Diagnostic procedure

1. Checking combination switch

(a) Check combination switch.
Standard values:
Use a multimeter Standard
Switch position
to connect pins value
OFF 4 - 7 ≤ 2 Ω

04 INT 4 -7 12 - 16 ≤ 2 Ω

LO 7 - 18 ≤ 2 Ω
HI 13 - 18 ≤ 2 Ω

Are check results normal?
Yes > Go to step 2.
No > Replace combination switch.
2. Checking harness
(a) Use a multimeter to measure resistance of harness between pin 4 of three-in-one controller
and pin 16 of combination switch.
Resistance: ≤2Ω
Is check result normal?
Yes > Replace three-in-one controller.
No > Replace harness.
