Precautions for On Board Diagnostic (OBD) System of A/T and Engine

The ECM has an on board diagnostic system. It will light up the malfunction indicator lamp (MIL) to warn the driver of a malfunction causing emission deterioration.

Scheme 267

1. Before connecting or disconnecting the TCM harness connector, turn ignition switch OFF and disconnect negative battery terminal. Failure to do so may damage the TCM. Because battery voltage is applied to TCM even if ignition switch is turned off.
2. When connecting or disconnecting pin connectors into or from TCM, take care not to damage pin terminals (bend or break). Make sure that there are not any bends or breaks on TCM pin terminal, when connecting pin connectors.
3. Before replacing TCM, perform TCM input/output signal inspection and make sure whether TCM functions properly or not. Refer to «INPUT/OUTPUT SIGNAL OF TCM»(ref-206576-S16887597082005112500000) .
4. After performing each TROUBLE DIAGNOSIS, perform DTC (Diagnostic Trouble Code) CONFIRMATION PROCEDURE. The DTC should not be displayed in the DTC CONFIRMATION PROCEDURE if the repair is completed.
5. Before proceeding with disassembly, thoroughly clean the outside of the transaxle. It is important to prevent the internal parts from becoming contaminated by dirt or other foreign matter.
6. Disassembly should be done in a clean work area.
7. Use lint-free cloth or towels for wiping parts clean. Common shop rags can leave fibers that could interfere with the operation of the transaxle.
8. Place disassembled parts in order for easier and proper assembly.
9. All parts should be carefully cleaned with a general purpose, non-flammable solvent before inspection or reassembly.
10. Gaskets, seals and O-rings should be replaced any time the transaxle is disassembled.
11. It is very important to perform functional tests whenever they are indicated.
12. The valve body contains precision parts and requires extreme care when parts are removed and serviced. Place disassembled valve body parts in order for easier and proper assembly. Care will also prevent springs and small parts from becoming scattered or lost.
13. Properly installed valves, sleeves, plugs, etc. will slide along bores in valve body under their own weight.
14. Before assembly, apply a coat of recommended ATF to all parts. Apply petroleum jelly to protect O-rings and seals, or hold bearings and washers in place during assembly. Do not use grease.
15. Extreme care should be taken to avoid damage to O-rings, seals and gaskets when assembling.
16. Replace ATF cooler if excessive foreign material is found in oil pan or clogging strainer. Refer to «ATF COOLER SERVICE»(ref-206576-S15530625732005112500000) .
17. After overhaul, refill the transaxle with new ATF.
18. When the A/T drain plug is removed, only some of the fluid is drained. Old A/T fluid will remain in torque converter and ATF cooling system. Always follow the procedures when changing A/T fluid. Refer to «SERVICING - A/T»(ref-142978) article .

OBD-II SELF-DIAGNOSIS

1. A/T self-diagnosis is performed by the TCM in combination with the ECM. The results can be read through the blinking pattern of the A/T check (position) indicator or the malfunction indicator lamp (MIL). Refer to «SELF-DIAGNOSTIC RESULT TEST MODE»(ref-206576-S42429752142005112500000) for the indicator used to display each self-diagnostic result.
2. The self-diagnostic results indicated by the MIL are automatically stored in both the ECM and TCM memories.
3. Always perform the procedure HOW TO ERASE DTC to complete the repair and avoid unnecessary blinking of the MIL.
4. The following self-diagnostic items can be detected using ECM self-diagnostic results mode* only when the A/T check (position) indicator lamp does not indicate any malfunctions. park/neutral position (PNP) switch

1. A/T 1st, 2nd, 3rd, or 4th gear function
2. A/T TCC S/V function (lock-up). *: For details of OBD-II, refer to «SELF-DIAGNOSTICS - ALTIMA»(ref-135505) article.

1. Certain systems and components, especially those related to OBD, may use a new style slide-locking type harness connector.

For description and how to disconnect, refer to HOW TO CHECK TERMINAL . .

Wiring Diagrams and Trouble Diagnosis

When you read wiring diagrams, refer to the following

1. «HOW TO READ WIRING DIAGRAMS»(ref-177331-S13148762022006041300000)
2. «POWER DISTRIBUTION»(ref-151282-S09691687642002121200000) When you perform trouble diagnosis, refer to the following
3. «HOW TO FOLLOW TEST GROUPS IN TROUBLE DIAGNOSE»(ref-177331-S36300051462006041300000)
4. «HOW TO PERFORM EFFICIENT DIAGNOSIS FOR AN ELECTRICAL INCIDENT»(ref-177331-S14523163872005052600000)

HOW TO READ DTC AND 1ST TRIP DTC

DTC and 1st trip DTC can be read by the following methods.

(With CONSULT-II or GST) CONSULT-II or GST (Generic Scan Tool) Examples: P0705, P0710, P0720, P0725, etc.

These DTCs are prescribed by SAE J2012.

(CONSULT-II also displays the malfunctioning component or system.)

1. 1st trip DTC No. is the same as DTC No.
2. Output of the diagnostic trouble code indicates that the indicated circuit has a malfunction. However, in case of the Mode II and GST they do not indicate whether the malfunction is still occurring or occurred in the past and returned to normal. CONSULT-II can identify them as shown below. Therefore, using CONSULT-II (if available) is recommended.

A sample of CONSULT-II display for DTC and 1st trip DTC is shown in the following page. DTC or 1st trip DTC of a malfunction is displayed in SELF DIAGNOSIS mode for ENGINE with CONSULT-II. Time data indicates how many times the vehicle was driven after the last detection of a DTC.

Scheme 268

If the DTC is being detected currently, the time data will be 0.

Scheme 269

If a 1st trip DTC is stored in the ECM, the time data will be 1t.

Scheme 270

HOW TO ERASE DTC

The diagnostic trouble code can be erased by CONSULT-II, GST or ECM DIAGNOSTIC TEST MODE as described following.

1. If the battery terminal is disconnected, the diagnostic trouble code will be lost within 24 hours.
2. When you erase the DTC, using CONSULT-II or GST is easier and quicker than switching the mode selector on the ECM.

The following emission-related diagnostic information is cleared from the ECM memory when erasing DTC related to OBD-II. For details, refer to SELF-DIAGNOSTICS - ALTIMA article.

1. Diagnostic trouble codes (DTC)
2. 1st trip diagnostic trouble codes (1st trip DTC)
