1 Nissan Ireland PO Box 910 Naas Road Dublin 12 Technical Bulletin REFERENCE: MODEL: After-Sales Service Technical Support Communication Letter T31 X-TRAIL SUBJECT: TB T31 Cannot erase DTC P1435 and cannot clear MIL. Background: Dealer cannot erase DTC P1435 and cannot clear MIL. P1435 is caused by Regeneration Failure Counter. After normal regeneration during driving, Regeneration Failure Counter is reset to 0. After Service Regeneration, Regeneration Failure Counter is not reset, therefore P1435 remains CRNT and cannot be erased, and therefore MIL remains ON. Highlights: Consult-III software 8.16 was updated to solve above issue and ESM procedure was revised and updated accordingly. Please see the attachment for more details. Availability on Nissan-WORD: For J10 ESM: the updated procedure will be available in English, French, German, Spanish and Italian early May T31 ESM will be updated as well in the coming weeks.

2 < BASIC INSPECTION > INSPECTION AND ADJUSTMENT 1. Make sure that accelerator pedal is fully released. 2. Turn ignition switch ON and wait at least 15 seconds. Make sure that throttle valve moves during above 15 seconds by confirming the operating sound. 3. Turn ignition switch OFF and wait at least 3 minutes. 4. Turn ignition switch ON. A ECR >> END SERVICE REGENERATION SERVICE REGENERATION : Description INFOID: C Service Regeneration is performed with CONSULT-III to reduce particulate matter in DPF. Service Regeneration should be performed in the following cases. ECM enters fail-safe mode because the amount of particulate matter in DPF reaches the specified level. NOTE: When ECM enters fail-safe mode because the amount of particulate matter in DPF reaches the specified level, check whether or not DTC is stored in ECM. If the DTC is stored, perform the Diagnostic Procedure for the DTC. ECM is replaced. NOTE: Based on the signal from sensors, ECM measures the amount of particulate matter in DPF and stores the value in EEPROM (Electrically Erasable Programmable Read Only Memory). When ECM is replaced with a new one, there is a difference between the actual amount of particulate matter and the value stored in new ECM, because the value stored in new ECM is initialized. In the case above, ECM cannot perform regeneration control correctly. So, perform service regeneration to make the amount of particulate matter in DPF zero. Component Inspection for DPF is performed. CAUTION: Always replace engine oil and engine oil filter after service regeneration. Fuel mixes with engine oil during service regeneration. The mixture does not occur during the regeneration which is automatically performed under normal operation. SERVICE REGENERATION : Special Repair Requirement 1.PERFORM OK OR NG JUDGEMENT FOR SERVICE REGENERATION 1. Start engine and warm it up to normal operating temperature. 2. Select SERVC REGENERATION in WORK SUPPORT mode with CONSULT-III. 3. Touch Start. Which is displayed on CONSULT-III screen? Judged OK>>GO TO 3. Judged NG>>GO TO Turn ignition switch OFF. 2. Replace DPF. 3. Perform DPF Data Clear. Refer to ECR-18, "DPF DATA CLEAR : Special Repair Requirement".

3 < BASIC INSPECTION > INSPECTION AND ADJUSTMENT 1. Turn ignition switch OFF. 2. Replace engine oil and engine oil filter. Refer to XX-XX, "*****" and XX-XX, "*****". 3. Replace DPF. 4. Perform DPF Data Clear. Refer to ECR-18, "DPF DATA CLEAR : Special Repair Requirement". >> END 5.PERFORM RESET AFTER SERVICE REGENERATION 1. Touch RESET. 2. Check that COMPLETE is displayed on CONSULT-III screen. 3. Touch END. 4. Turn ignition switch OFF. 5. Replace engine oil and engine oil filter. Refer to XX-XX, "*****" and XX-XX, "*****". >> END DPF DATA CLEAR DPF DATA CLEAR : Description INFOID: Perform DPF DATA CLEAR in WORK SUPPORT mode with CONSULT-III when oxidation catalyst with DPF is replaced with a new one. Based on the signal from sensors, ECM estimates the amount of particulate matter in DPF and stores the value in EEPROM as DPF data. When oxidation catalyst with DPF is replaced with a new one, there is a difference between DPF data stored in ECM and the actual amount of particulate matter in DPF, because no particulate matter is trapped in new DPF. In this case, ECM cannot perform regeneration control correctly. So perform DPF DATA CLEAR in WORK SUPPORT mode with CONSULT-III to clear DPF data stored in ECM. CAUTION: Never perform DPF DATA CLEAR in WORK SUPPORT mode with CONSULT-III when oxidation catalyst with DPF is not replaced with a new one. DPF may be damaged because regeneration is not performed at appropriate timing. DPF DATA CLEAR : Special Repair Requirement 1.START 1. Turn ignition switch ON. 2. Select DPF DATA CLEAR in WORK SUPPORT mode with CONSULT-III. 3. Touch CLEAR and wait a few seconds. 4. Make sure that CMPLT is displayed on CONSULT-III screen. INFOID: >> END ECR-18

7 P1435 DPF REGENERATION Description P1435 DPF REGENERATION INFOID: PBIB3160E DPF (Diesel Particulate Filter) is placed after oxidation catalyst and traps PM (Particulate Matter) in exhaust gas. DPF is formed in a honeycomb shape made of ceramic. This structure facilitates to trap particulate matter. When the amount of particulate matter in the DPF reaches the specified level, the particulate matter needs to be reduced through burning to maintain the DPF function. This reduction of particulate matter is called regeneration and should be performed periodically.
