| Title: BRAKE CONTROL / DYNAMIC CONTROL SYSTEMS: VEHICLE STABILITY CONTROL SYSTEM (w/ Electric Parking Brake System): C1417; High Power Supply Voltage Malfunction; 2018 - 2020 MY Camry [06/2017 - 10/2020] | ||
|
DTC |
C1417 |
High Power Supply Voltage Malfunction |
DESCRIPTION
If a malfunction is detected in the power supply circuit, the skid control ECU (brake actuator assembly) stores this DTC and the fail-safe function prohibits ABS operation.
This DTC is stored when the +BS terminal voltage deviates due to a malfunction in a power supply or charging system circuit such as the battery or alternator circuit, etc.

2. |
CHECK HARNESS AND CONNECTOR (POWER SOURCE TERMINAL) |
|
(a) Make sure that there is no looseness at the locking part and the connecting part of the connector. OK: The connector is securely connected. |
|
(b) Disconnect the A34 skid control ECU (brake actuator assembly) connector.
(c) Check both the connector case and the terminals for deformation and corrosion.
OK:
No deformation or corrosion.
(d) Measure the voltage according to the value(s) in the table below.
Standard Voltage:
|
Tester Connection |
Condition |
Specified Condition |
|---|---|---|
|
A34-30 (+BS) - Body ground |
Always |
11 to 14 V |
|
A34-30 (+BS) - A34-46 (GND1) |
Always |
11 to 14 V |
|
A34-36 (IG1) - Body ground |
Engine switch on (IG) |
11 to 14 V |
|
A34-36 (IG1) - A34-46 (GND1) |
Engine switch on (IG) |
11 to 14 V |
| NG |
|
REPAIR OR REPLACE HARNESS OR CONNECTOR (POWER SOURCE CIRCUIT) |
|
|
3. |
RECONFIRM DTC |
(a) Turn the engine switch off.
(b) Reconnect the A34 skid control ECU (brake actuator assembly) connector.
(c) Clear the DTCs.
Chassis > ABS/VSC/TRAC/EPB > Clear DTCs
(d) Turn the engine switch off.
(e) Start the engine.
(f) Perform a road test.
(g) Check if the same DTC is output.
