SERVICE TIP:
Troubleshooting an ABS/TCS DTC 68 (brake pedal position switch) in a 2003-05 Accord V6? Here's something you want to keep in mind: the brake pedal position switch test on page 22-173 of the 2003-2005 Accord S/M may not find the cause. That's because the continuity checks you do at the 4P connector don't put a load on the brake pedal position switch.



A better way to check terminals No. 1 and No. 2 of the 4P connector is to press the brake pedal, and watch the brake lights. If the brake lights come on, the terminals are OK. If the brake lights don't come on, make sure there are 12 volts at terminal No. 1. If you read 12 volts, then replace the brake pedal position switch. If you don't read 12 volts, then troubleshoot the circuit.

To check terminals No. 3 and No. 4, test-drive the vehicle above 30 mph, and set the cruise control. If the cruise control sets, the switch is OK. If it doesn't set, then replace the brake pedal position switch.
