ON-VEHICLE INSPECTION
PROCEDURE
1. CHECK RADIATOR CAP SUB-ASSEMBLY
(a) Measure the valve opening pressure.
(1) If there are water stains or foreign matter on rubber packings 1, 2 or 3, clean the part(s) with water and finger scouring.
(2) Check that rubber packings 1, 2 and 3 are not deformed, cracked or swollen.
(3) Check that 3 and 4 are not stuck together.
(4) Apply engine coolant to rubber packings 2 and 3 before using the radiator cap tester.
(5) When using the cap tester, tilt it to 30° or more above level. |
|
(6) Pump the cap tester several times, and check the maximum pressure*.
Pump speed:
1 pump per second
*: Even if the cap cannot maintain the maximum pressure, it is not a defect.
Judgment Criterion:
Item |
Specified Condition |
---|---|
Standard value (for brand-new cap) |
94 to 122 kPa (1.0 to 1.2 kgf/cm2, 13.6 to 17 psi) |
Minimum standard value (for used cap) |
79 kPa (0.8 kgf/cm2, 11.4 psi) |
If the measured maximum pressure is less than the minimum standard value, replace the radiator cap sub-assembly.

ECU Power Source Circuit
DESCRIPTION
When the ignition switch is turned to ON, voltage from the ECM's MREL terminal
is applied to the EFI MAIN relay. This causes the contacts of the EFI MAIN relay
to close, which supplies power to terminal +B of the TCM.
