Llfl Position
As the engine turns, the ATF pump also starts to operate. Automatic transmission fluid (ATF) is drawn from (99) and
discharged into (1). Then, ATF pressure is controlled by the regulator valve and becomes line pressure (1). The torque
converter inlet pressure {92} enters (94) ol torque converter through the orilice and discharges into {9O).
The torque converter check valve prevents the torque converter pressure from rising.
Under this condition, the hydraulic pressure is not applied to the clutches.
NOTE: When used, "l€ft" or "right" indicates direction on the hydraulic circuit.

. Other automatic transmission problem (s)
Inspeclthe a utomatic transmission problem (s)accordingto the DTC (s)indicated with code m700.
(DTC)*: The DTCS in the parentheses are the codes the E indicator light indicates (blinks) when the service cnecK connec-tor is connected with the sDecialtool {SCS service connector).
NOTE: WhentheOBDll Scan Tool orHonda PGM Tester indicates the DTC(S) for the automatic transmission control sys-
tem, the scan tool or tester also indicates code P0700 simultaneously. Code P0700 means detection of some automatic
transmission problem on the PGM-Fl control system.
lf the self-diagnostic E indicator light does not blink. perform an inspection according to the table below.
NOTE:
. lf a custombr describes the symptom for code P1706 (6), P0725 (11) or P0715 (15), it will be necessary to recreate the
symptom by test-driving, then recheck the DTC,. Sometimes the E indicator light and the Malfunction Indicator Lamp (MlL) may come on simultaneously. lf so, check
the PGM-Fl system according to the DTC, then reset the memory by removing the BACK UP fuse in the under-dash
fuse/relay box for more than l0 seconds. Drive the vehicle for several minutes at a speed over 30 mph(50 km/h). then recheck the DTC.
. Disconnecting the BACK UP fuse also cancels the radio anti-theft code, preset stations and the clock setting. Get the
customer's code number, and make note of the radio presets before removing the fuse so you can reset them.
