DRIVETRAIN SYSTEM
INDICATOR BLINK PATTERN
• The number of indicator blinks is the equivalent the main code of the DTC (the sub code cannot be
displayed by the indicator blinking).
• The indicator has two types of blinks, a long blink and short blink. The long blink lasts for 1.3 sec-
onds, the short blink lasts for 0.5 seconds. One long blink is the equivalent of ten short blinks. For
example, when one long blink is followed by five short blinks, the DTC is 15 (one long blink = 10
blinks, plus five short blinks).

• When the PCM stores more than one DTC, the indicator displays in the order from the lowest number
to highest number.
CURRENT DTC/FREEZE DTC
The DTC is indicated in two ways according to the
failure status.
• If the PCM detects the problem at present, the
gear position indicator and 4WD indicator will
blink at all time. It is possible to readout the indi-
cator blink pattern as the current DTC.
• If the PCM does not detect any problem at
present but has a problem stored in its memory,
the indicator will not blink. If it is necessary to
retrieve the past problem, readout the freeze DTC
by following the DTC readout procedure.
HDS POCKET TESTER INFORMATION
Refer to the "How to connect the HDS Pocket Tester"
and "ECM Reset" information in "Fuel system (PGM-
Fl)" (page 6-13).
DTC READOUT
Reading DTC with the indicator
NOTE:
• If the MIL blinks, refer to the "PGM-FI Trouble-
shooting Information" and troubleshoot the
PGM-FI system first. Then recheck the Drivetrain
system after clearing the PGM-FI DTC.
• After performing diagnostic troubleshooting,
erase the problem code(s) (page 14-22) and test-
drive the vehicle to be sure that the problem(s)
have been removed.
Turn the ignition switch on and connect the HDS
Pocket Tester to the DLC (page 6-14).
Read the DTC, freeze data and follow the trouble-
shooting index (page 14-24).
To read the DTC without the HDS pocket tester, refer
to the following procedure.
