bus continuity and voltages; use an oscilloscope to look for noise or missing frames if communication is intermittent. 7) Attempt to clear the code and re-scan; if code returns immediately and communication is present, try a manufacturer-directed software reflash/update and follow security/procedure steps. 8) If software update fails or the module refuses to reflash, or if internal hardware faults are indicated, prepare for module replacement. 9) If module replacement is required, program the new module per manufacturer procedures, including immobilizer/anti-theft pairing, adaptations, and relearns. 10) After repair, clear codes and perform full system verification and road test; monitor for reoccurrence.
