PROCEDURE
1. INSPECT THERMISTOR ASSEMBLY
(a) Check the resistance.
| (1) Measure the resistance according to the value(s) in the table below.
Standard Resistance: |
Tester Connection | Condition |
Specified Condition | |
A3-1 - A3-2 | 10°C (50°F) |
3.00 to 3.73 kΩ | | A3-1 - A3-2 |
15°C (59°F) | 2.45 to 2.88 kΩ | |
A3-1 - A3-2 | 20°C (68°F) |
1.95 to 2.30 kΩ | | A3-1 - A3-2 |
25°C (77°F) | 1.60 to 1.80 kΩ | |
A3-1 - A3-2 | 30°C (86°F) |
1.28 to 1.47 kΩ | | A3-1 - A3-2 |
35°C (95°F) | 1.00 to 1.22 kΩ | |
A3-1 - A3-2 | 40°C (104°F) |
0.80 to 1.00 kΩ | | A3-1 - A3-2 |
45°C (113°F) | 0.65 to 0.85 kΩ | |
A3-1 - A3-2 | 50°C (122°F) |
0.50 to 0.70 kΩ | | A3-1 - A3-2 |
55°C (131°F) | 0.44 to 0.60 kΩ | |
A3-1 - A3-2 | 60°C (140°F) |
0.36 to 0.50 kΩ |
NOTICE:
- Hold the sensor only by its connector. Touching the sensing portion may change the resistance value.
- When measuring, the sensor temperature must be the same as the ambient temperature.
HINT: As the temperature increases, the resistance decreases (see the graph).
If the result is not as specified, replace the thermistor assembly. |

DESCRIPTION The ECM calculates the necessary cooling amount based on the engine coolant temperature, engine speed and vehicle speed, and controls the inverter water pump with motor assembly accordingly. The inverter water pump with motor assembly controls the speed of the inverter water pump with mo
DESCRIPTION
The ABS motor relay is built into the brake actuator assembly.
When the skid control ECU (brake actuator assembly) operates
ABS, TRAC, VSC, brake hold or brake assist, the ABS motor relay turns ON and drives
the motor pump built into the brake actuator assembly.
DTC No.
