#201 Inspection of relay (normally open, 5 pins) • Perform a continuity check and an operation check. If there is any abnormality, replace the relay. #318 Inspection of boost pressure sensor • Apply 5 volts DC to terminals 3 and 1. • Apply air pressure. Gradually increase it and, while doing so, measure the output… Read More »
• These inspections aid troubleshooting by enabling you to check whether electronic control unit signals are being correctly transmitted via the vehicle harness and connectors. The white-on-black numbers ( 01 , 02 and so on) correspond to the similarly printed reference number in section “3. Inspections Based on Diagnosis Codes”. 6.1 Electronic control unit connector… Read More »

3.1 Diagnosis code list • Diagnosis codes shown by the Multi-Use Tester and those indicated by flashing of the warning lamp are different. • The Multi-Use Tester is capable of showing more detailed diagnosis codes. • The control during fault recovers by servicing the faults. However, for some diagnosis codes, the warning lamp stays illuminated… Read More »
2. Diagnostic Precautions • Before measuring voltage, check the battery for charged condition and specific gravity. If system inspection is performed with the battery uncharged or reduced in specific gravity, accurate measurements cannot be achieved. • Before disconnecting battery cables, harnesses and connectors, set the starter switch to LOCK or OFF, then allow at least… Read More »
• Carry out system inspection in accordance with the flow chart given below.
• The engine electronic control unit stores the DPF-related information as historical records to facilitate the regeneration of the diesel particulate filter. • The initialization of the DPF-related information is performed to make the particulate matter (PM) deposit recognized by the engine electronic control unit coincide with the actual particulate matter (PM) deposit accumulated in… Read More »
• If the diesel particulate filter clogs early, or if a large amount of soot adheres inside the diesel particulate filter outlet body, check whether it is caused by the engine-related (engine, common rail system, exhaust gas recirculation system, etc.) fault or not as follows. 8.1 Preparation • Place the transmission in neutral. • Turn… Read More »
• These works should be performed at 12-month intervals as follows: 7.1 Preparation • Place the transmission in neutral. • Turn the steering wheel in neutral position and securely apply the parking brake. • Turn off lamps and accessory devices not to increase the engine speed. • Connect the Multi-Use Tester. (See Gr00.) • Check… Read More »
