The typical diagnosis for this fault is voltage low.
108.3.1 Low Voltage Check
Check as follows:
1. Disconnect the Accelerator Pedal (AP) connector.
2. Disconnect the #1 connector of the CPC.
3. Measure the resistance between pin 1 and pin 3 of the AP connector.
[a] If the resistance is less than 5 Ω, repair the short between wires 8 and 4 of the CPC
#1 connector. Refer to section 108.3.1.1.
[b] If the resistance is greater than 5 Ω, go to step 4.
4. Measure the resistance between pin 2 and 3 of the AP connector.
[a] If the resistance is less than 5 Ω, repair the short between wires 7 and 14 of the CPC
#! connector. Refer to section 108.3.1.1.
[b] If the resistance is greater than 5 Ω, go to step 5.
5. Measure the resistance between pin 1 of the AP connector and ground.
[a] If the resistance is less than 5 Ω, repair the short circuit between pin 1 of the AP
connector and ground. Refer to section 108.3.1.1.
[b] If the resistance is greater than 5 Ω, go to step 6.
6. Measure the resistance between pin 2 of the AP connector and ground.
[a] If the resistance is less than 5 Ω, repair the short circuit between pin 2 of the AP
connector and ground. Refer to section 108.3.1.1.
[b] If the resistance is greater than 5 Ω, replace the Accelerator Pedal. Refer to section
