Honda Accord: Brake Pedal Position Switch Signal
Circuit Troubleshooting
1. Turn the ignition switch to ON (II).
2. Check the BRAKE SWITCH in the DATA LIST with the HDS.
Does it indicate OFF? YES
-Go to step 3.
NO
-lnspect the brake pedal position switch (see page 19-6).
3. Press the brake pedal, and check the BRAKE SWITCH in the DATA LIST with the HDS.
Does it change to ON? YES
-The brake pedal position switch signal circuit (BKSW line) is OK.
NO
-Go to step 1.
4. Turn the ignition switch to LOCK (0).
5. Jump the SCS line with the HDS.
6. Disconnect the brake pedal position switch 4P connector.
7. Disconnect ECM/PCM connector A (49P).
8. Check for continuity between ECM/PCM connector terminal A42 and body ground.
ECM/PCM CONNECTOR A (49P)
Terminal side of female terminals
Is there continuity? YES
-Repair short in the wire between the ECM/PCM (A42) and the brake pedal position switch. Replace the No. 10 HORN/STOP (20 A) fuse.B NO
-Go to step 9.
9. Connect brake pedal position switch 4P connector terminal No. 2 to body ground with a jumper wire.
