ACCESSORY/SWITCH OUTPUT Diagnostic Code 14
Indicates a short circuit fault in the harness or the device being operated by
the Switch Output.
Troubleshoot the Switch/Timer Power diagnostic code based on:
Electrical switch circuit in the switch wiring.
Test procedure electrical, short circuit:
a) Remove the Switch Output harness at the G-II PCM.
b) Remote start the PROHEAT using the PROHEAT remote start switch
(PROHEAT P/N PK0091).
If the PROHEAT functions correctly, the fault is in the wiring from the
PROHEAT back to the switch. See OEM recommended service requirements.
If the PROHEAT does not function, the G-II PCM is faulty. Go to G-II PCM
replacement, page 4-38.
AUXILIARY OUTPUT Diagnostic Code 13
Indicates a short circuit fault in the harness or the device being operated by
the Auxiliary Output.
T
roubleshoot the Auxiliary Output diagnostic code based on:
G-II PCM – electrical
Test procedure – G-II PCM Output Signal:
a) Disconnect the Auxiliary Output harness at the G-II PCM.
b) Switch the PROHEAT on and operate for at least one complete cycle.
Observe the operation.
If the diagnostic code is not indicated the fault is in the harness or the
driven device. Go to OEM for service requirements.
If the diagnostic code is still indicated, the G-II PCM is faulty. Go to G-II
PCM replacement, page 4-38.

NOTICE
All plugs/harnesses must be rein-

Module (G-II PCM) before heater
goes back into service.
NOTICE
Depending on the G-II PCM part no.
the Auxiliary Mode output operates
in one of 4 following modes:
Normal: Auxiliary output is only on
when the heater is switched on.
Indicator: Auxiliary output behaves
exactly the same as the G-II PCM
indicator light.
Flame: Auxiliary output is only on
when the flame is on.
Preheat: Auxiliary output is only on
during Preheat mode.
Please refer to the M-Series Parts Book
at www.proheat.com for part numbers.
