DTC 68-22: Brake Pedal Position Switch Stuck ON

WARNING: This page is about a different car, the 2011 Honda Fit, 2010 Honda Fit, and 2009 Honda Fit. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Before you troubleshoot, record all freeze data and any on-board snapshot, and review the general troubleshooting information. (See General Troubleshooting Information ).

Start the engine.
Check the BRAKE PRESS in the VSA DATA LIST with the HDS. Do not press the brake pedal.
Is there 10 MPa or more?

YES - Check the brake pedal height (see BRAKE PEDAL AND BRAKE PEDAL POSITION SWITCH ADJUSTMENT ). If the brake pedal height is OK, go to step 10.

NO - Go to step 3.
Check the BRAKE SWITCH in the VSA DATA LIST with the HDS while moving the brake pedal.
Does it indicate ON when the pedal is pressed, and OFF when the pedal is released?

YES - Intermittent failure, the system is OK at this time. Refer to intermittent failures troubleshooting (see Intermittent Failures ).

NO - Go to step 4.
Check the BRAKE SWITCH in the VSA DATA LIST with the HDS, and disconnect the brake pedal position switch 4P connector. (See BRAKE PEDAL AND BRAKE PEDAL POSITION SWITCH ADJUSTMENT ).
Does the indicator change from ON to OFF?

YES - Inspect the brake pedal position switch and adjustment. If the brake pedal position switch and adjustment are OK, replace the brake pedal position switch. (See BRAKE PEDAL AND BRAKE PEDAL POSITION SWITCH ADJUSTMENT ).

NO - Go to step 5.
Turn the ignition switch to LOCK (0).
Short the SCS line with the HDS.
Disconnect ECM/PCM connector A (49P). See ECM/PCM REPLACEMENT .
Turn the ignition switch to ON (II).
Measure the voltage between brake pedal position switch 4P connector terminal No. 2 and body ground.

Is there 0.1 V or more?

YES - Repair short to power in the wire between the ECM/PCM and the brake pedal position switch.

NO - Update the ECM/PCM if it does not have the latest software (see ECM/PCM UPDATE ), or substitute a known-good ECM/PCM (see SUBSTITUTING THE ECM/PCM ), then go to step 1 and recheck. If the ECM/PCM was updated and DTCs are not indicated, troubleshooting is complete. If the ECM/PCM was substituted and DTCs are not indicated, replace the original ECM/PCM (see ECM/PCM REPLACEMENT ).
Update the VSA modulator-control unit if it does not have the latest software (see VSA MODULATOR-CONTROL UNIT UPDATE ).
Turn the ignition switch to LOCK (0), then turn it to ON (II) again.
Check for DTCs with the HDS.
Is DTC 68-22 indicated?

YES - Check for loose terminals in the VSA modulator-control unit 36P connector. If the symptom/indication is still present, replace the VSA modulator-control unit (see VSA MODULATOR-CONTROL UNIT REMOVAL AND INSTALLATION ).

NO - If the VSA modulator-control unit was updated, troubleshooting is complete. If any other DTCs are indicated, go to the indicated DTCs troubleshooting.
