Checking the Torque Limiting Function

Checking Torque Limiting, Steps 1 & 3:

1 Connect an ISAT scan tool, contact the SFI system and enter command code EE6O.


The status of the system is displayed on the ISAT:


^ With reverse gear selected -> PAE6O-ON. If not, go to point 2.

^ With the gear lever in neutral or the selector lever in the N position -> PAE60-OFF.

If not, go to point 6.


2 Check whether fuse FA9 is intact.

3 With the ignition switched off, connect a break-out box to the ECM wiring harness (ECM disconnected) and check (with the ignition switch turned to the Drive position) whether battery positive voltage is present on pin 13 of the ECM (reverse gear selected).


If voltage is present, the ECM may be faulty. Review "Before Replacing ECM."

Checking Torque Limiting, Steps 4 & 5:

4 If no voltage is present, check whether voltage is present up to:


^ Manual: Terminal 1 of the reversing light switch, and also terminal 2 when the switch is activated. If it is not, replace the switch or, alternatively, check the lead from terminal 1 of the switch to the fuse.

^ Automatic: Terminal 30 of the reversing light switch when the switch is activated.

If it is not, check the operation of the selector lever and the reversing light relay.


5 With the ignition switched off, use a break-out box to check the lead to pin 13 of the ECM for continuity/shorting to ground. Take remedial action if the lead is faulty.

Checking Torque Limiting, Steps 6 & 7:

6 Manual: Check that pin 2 of the brake light switch is not live when the switch is not activated. If it is, replace the brake light switch.


Automatic: Check that pin 30 of the reversing light relay is not live when the relay is not activated. If it is, check the operation of the selector lever and the reversing light relay.

7 With the ignition switched off, connect the break-out box to the ECM wiring harness (ECM disconnected).

Turn the ignition switch to the Drive position and check the lead to pin 14 of the ECM for shorting to battery positive voltage. Take remedial action if the cable is faulty.


If the cable is OK, the ECM may be faulty. Review "Before Replacing ECM."
