honda accord 1994 special edition problem
 

Need to know if there is anyone that can help with replacing and diagnosing the tcutcm in hayward.

What are your symptoms? No start, no crank, poor performance? details needed.

good luck

The d4 light blinks really fast and the gear won't shift from the park position. Tried replacing all the solenoids abd main relay and added a used transmission because old one got bad. Been having this problem for over a year now. Need someone that can tell if the tcu or tcm ecu is bad. And if it is there someone that can fix it. Iam in Hayward , CA.

First get the TCU code that is present (D4 light blinking means a code is set).

Short service check connector, turn keyswitch to On, and watch the D4 blinks. One long blink, followed by code where Long Flash (F) =10 and short flash (f) =1. So flashes F-ffff = 14, a long pause will separate multiple codes or repeat of same code.

Post code for guidance.

Failure of gear shift to move can be simple; brake light not working or mis-adjusted lock-out solenoid, or faultly keyswitch. What happens when you bypass the lockout w/ a key in the bypass opening?

good luck
