1. Check fluid level in reservoir tank. If low, add fluid. Fluid: ATF DEXRON HINT: Check that fluid level is within the HOT level on reservoir tank. If the fluid is cold, check that it is within the COLD level on the reservoir tank.
2. Bleed cooling system

SST Terminal Identification:

a. Using SST 09843-18020, connect terminals Op1 and E1 of the DLC. HINT: When terminals OP1 and E1 are connected, the circuit of the ECT sensor is grounded. fixing the cooling fan speed at approx. 1,100 rpm. (Fail-safe operation occurs.)
b. Start the engine without depressing the accelerator pedal.
c. Leave the engine running for several seconds.
