FNRP Pod Forward switch is shorted to power
Cause:
If the Forward signal voltage from FNRP pot is detected too high, the transmission controller will record this fault
code.
Possible failure modes:
1. The transmission control (FNRP) pot failure
2. Wiring harness problem from the transmission control (FNRP) pot to the transmission controller.
Solution:
The transmission control (FNRP) pod is directly wired to the transmission controller. The transmission controller
monitors the shuttle shifting and displays the shuttle position on the instrumentation cluster.
1. Troubleshooting by viewing the shuttle position display.
In some cases, problems can be detected by viewing the display while shifting the transmission control (FNRP)
lever.
Turn Key 'ON' and watch the shuttle position display.
If Forward icon stays lit up on display when not in Forward, either the Forward switch shorted internally or its wiring
shorted to power.
2. Troubleshooting by checking FNRP switch function.
Disconnect the cover panel under the steering column. Locate connector C051. Measure continuities on the
transmission control (FNRP) pot side.
Measure between Pin 6 (Forward) and Pin 8 (5 Vref), there should be about 500 - 600 Ohms when in Forward
position and about 2500 - 3000 Ohms when in other positions. If not, the Forward switch failed.
If the Forward switch failure is detected, replace the transmission control (FNRP) pot.
If no switch failure is detected, go to next step.
3. Check the wiring from connector C051 to the transmission controller.
If fault code 67 comes with fault code 69, there is a higher chance the failure is in the 5 V supply circuit.
Check the wiring between Pin 8 of connector C051 and pin 16 of connector C351 for shortage to power.
If fault code 67 comes without fault code 69, there is a higher chance the failure is in the Forward circuit. Check the
wiring between Pin 6 of connector C051 and pin 13 of connector C351 for shortage to power.
NOTE: Pay attention to bent pin, loose pin, wire damage, and any possible shortage between pins and wires
