TROUBLESHOOTING (A/T)
(F4A42 MODEL)
Scheme 36
DIAGNOSIS FUNCTION
- Connect the Hi Scan Pro to the data link connector for diagnosis.
- Read the output diagnostic trouble codes. Then follow the remedy procedures according to the "DIAGNOSTIC TROUBLE CODE DESCRIPTION" on the following pages. NOTE: A maximum of 8 diagnostic trouble codes (in the sequence of occurrence) can be stored in the Random Access Memory (RAM) incorporated within the control module. The same diagnostic trouble code can be stored one time only. If the number of stored diagnostic trouble codes or diagnostic trouble patterns exceeds 8, already stored diagnostic trouble codes will be erased in sequence, beginning with the oldest. Do not disconnect the battery until all diagnostic trouble codes or diagnostic trouble patterns have been read out, because all stored diagnostic trouble codes or diagnostic trouble patterns will be cancelled when the battery is disconnected.
- If the fail-safe system is activated and the transaxle is locked in third gear, the diagnostic trouble code in the fail-safe code description will be stored in the RAM. Three of these diagnostic trouble codes can be stored.
- The cancellation will occur if, with the transaxle locked in third gear, the ignition key is turned to the OFF position, but the diagnostic trouble code is stored in the RAM.
- Memorization Up to 8 diagnosis items and 3 fail-safe items can be memorized. If the memory capacity is exceeded, diagnosis and fail-safe items in the memory are overwritten, starting with the oldest. No code can be memorized more than once.
- Diagnosis Code Deletion Automatic Deletion All diagnosis codes are deleted from memory the 200th time the ATF temperature reaches 50°C after memorization of the most recent diagnosis code Forced Deletion Memorized diagnosis codes can be deleted using the scan-tool, provided the following conditions are satisfied: The ignition switch is ON. There is no detection pulse from the crank angle sensor. There is no detection pulse from the output shaft speed sensor. There is no detection pulse from the vehicle speed sensor. The fail-safe function is not operational.

HYDRAULIC PRESSURE TEST
- Warm up the engine until the automatic transaxle fluid temperature is 80-100°C.
- Jack up the vehicle so that the wheels are free to turn.
- Connect the special tools oil pressure gauge to each pressure discharge port.
- Measure the hydraulic pressure at each port under the conditions given in the standard hydraulic pressure table, and check that the measured values are within the standard value ranges.
- If a value is outside the standard range, correct the problem while referring to «HYDRAULIC PRESSURE TEST DIAGNOSIS TABLE»(ref-172511-S29998402172005022800000) .
