C1355 Toyota Code - Increasing Pressure Solenoid Malfunction Rear Left
Quick Answer
The C1355 diagnostic trouble code (DTC) indicates a malfunction in the increasing pressure solenoid located in the rear left brake system of a Toyota vehicle. Common causes include Electrical Issues: Damaged wiring, corroded connectors, or short circuits can disrupt the solenoid's operation, triggering the C1355 code, Faulty Solenoid: The increasing pressure solenoid itself may be defective due to wear and tear, leading to malfunction, ABS Control Module Failure: A malfunction in the ABS control module can prevent proper communication and operation of the solenoid. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code C1355 Toyota Description
The C1355 diagnostic trouble code (DTC) indicates a malfunction in the increasing pressure solenoid located in the rear left brake system of a Toyota vehicle. This solenoid is a critical component of the vehicle's anti-lock braking system (ABS) and traction control system (TCS). It is responsible for modulating hydraulic pressure to the rear left brake caliper, ensuring optimal braking performance and stability during various driving conditions.
Common Causes of C1355 Toyota
- Electrical Issues: Damaged wiring, corroded connectors, or short circuits can disrupt the solenoid's operation, triggering the C1355 code.
- Faulty Solenoid: The increasing pressure solenoid itself may be defective due to wear and tear, leading to malfunction.
- ABS Control Module Failure: A malfunction in the ABS control module can prevent proper communication and operation of the solenoid.
- Fluid Contamination: Contaminated brake fluid can affect the solenoid's performance and lead to hydraulic issues within the braking system.
- Mechanical Blockages: Debris or blockages in the brake lines or solenoid can impede fluid flow, causing the solenoid to malfunction.
Symptoms of C1355 Toyota
- Illuminated Warning Lights: The ABS or brake warning light may be illuminated on the dashboard, indicating a fault in the braking system.
- Reduced Braking Performance: Drivers may notice a decrease in braking efficiency, requiring more force on the brake pedal to achieve the desired stopping power.
- Uneven Brake Wear: The rear left brake may wear out faster than the other brakes, leading to premature replacement and potential safety hazards.
- Increased Stopping Distance: The vehicle may take longer to stop, especially under hard braking conditions, which can be dangerous.
- Unusual Noises: There may be grinding or whining noises coming from the rear left brake area, indicating potential mechanical issues.
How to Fix C1355 Toyota
- Diagnostic Scan: Use an OBD-II scanner to confirm the C1355 code and check for any additional codes that may provide further insight into the issue.
- Visual Inspection: Inspect the wiring and connectors leading to the increasing pressure solenoid for signs of damage, corrosion, or loose connections.
- Test the Solenoid: Perform a resistance test on the solenoid to determine if it is functioning within the manufacturer's specifications. Replace if faulty.
- Check the ABS Control Module: If the solenoid is functioning correctly, test the ABS control module for faults and replace if necessary.
- Brake Fluid Flush: If fluid contamination is suspected, perform a brake fluid flush to ensure clean fluid circulates through the system, and check for any blockages.
Cost to Fix C1355 Toyota
The typical repair costs for addressing a C1355 code can vary widely based on the specific diagnosis and repairs needed. On average, the cost may range from $200 to $800. This estimate includes parts, such as a new solenoid or ABS control module, and labor costs. Labor rates at auto repair shops can differ based on location, vehicle make and model, and engine type. Most shops charge between $80 and $150 per hour; however, rates in metropolitan areas or at dealerships may be higher, while independent shops often charge less. It is advisable to check local rates for a more precise estimate and to obtain quotes from multiple repair facilities to ensure competitive pricing.

Frequently Asked Questions about C1355 Toyota Code
What does the OBDII code C1355 mean on a Toyota?
C1355 indicates an "Increasing Pressure Solenoid Malfunction" in the rear left wheel, which is part of the vehicle's ABS or traction control system.
What are the common symptoms of code C1355?
Common symptoms include the ABS or traction control warning light illuminating, reduced braking performance, and potential instability during braking.
What causes the C1355 code to appear?
The code can be triggered by a faulty rear left pressure solenoid, damaged wiring or connectors, issues with the ABS control module, or contamination in the brake fluid.
Can I drive with the C1355 code active?
Driving with this code is not recommended, as it may compromise the ABS or traction control system, increasing the risk of losing control during braking.
How do I diagnose the C1355 code?
Diagnosis involves using an OBDII scanner to confirm the code, visually inspecting the wiring and connectors, and testing the rear left solenoid for proper operation.
What tools are needed to fix code C1355?
You may need an OBDII scanner, a multimeter for electrical testing, basic hand tools, and possibly a brake fluid bleeder if fluid replacement is necessary.
How much does it cost to repair the C1355 code?
Repair costs vary depending on the issue, ranging from $100 for minor fixes like wiring repairs to $500 or more if the ABS module or solenoid must be replaced.
Can a dirty brake fluid cause the C1355 code?
Yes, contaminated or old brake fluid can affect solenoid function, potentially triggering the C1355 code.
How can I prevent the C1355 code from occurring?
Regular maintenance, including brake fluid replacement and inspecting the ABS components, can help prevent this issue.
Will clearing the C1355 code with a scanner fix the problem?
Clearing the code will only reset the warning temporarily; the underlying issue must be fixed to prevent the code from reappearing.
