[B] Inspecting each device visually and physically
[C] Testing with a Circuit Tester
1. Causes when a break in wiring
[Test Conditions]
1. Key switch : OFF
2. AI console connector disconnected.
3. There is a break somewhere in the wiring.
Pull on the harness and make sure the connector/harness does
not come off. (pull with a max of 3 kgf (30 N, 7 lbf) of force) If it
comes off, plug the connector back in securely, turn the accelerator
dial to the right (hi-speed) and the left (lo-speed) and check the
voltage of the accelerator sensor again in the tester mode.
2. Causes when a short
[Test Conditions]
1. Key switch : OFF
2. The wiring of the AI console connector is pinched against or
touching the body.
If the insulation is damaged, repair it properly, turn the
accelerator dial to the right (hi-speed) and the left (lo-speed)
and check the voltage of the accelerator sensor again in the
tester mode.
