DIAGNOSTIC TROUBLE CODE PROCEDURES
23Ac-255
.
CIRCUIT OPERATION
If a fail-safe is triggered while driving forward, the
PCM flashes the "N" range light once per second
(triggered fail-safe). The PCM does this by switching
battery positive voltage to terminal 75.
.
DTC SET CONDITIONS
If the PCM detects a fail-safe condition, it will attempt
to illuminate the "N" range light. The PCM sends a 12
volts pulse for 60
− 180 ms. If it does not detect a
voltage drop during the pulse, it waits about 60 sec-
onds and pulses 12 volts again for 60
− 180 ms. If
the PCM does no detect the voltage drop before the
ignition switch is turned the "LOCK" (OFF), the PCM
will consider it as an short circuit of the "N" range
light circuit and DTC 56 is set.
.
TROUBLESHOOTING HINTS (The most likely
causes for this code to be set are:)
• Defective "N" range light bulb
• Damaged harness, connector
• Malfunction of the PCM
