Electrical Troubleshooting
TEST 6.7:
If the test at pin #4 on the 12-pin logic card connector failed, but the test at pin #5 at the
accelerator module was good (#6.5), then check the wire from pin #5 (module) to pin #4
(logic card).
If the test at pin #10 on the 12-pin logic card connector failed, but the test at pin #1 at
the accelerator module was good (#6.6), then check the wire from pin #1 (module) to pin
#10 (logic card).
Stop trouble shooting here and repair the problem. When the repair is completed, completely
retest the vehicle before lowering the drive wheels to the ground.
TEST 6.6:
Accelerator pedal depressed.
Test the voltage from pin #9 to pin #1.
If the voltage is between 4.8 and 5.1 volts, then
skip ahead to test #6.7.
If the voltage is not between 4.8 and 5.1 volts,
then the module has failed and must be replaced.
Stop trouble shooting here and repair the problem.
When the repair is completed, completely retest the
vehicle before lowering the drive wheels to the
ground.
TEST 6.5a:
Test the voltage from pin #5 to pin #8.
Accelerator pedal released.
If the voltage is low then skip ahead to test 6.5b.
If the voltage is high then then the module has
failed.
Stop trouble shooting here and repair the problem.
When the repair is completed, completely retest the
vehicle before lowering the drive wheels to the
ground.
TEST 6.5b:
Accelerator pedal depressed.
If the voltage equals battery volts, then skip ahead to test #6.6.
If the voltage does not equal battery volts, then the module has failed or the accelerator
pedal return spring on the module is broken.
Stop trouble shooting here and repair the problem. When the repair is completed, completely
retest the vehicle before lowering the drive wheels to the ground.
