DIAGNOSIS SYSTEM
1. CHECK DLC3
(a) Check the DLC3 (See page
).
2. INSPECT BATTERY VOLTAGE
(a) Measure the battery voltage.
Standard Voltage:
11 to 14 V
If the voltage is below 11 V, recharge or replace the battery.

Knock Sensor 1 Circuit Low Input (Bank 1 or Single Sensor) (P0327,P0328)
DESCRIPTION
Flat-type knock sensors (non-resonant type) have structures that can detect vibrations
between approximately 5 and 15 kHz.
Knock sensors are fitted onto the engine block to detect engine knocking.
The knock sensor contains a piezoelectric elem ...
Low Battery Positive Voltage or Abnormally High Battery Positive Voltage (C1241/41)
DESCRIPTION
If a malfunction is detected in the power supply circuit, the skid control ECU
(housed in the actuator assembly) stores this DTC and the fail-safe function prohibits
ABS operation.
This DTC is stored when the IG1 terminal voltage deviates fro ...
