Can a bad battery cause electrical codes?

Yes, a weak or failing battery can cause voltage drops that affect various modules and sensors, potentially triggering multiple codes. Always check battery health and charging system first.

How much do electrical repairs cost?

Electrical repairs range from $75 for a simple connector fix to $400+ for wiring harness repairs or module replacements. ECM/PCM replacement can cost $500-$1,500 including programming.

C0201

ABS Motor Relay Circuit Short to Ground

Severeelectrical

Overview

The C0201 code indicates that the chassis control module has detected a abs motor relay circuit short to ground condition. This relates to the vehicle's chassis systems including ABS, stability control, steering, and suspension. A fault in these systems can affect vehicle safety and handling, and should be diagnosed and repaired promptly.

Symptoms

Check Engine Light (MIL) illuminated
Multiple warning lights on dashboard
Battery draining overnight
Electrical accessories malfunctioning

Common Causes

Internal module software error
Faulty engine control module (ECM/PCM)
Failed relay or fuse
Corroded or damaged wiring connectors

Diagnosis Steps

1Connect an OBD-II scanner and read all stored trouble codes and freeze frame data
2Check battery voltage and charging system output with a multimeter
3Inspect wiring and connectors related to the trouble code
4Test circuit voltage, ground, and resistance with a multimeter
5Check related fuses and relays
