The Toyota HiAce TRH200 series is the fifth generation of the Hi Ace brand and was built between 2005 and 2015.  It is a very popular choice with tradespeople and couriers. Even though these vehicle have been selected for their reliability and durability, our technicians have received calls from many owners experiencing a list of common issues with this vehicle, some of the most common problems being no injector pulse and no start condition.

Affected Vehicles: 

• Toyota HiAce TRH201 2.7L 2TRFE (2005-2015)
• Toyota HiAce TRH221 2.7L 2TRFE (2005-2015)
• Toyota HiAce TRH223 2.7L 2TRFE (2005-2015)

 Common Faults:

• No injector pulse
• No start
• Water damaged ECU
• Fault code B2799 - Immobiliser fault

 Diagnosis:

The Toyota Hi Ace runs a Denso designed Engine Control Module (ECM). This control module is mounted underneath the driver seat and due to the physical location of the ECM, it is often susceptible to water damage. For a vehicle with a no start issue, a full diagnostic scan of the vehicles system needs to be completed and all fault codes recorded.

If fault code B2799 is logged in the system, all immobiliser related wiring and connectors need to be checked for any issues. If an ECM is suspected of having water damage, a complete check of the vehicles wiring, and connectors should be done to make sure there is no contamination affecting the ECM's 5v reference values and grounds.

Solution:

If a check of the vehicles wiring and connectors is completed, and no issue is present the fault may lie with the ECM or in the case of B2799 the immobiliser itself.
