Overview

Automotive DTC C0080 indicates a potential malfunction in the left rear ABS solenoid #1 circuit causing ABS/traction control issues; generic and ISO/SAE reserved codes may vary by manufacturer

Common Symptoms

ABS warning light illuminated
Traction control warning light active
Reduced stability under braking
ABS may not engage properly
No drivability issues if ABS not needed

Most Common Causes

Faulty left rear ABS solenoid #1 medium

Common failure of the ABS solenoid electromagnet causing circuit malfunctions

Damaged or corroded wiring/connectors in ABS solenoid circuit medium

Open or shorted wiring can interrupt solenoid operation

Poor ground or power supply to ABS module medium

Electrical supply issues can mimic solenoid circuit faults

Scan tool communication anomaly or reserved code misinterpretation low

In many vehicles C0080 is an ISO/SAE reserved code with no specific meaning and may be a scanner artifact

Diagnostic Steps

Verify the code with an OEM-level or updated scan tool

Expected: Code appears consistently or only on generic scanner

Interpretation: Consistent presence suggests real fault; disappearance on OEM tool suggests scanner artifact
Inspect ABS wiring harness and left rear solenoid connectors

Expected: No corrosion, damage or loose pins

Interpretation: Damage supports electrical fault cause
Measure resistance of left rear ABS solenoid

Expected: Resistance within manufacturer specification

Interpretation: Out-of-spec indicates solenoid failure
Check power and ground at ABS module and solenoid circuit

Expected: Proper voltage and ground present

Interpretation: Lack of proper power/ground indicates supply issue
Clear code and test drive

Expected: Code returns or stays cleared

Interpretation: Persistent return suggests unresolved fault

Repair Solutions

Replace faulty left rear ABS solenoid #1 medium

Estimated Cost: $200 - $450

Typical repair when solenoid resistance out of spec

Repair or replace damaged wiring/connectors medium

Estimated Cost: $80 - $250

Cost depends on extent of damage

Update vehicle software or use OEM scanner to clear false C0080 code easy

Estimated Cost: $0 - $100

Useful when code is scanner artifact; may require dealer tool

Common Misdiagnoses

Avoid these common diagnostic mistakes:

Generic scanner misinterpreting reserved code as ABS solenoid fault

Frequently Asked Questions

What does the C0080 code mean?

Left Rear ABS Solenoid #1 Circuit Malfunction is the standard definition for C0080. This diagnostic code is triggered when the ECU detects a problem in the Sensors.

Can C0080 cause engine damage?

This is a medium priority issue. May disable ABS/traction control on left rear wheel; normal braking still functional but ABS performance compromised

What happens when the C0080 code is active?

The most typical signs are: ABS warning light illuminated, Traction control warning light active, Reduced stability under braking.

Potential causes for OBDII code C0080

This code is frequently triggered by: Faulty left rear ABS solenoid #1, Damaged or corroded wiring/connectors in ABS solenoid circuit, Poor ground or power supply to ABS module.

Repair cost breakdown for C0080

The cost varies significantly based on the root cause. For example, replacing a Update vehicle software or use OEM scanner to clear false C0080 code typically costs between $0 and $100, while fixing a Replace faulty left rear ABS solenoid #1 can range from $200 to $450.

Is C0080 a generic or manufacturer-specific code?

The C0080 code is a generic powertrain code, meaning it applies to almost all makes and models, such as Honda, Toyota, VW, Ford, and Chevy.
