Section 3 (Automatic Transmission Diagnosis - BAXA, B6VA & MDWA): Description

WARNING: This page is about a different car, the 1998 Honda Odyssey, 1998 Honda Accord, and 1998 Acura 2.3CL. However, it is still accessible from the selected car via links, so may be relevant.

CAUTION: Vehicle is equipped with a Supplemental Restraint System (SRS). When servicing vehicle, use care to avoid accidental air bag deployment. All SRS electrical connections and wiring harnesses are covered with Yellow insulation. SRS-related components are located in steering column, center console, instrument panel and lower panel on instrument panel. DO NOT use electrical test equipment on these circuits. It may be necessary to deactivate SRS before servicing components. See AIR BAG DEACTIVATION PROCEDURES article in GENERAL INFORMATION.

NOTE: Obtain radio anti-theft code from vehicle owner before disconnecting negative battery cable. Radio anti-theft code must be re-entered into radio once negative battery cable is reconnected. To re-enter radio anti-theft code, turn ignition and radio on. When CODE is displayed on radio, re-enter radio anti-theft code by using radio station preset buttons.

Automatic transaxle is electronically controlled. Transaxle shifting and torque converter lock-up are controlled by Powertrain Control Module (PCM). PCM is located below instrument panel under front lower panel in center console area on Accord and under right side of instrument panel on all others. PCM receives information from various input devices and uses this information to control shift, A/T clutch pressure control solenoid valves and lock-up control solenoid valves.

The PCM contains a grade logic control system which controls transaxle shifting while vehicle is ascending or descending a slope, or reducing vehicle speed. Transaxle is equipped with shift and key interlock systems. Shift interlock system prevents shift lever from being moved from Park unless brake pedal is depressed and accelerator pedal is in idle position. In case of a malfunction, shift lever can be released by placing ignition key in key release slot near shift lever. Key interlock system prevents ignition key from being removed from ignition lock assembly unless shift lever is in Park. For diagnosis of interlock systems, see appropriate SHIFT INTERLOCK SYSTEMS article.

The A/T gear position indicator on instrument panel contains lights to indicate position of A/T gear position switch on shift lever.
