   P1E26-00 Brake Pedal Stroke Sensor/Brake Pedal Stroke Redundant Sensor Incorrect Correlation

   Is DTC P1E26-00 indicated?

   YES 

   The failure is duplicated. Go to step 2.

   NO 

   Intermittent failure, the system is OK at this time. Refer to intermittent failures troubleshooting . If the freeze data/on-board snapshot of this DTC is recorded, try to reproduce the failure under the same conditions with the freeze data/on-board snapshot.

2. Shorted wire check (BPS line to BPSR line) 1

   -1. Turn the vehicle to the OFF (LOCK) mode with driver's door open.

   -2. Wait for 3 minutes.

   NOTE:  Do not close the driver's door.

   -3. Disconnect the following connector.

   Electric servo brake control unit 22P connector

   -4. Measure the resistance between test points 1 and 2.

   Test condition	Vehicle OFF (LOCK) mode
   	Electric servo brake control unit 22P connector: disconnected
   Test point 1	Electric servo brake control unit 22P connector No. 8
   Test point 2	Electric servo brake control unit 22P connector No. 11

   Is there 1 MΩ or more?

   YES 

   Check for loose terminals and poor connections in the electric servo brake control unit 22P connector. Check for any authorized service information related to the DTCs or symptoms you are troubleshooting. If they are OK, replace the electric servo brake control unit/pedal feel simulator .

   NO 

   Go to step 3.

3. Shorted wire check (BPS line to BPSR line) 2

   -1. Disconnect the following connector.

   Brake pedal stroke sensor 4P connector

   -2. Measure the resistance between test points 1 and 2.

   Test condition	Vehicle OFF (LOCK) mode
   	Electric servo brake control unit 22P connector: disconnected
   	Brake pedal stroke sensor 4P connector: disconnect
   Test point 1	Electric servo brake control unit 22P connector No. 8
   Test point 2	Electric servo brake control unit 22P connector No. 11

   Is there 1 MΩ or more?

   YES 

   Replace the brake pedal .

   NO 

   Repair a short in the wire between the electric servo brake control unit and the brake pedal stroke sensor.
