Diagnosis Table - Honda TRX350TM Rancher Service Manual

2. If the code number could not be checked (the indicator did not blink), repeat steps 2 and 4.
3. If a failure is still not indicated (i. e., the ''N'' does not blink), the problem is as follows:
a) Electric shift does not operate (page 21-10) and/or
b) Faulty gear indicator (e. g., does not indicate the problem, keeps indicating the same gear position, indicates a different
gear position than what the transmission is in)
4. After performing the above troubleshooting steps and repairing the problem, delete the codes as follows:
a) Turn the ignition switch to ''OFF''.
b) Place the transmission in neutral.
c) Apply the parking brake so the vehicle does not move.
d) Push both the Upshift and Downshift switches to ''ON''.
e) While pushing them, turn the ignition switch to ''ON''.
Before the letter ''N'' appears on the shift position indicator (in about 2 seconds), release both the shift switches, then
push them again more than 3 seconds.
If the switches are not released and pushed within 2 seconds, the code number will not appear.
f) While the indicator is showing the problem code (i. e., blinking with the transmission in neutral), push both electric shift
switches to delete the problem code number.
g) Turn the ignition switch to ''OFF''.
