15. Bowden cable out of adjustment. This fault is generated if there is a fault with the inhibitor switch or the gear selector switches. The engine can only be started if the Immobilization ECU (EWS3) has a 12v supply from the Inhibitor switch. This supply is derived from passenger fusebox fuse 35. The Inhibitor switch is linked to the gear lever, via a Bowden cable, and is integral with the Gear Selector switches. The inhibitor switch is an integral part of the gear selector switch mechanism and should close when either Neutral or Park is selected. This then supplies 12v to the Immobilization ECU, (EWS3) which allows the engine to be started. This fault is also generated if the selector switch shows no selection, or more than one selection. The gear selection indicator lamps, by the gear lever, are driven directly by the selector switch. The switch is located on top of the transmission and is operated by the gear lever via a steel Bowden cable. Ensure that this cable is adjusted correctly.
16. Gear selector switch mechanism. This fault is generated if there is a fault with the inhibitor switch or the gear selector switches. The engine can only be started if the Immobilization ECU (EWS3) has a 12v supply from the Inhibitor switch. This supply is derived from passenger fusebox fuse 35. The Inhibitor switch is linked to the gear lever, via a Bowden cable, and is integral with the Gear Selector switches. The inhibitor switch is an integral part of the gear selector switch mechanism and should close when either Neutral or Park is selected. This then supplies 12v to the Immobilization ECU, (EWS3) which allows the engine to be started. This fault is also generated if the selector switch shows no selection, or more than one selection. The gear selection indicator lamps, by the gear lever, are driven directly by the selector switch. The switch is located on top of the transmission and is operated by the gear lever via a steel Bowden cable. Ensure that this cable is adjusted correctly.
17. Immobilizer EWS3 ECU. This fault is generated if there is a fault with the inhibitor switch or the gear selector switches. The engine can only be started if the Immobilization ECU (EWS3) has a 12v supply from the Inhibitor switch. This supply is derived from passenger fusebox fuse 35. The Inhibitor switch is linked to the gear lever, via a Bowden cable, and is integral with the Gear Selector switches. Ensure that C059/3 switches between 12v and ground when the gear selector is moved from Neutral or Park to Drive and that the connector is sound. If TestBook available, use the Basic Toolbox and diagnostics for the EWS3 ECU to investigate this fault in more detail.
18. JATCO ATCU ECU. This fault is generated if there is a fault with the inhibitor switch or the gear selector switches. The engine can only be started if the Immobilization ECU (EWS3) has a 12v supply from the Inhibitor switch. This supply is derived from passenger fusebox fuse 35. The Inhibitor switch is linked to the gear lever, via a Bowden cable, and is integral with the Gear Selector switches. Test the operation of the gear selector mechanism using Real Time Display and also check the gear position shown by the lamps by the gear lever. Fully investigate all other possibilities before replacing the JATCO ECU.

Both sides of the sensor should be free from contamination. Gas must be able to be absorbed by both sides of the sensor. Also check the sensor for any mechanical damage or cracks. INFORMATION If the oxygen sensor shows signs of damage or contamination that cannot be cleaned it should be renewed.

2. JATCO ATCU ECU.

1. Engine sensor or ECU problem. The JATCO ECU has reported a failure with one or more of:- Engine RPM. Engine temperature. Engine torque reduction. Engine throttle angle. Engine virtual throttle angle. These signals are derived from the Engine Management ECU. The fault may be due to the sensor or the Engine Management ECU. Read Engine Management ECU fault codes and check if any of the above faults are set. If TestBook available, use the Engine Management diagnostics to investigate this fault in more detail.
