Causes
- Internal ABS module hardware failure (PCB/component fault)
- Corrupted or failed ABS module software/firmware
- Intermittent or low supply voltage to ABS module (battery, ignition supply)
- Poor ground or corroded/loose module connector pins
- CAN/LIN bus communication errors or shorted data lines
- Water intrusion or physical damage to module housing
Symptoms
- ABS warning lamp and/or traction control light illuminated
- Loss or intermittent loss of ABS/traction control functions
- Brake pedal feel typically remains but ABS intervention (pulsing) not available
- Stored C1300 and possibly other ABS or CAN codes in scan tool
- Intermittent faults or module reboots; sometimes lights go out then reappear
- Possible no communication with ABS module on scan tool
What to check
- Use a capable scan tool to read freeze frame data and all stored ABS/CAN codes; note time/conditions of occurrence
- Check for other related codes (U-codes, C-codes) that indicate CAN or external sensor faults
- Visually inspect ABS module connector, harness, and module housing for corrosion, water ingress, or physical damage
- Verify battery voltage (key on engine off and engine running) and check related fuse(s) and relays
- Backprobe and measure module power feed and ground at the connector (with harness connected)
- Check chassis and engine ground points for tightness and corrosion
Signal parameters
- ABS module supply voltage (key ON): approximately 11–14.5 V expected
- Charging voltage with engine running: approximately 13.5–14.8 V
- Module ground: near 0 V (less than 0.5 V across ground reference)
- CAN bus idle voltages: CAN_H and CAN_L approximately 2.5 V each (differential ~0 V idle); active differential typically 1–2 V
- Wheel speed sensor signals (typical): passive VR sensors ~0.1–1.5 Vrms at low speed, increasing with speed; active Hall sensors 0–5 V square wave
- Module current draw: may vary by design; abnormal high or zero current can indicate internal fault
Diagnostic algorithm
- Connect a professional scan tool capable of ABS module diagnostics; record codes, freeze frames and current module software/part numbers
- Check battery state of charge and system voltage; ensure stable supply before continuing
- Visually inspect module and connector for moisture, corrosion, bent/broken pins and repair as needed
- Backprobe module power and ground pins with key ON; verify proper voltage and good ground under load
- Inspect fuses/relays related to ABS power; verify continuity to module power pin
- Scan bus for communication with ABS module; if module not present, trace CAN bus wiring, check termination resistances and other modules for bus faults
- If communication present, attempt a module self-test/diagnostic utility from the scan tool and document results
- Clear codes and road test to reproduce; if C1300 returns immediately or consistently, proceed to module bench or dealer-level diagnostics
- If power/ground/CAN are good and wiring intact, consider reprogramming/reflashing ABS module software per manufacturer procedure (follow safe procedures, stable battery voltage)
- If reflash fails or C1300 persists after reprogram, replace or repair ABS control module per manufacturer instructions and ensure proper module coding/configuration after installation
- After any repair, clear codes and verify proper operation including ABS self-tests and road test to confirm fault resolution
Likely causes
- Failed internal processor, memory or power regulator inside ABS module
- Corroded connector or pin causing intermittent internal reset
- Body/engine ground integrity issue causing module reset or damage
- CAN bus short or heavy noise preventing module boot or comms
- Previous repair or aftermarket device caused voltage spike or mis-configuration
Fault status
Status
C1300 — ABS Control Module Internal Fault: internal hardware or software error detected in ABS control module. Check module power/ground, CAN bus, connectors; reprogram or replace module if internal failure confirmed.
Repair difficulty: Hard
Diagnostic time: 1-3 hours
