Step 22 (Check of serviceability of giving of food on the relay of 1 fan)


Include ignition (the engine do not start) and measure tension between the plug No. 21 (+) of the F28 socket and the mass of the chassis. If the result of measurement makes more than 10 V, pass to the Step 26, otherwise execute check of the Step 25.

Step 23 (Check of a condition of the 30-ampere safety lock)

Take the corresponding 30-ampere safety lock from the assembly block of the relay of system K/V. Replace the fused safety lock. If safety locks as it should be, pass to the Step 24.

Step 24 (Check of serviceability of giving of food to plugs of the 30-ampere safety lock)

Measure tension between the plug No. 3 (+) of the F27 socket in the assembly block of the relay of system To/in and the mass of the chassis. If the result of measurement makes more than 10 V, check a chain site between a safety lock and the relay of 1 auxiliary fan for break, otherwise check for break a chain site between a safety lock and the socket of the main assembly block.

Step 25 (Check of a safety lock 18)

Switch off ignition, take a safety lock No. 18 from the landing nest and visually estimate its condition. Replace the fused safety lock. If a safety lock as it should be, check for break a chain site between the relay of 1 auxiliary fan and the switch of ignition.

Step 26 (Check of a condition of the relay of 1 auxiliary fan)

Switch off ignition and measure resistance between plugs No. No. 23 and 24 of the relay. If the result of measurement makes more than 1 megohm, pass to the Step 27, otherwise replace the relay 1.

Step 27 (Check of a condition of the relay of 1 auxiliary fan)

Connect the battery to plugs No. No. 21 and 22 of the relay, then repeat check of the Step 26. If the result of measurement makes less than 1 Ohm, pass to the Step 28, otherwise replace the relay 1.

Step 28 (Check of a condition of an electrical wiring between plugs of the relay of 1 auxiliary fan and the socket of a driving electric motor)

2. Measure resistance between the plug No. 22 of the F28 socket and the plug No. 28 of the B137 socket. If the result of measurement makes less than 1 Ohm, pass to the Step 30, otherwise eliminate break of an electrical wiring.

Step 30 (Quality check of contact connections)


Visually estimate a condition of plugs of contact sockets of a plait of the electrical wiring connecting the auxiliary fan to ECM. Make necessary corrections. If an electrical wiring as it should be, ask for the help experts firm HUNDRED Subarus.
