Toyota Hiace 2TR-FE 2.7L (2005–2016) Technical Manual – Complete Diagnostics ECM, Transmission, CAN Network and Synchronization Free PDFs

count on the four complete technical manuals in PDF format of the Toyota Hiace with 2TR-FE 2.7L gasoline engine It is an invaluable advantage for any automotive technician, student, or independent mechanic who wants to diagnose, repair, or understand in depth all the electronic and mechanical systems of this reliable unit.

The free download of these documents provides direct access to electrical schematics, CAN network diagrams, multimeter and oscilloscope testing, DTC coding, and the official step-by-step procedure for replacing the synchronization chain of the engine, one of the most delicate and critical tasks in the maintenance of this van.

These manuals not only cover the electronic injection and ignition system, but also document aspects such as the electronically controlled automatic transmission, the charging and starting system, the electric actuators, sensor reading and real-time response, as well as OBD-II system strategies for detecting faults, in addition to the vehicle's wiring and ground distribution.

ECM Terminals and Pins – 34, 40, and 48-pin Connectors

The engine control unit (ECU) in this unit uses three connectors for a total of 122 terminals. Some relevant pins include:

Sensors with specific tests included

Sensors with multimeter and oscilloscope

• CKP – Crankshaft Position
• CMP – Camshaft Position
• TPS – Electronic Throttle Position Sensor
• APP – Electronic pedal sensor
• MAF/IAT – Airflow and Temperature
• ECT – Coolant Temperature
• HO2S – Oxygen sensor (pre and post catalytic converter)

The manuals detail voltage curves, harness location, internal sensor resistance, and specific tests for each sensor with its operating range.

Documented electronic actuators and modules

• DIS coils – 5V digital signal (unusual in this design)
• Injectors – 14–16 Ohms resistance – activated from ECM
• VVT-i solenoid – Camshaft advance control
• Throttle Body Control System (ETCS)
• Canister purge valve (EVAP)
• Fuel pump relay

Automatic transmission system and electronic control

The ECM manages sensors and actuators related to the automatic transmission, such as:

• S1, S2, S3 switch solenoids
• OSS Output Speed ​​Sensor
• PRNDL lever position sensor
• Line pressure sensor

Also included are related DTC codes (P0700 to P0798), switching diagrams, and voltage curves.

Charging and starting system

• Alternator voltage – 13.5 to 14.8V with engine running
• Start relay – direct activation by switch
• Cable distribution between battery, fuses and starter motor

CAN-Bus diagnostics and module network

It includes the CAN network system diagram where the following are visualized:

• ECM
• ABS
• Instrument panel (Cluster)
• Airbag (if applicable)
• Body Unit (BCM)

Multimeter test points are included to verify CAN bus continuity, and the expected behavior of the CAN-H and CAN-L signals.

Synchronization Chain – Step-by-Step Guide

The complete procedure for chain replacement includes:

1. Exact position of piston No. 1 at top dead center (TDC)
2. Camshaft and crankshaft locking
3. Location of timing marks on links and gears
4. Tightening torque of each screw
5. Hydraulic tensioner assembly
6. Chain tension check
