P061E

What it means

P061E is the generic SAE J2012 code for Internal Control Module Brake Signal Performance. The module that monitors the brake signal (usually the engine control module or powertrain control module) has found that the brake signal it receives, or its own internal processing of that signal, is not plausible or does not agree with other inputs. The exact signal path and the way the check is run depend on the make and model.

Symptoms

• Engine warning light on
• Cruise control or adaptive cruise not working
• Brake lights staying on, or not coming on, when the pedal is pressed
• Reduced engine power or limp mode in some vehicles
• Idle speed or throttle response feels different when braking or coming to a stop
• Other warning lights, such as stability control, may appear on some models

Possible causes

• Faulty or misadjusted brake pedal switch (brake light switch), or a switch with two circuits that disagreelikely
• Wiring faults in the brake switch circuit, such as chafing, corrosion, a short or an open circuitlikely
• Poor connections or water ingress at the switch connector or control module connectorpossible
• Low or unstable system voltage, from a weak battery or charging fault, upsetting the signalpossible
• Faulty brake pressure or pedal position sensor on models that use one as a plausibility checkpossible
• Internal fault in the control module, or outdated software where the manufacturer has issued a fixrare

How to diagnose

1. Read all stored and pending codes and the freeze frame data, and note any other brake, stability control or network codes
2. Check the brake lights operate correctly with the pedal pressed and released, and that they go out fully when released
3. Inspect the brake pedal switch for correct adjustment, damage, and any mechanical interference at the pedal
4. Inspect the switch wiring and connectors for damage, corrosion, moisture and loose pins
5. View live data for the brake switch status and watch it change cleanly as the pedal is pressed and released, comparing both circuits if the vehicle has two
6. Test battery condition and charging voltage, and rectify any low-voltage problem before going further
7. Check the switch circuit supply, signal and earth with a multimeter against the manufacturer's wiring diagram
8. Check for applicable software updates or technical bulletins for the model and engine before considering module replacement

How to fix

• Replace the brake pedal switch and set it up correctly if it is faulty or out of adjustment
• Repair or replace damaged wiring and connectors in the brake signal circuit
• Clean or repair corroded connections and seal against water ingress
• Repair the battery or charging system if low voltage is confirmed
• Replace a faulty brake pressure or pedal position sensor if testing shows it is at fault
• Update the control module software where an outdated calibration is a known cause, or replace the module if it is proven faulty
