Honda HR-V: How to Information
HOW TO TROUBLESHOOT THE ELECTRIC PARKING BRAKE
System Indicator
The electrical parking brake system has two indicators:
- Electric parking brake system indicator (A)
- Electric parking brake indicator (B)
When the system is OK, each indicator comes on for about 2 seconds after
turning the vehicle to the ON mode,
then it goes off. If parking brake is applied, electric parking brake indicator
is still ON.
Electric Parking Brake System Indicator
- The electric parking brake system indicator comes on when the electric
parking brake function is lost.
- The electric parking brake system indicator blinks when the longitudinal
acceleration sensor neutral
position is not memorized after replacing the electric parking brake control
unit.
- The electric parking brake system indicator will also illuminate when
the HDS maintenance mode is
enabled.
Electric Parking Brake Indicator
- The electric parking brake indicator comes on when the electric parking
brake is applied.
- The electric parking brake indicator blinks when the electric parking
brake function is lost.
Diagnostic Trouble Code (DTC)
- The memory can hold 10 DTCs. However, when the same DTC is detected more
than once, the more
recent DTC is written over the earlier one. Therefore, when the same problem
is detected repeatedly, it is
memorized as a single DTC.
- The DTCs are indicated in ascending order, not in the order they
occurred.
- The DTCs are memorized in an EEPROM in the electric parking brake
control unit. Therefore, the
memorized DTCs cannot be erased by disconnecting the 12 volt battery. Do the
specified procedures to
clear the DTCs.
Self-Diagnosis
- Self-diagnosis can be classified into two categories:
- Initial diagnosis: Done right after turning the vehicle to the ON
mode and until the electric parking
brake system indicator goes off
- Regular diagnosis: Done right after the initial diagnosis until
turning the vehicle to the OFF
(LOCK) mode.
- When the system detects a problem, the electric parking brake control
unit shifts to fail-safe mode.
Electric Parking Brake actuator
- The electric parking brake actuator operates when the parking brake
applies or releases.
- The parking brake motor can be heard at the rear wheels when the parking
brake is applied or released,
this is normal.
Electric Parking Brake Forced Cancellation
- When the electric parking brake system has malfunction and parking brake
cannot be released, you can
release parking brake by doing forced cancellation procedure.
- Before doing electric parking brake forced cancellation, check for
electric parking brake system DTCs
with the HDS. If any DTCs are indicated, do the indicated DTC's
troubleshooting and repair the cause for
DTC first.
- If the electric parking brake switch fails, switch operation will be
disabled and the manual release is not
possible. However, depending on the malfunction, you may be able to release
the parking brake by
following procedures.
- Buckle the driver's seat belt.
- Turn the vehicle to the ON mode.
- Shift the transmission to D or R position/mode.
- Slowly depress the accelerator pedal.
Electric Parking Brake Maintenance Mode
- When replacing the rear brake pad, it is necessary to enter the
maintenance mode with the HDS.
- When the maintenance mode is not completed, the electric parking brake
system indicator comes on, and
the electric parking brake control unit sets code DTC C1100-53.
How to Troubleshoot DTCs
The troubleshooting procedures assume that the cause of the problem is still
present and the electric parking
brake system indicator is still on. Following a troubleshooting procedure for a
DTC that has been cleared but
does not reset can result in incorrect diagnosis.
1. Question the client about the conditions when the problem occurred, and
try to reproduce the same conditions
for troubleshooting. Find out when the electric parking brake system indicator
came on, such as during
activation, after activation, when the vehicle was traveling at a certain speed,
etc. If necessary, have the client
demonstrate the concern
2. When the electric parking brake system indicator does not come on during
the test-drive, but troubleshooting
is done based on the DTC, check for loose connectors, poor contact of the
terminals, etc. in the circuit indicated
by the DTC
3. After troubleshooting or the repairs are done, clear the DTCs, and
test-drive the vehicle under the same
conditions that originally set the DTCs. Make sure the electric parking brake
system indicator does not come
on.
Intermittent Failures
The term "intermittent failure" means a system may have had a failure, but it
checks OK now. If you cannot
reproduce the condition, check for loose connections and terminals. Also check
ground and power connections
related to the circuit that you are troubleshooting.
How to Use the HDS (Honda Diagnostic System)
NOTE: Make sure the 12 volt battery is in good condition and fully charged.
1. If the system indicator(s) stay on, connect the HDS to the data link
connector (DLC) (A) located under the
driver's side of the dashboard.
2. Turn the vehicle to the ON mode.
3. Make sure the HDS communicates with the vehicle. If it does not, go to the
DLC circuit troubleshooting.
4. Check the diagnostic trouble code (DTC) for all systems, troubleshoot the
powertrain DTCs first. Then refer
to the indicated DTC's troubleshooting, and do the appropriate troubleshooting
procedure.
NOTE:
How to Retrieve DTCs
1. With the vehicle in the OFF (LOCK) mode, connect the HDS to the data link
connector (DLC) under the
driver's side of the dashboard.
2. Turn the vehicle to the ON mode.
3. Make sure the HDS communicates with the vehicle. If it does not, go to the
DLC circuit troubleshooting.
4. Follow the prompts on the HDS to display the DTC(s) on the screen. After
determining the DTC, refer to the
DTC troubleshooting. Do the all systems DTC check, and troubleshoot any
powertrain DTCs first.
5. Turn the vehicle to the OFF (LOCK) mode.
How to Clear DTCs
1. With the vehicle in the OFF (LOCK) mode, connect the HDS to the data link
connector (DLC) under the
driver's side of the dashboard.
2. Turn the vehicle to the ON mode.
3. Make sure the HDS communicates with the vehicle. If it does not, go to the
DLC circuit troubleshooting.
4. Clear the DTC(s) by following the screen prompts on the HDS.
5. Turn the vehicle to the OFF (LOCK) mode.
