Check Trans Indicator & Self Diagnosis

Warning to the driver

• "CHECK TRANS" is ON for 3 seconds at key switch ON
position.

• When trouble has occurred with electrical components,
"CHECK TRANS" lamp blinks (1.25 Hz) during driving to
warn the driver.

• The trouble is recorded by trouble code in TCM. When a
temporary trouble code has been canceled, the "CHECK
TRANS" lamp stops blinking. This blinking can be stopped
by setting the key off. The trouble code remains memorized
in TCM.

RTW77ASH000101 NOTE:

Key SW ON 1. If the "CHECK TRANS" lamp remains ON during key switch
ON ON position, the connection between the lamp and TCM
has shorted to ground.
OFF Verify the connection and wire between the TCM A20
3 Sec. terminal and the lamp which has shorted to ground.

(Lamp Check) 2. If the "CHECK TRANS" lamp remains OFF during key
switch ON position (Engine off), the connection between the
Illumination Pattern at Normal Condition lamp and TCM is open or the meter fuse (15A) has burnt
out.
Verify the connection and wire between the TCM A20
terminal and the lamp open circuit and meter fuse (15A).

Diagnosis with Tech 2

In this JR405E transmission, troubleshooting can be performed for electrical faults using the Tech 2 scan tool.
If the "CHECK TRANS" lamp blinks, or if an electrical fault in the transmission occurs, check trouble codes using
the Tech 2 scan tool.
Using the diagnostic procedures described in this manual, first repair the faulty positions indicated by the trouble
code in numerical order. Secondly, perform the troubleshooting procedures for the faults that are not indicated by a
trouble code. For correct troubleshooting, it is necessary to correct the faults in sequence, repair the faults with the
lower trouble codes first and then the higher codes.

If no codes are set:

• Refer to F1: Data Display and identify the electrical faults that are not indicated by a trouble code.
• Refer to "SYMPTOM DIAGNOSIS".

If codes are set:

1. Record all the trouble codes displayed by Tech 2. Check the ID code to identify if they are intermittent.
2. Clear the codes.
3. Drive the vehicle for a test to reproduce the faulty status.
4. Check trouble codes again using the Tech 2.
5. If no code is displays by test driving, the fault is intermittent. In this case, refer to "INTERMITTENT

DIAGNOSIS".
6. If a code is present, refer to DTC Chart for diagnosis.
7. Check the trouble codes again using the Tech 2.

The state of each circuit can be tested by using miscellaneous test menus. When DTC cannot be detected, a faulty
circuit can be diagnosed by testing each circuit using these menus.
Even if DTC has been detected, the circuit tests using these menus could help discriminate between a mechanical
fault and an electrical fault.

DIAGNOSIS (JR405E) 7A2-15

Intermittent Diagnosis

If the Tech 2 displays any codes as intermittent, or if after a test drive any code does not reappear, the problem is
most likely a faulty electrical connection or loose wiring.
Terminals should always be the prime suspect.
Intermittent faults rarely occur in sophisticated electronic components such as the TCM.
When an intermittent problem is encountered, check suspect circuits for:
• Poor terminal to wire connections.
• Terminals not fully seated in the connector body.
• Improperly formed or damaged terminals.
• Loose, dirty or damaged terminals.
Any time you have an intermittent fault in more than one circuit, check whether the circuits share a common ground
connection.
• Pinched or damaged wires.
• Electric interference.
Check for improperly installed electrical options, such as a light, radios, etc.

Use the F2: Snapshot mode of the Tech 2 to help isolate the cause of an intermittent fault. The snapshot mode will
record information before and after the problem occurs. Set the snapshot to "Trigger" on the suspected code or, if
you notice the reported symptom during a test drive, trigger the snapshot manually.
After the snapshot has been triggered, command the Tech 2 to play back the flow of data recorded from each of the
various sensors. Signs of an intermittent fault in a sensor circuit are a sudden, unexplainable jump in data values
out of the normal range.
