TRANSAXLE APPLICATION
Note. For F4E/4EAT transaxle mechanical testing and repair, see OVERHAUL - F4E/4EAT - TYPE-F article.
DESCRIPTION & OPERATION
Input signals from sensors are sent to the PCM. The PCM can determine when the time and conditions are right for a shift or converter clutch application.
On F4E/4EAT - Type-F transaxle 4 electronic solenoids accomplish these functions; 3 On/Off solenoids for shifting and one On/Off solenoid for torque converter clutch control.
The PCM has built-in self-diagnosis, fail-safe code and warning code display for the main input sensors and solenoid valves.
Note. In addition to transmission fault codes, engine-related fault codes may be output during QUICK TEST procedure. These fault codes pertain to engine performance and must be repaired first as engine performance will greatly affect transmission operation. For information and testing procedures of engine-related fault codes and components, see appropriate TESTS W/CODES article in ENGINE PERFORMANCE section.
Engine Identification (ID) Codes
Engine ID codes are issued at beginning of KOER SELF-TEST. Codes are one-digit numbers represented by number of pulses displayed. (Схема №2) Engine ID code is equal to one-half the number of engine cylinders. For example, 2 pulses would indicate that engine is a 4 cylinder. ID code is used to verify proper PCM is installed and that SELF-TEST has been entered.
Description
Following procedures are functional tests of EEC-IV system. These following 4 basic test steps must be carefully followed in sequence, otherwise misdiagnosis or replacement of non-faulty components may result
- VISUAL CHECK
- EQUIPMENT HOOKUP.
- KOEO (Key On Engine Off) SELF-TEST.
- KOER (Key On Engine Running) SELF-TEST.
