2. Check indicator light on the combination meter assembly.
   1. Check that the height control indicator light (HI, N, LO) comes on of the combination meter assembly when positive battery voltage is applied to the terminals as shown in the chart below.

      Indicator Light	Battery Positive	Battery Negative
      HI	C8-16	C8-12
      N	C8-16	C8-11
      LO	C8-16	C8-10

      OK

      Height control indicator light (HI, N, LO) comes on.

NG → REPLACE COMBINATION METER ASSEMBLY 

OK: Go to next step

2. Measure the resistance according to the values in the table below.

   Standard resistance

   Tester Connection	Specified Condition
   S16-16 (HI) - C8-12	Below 1 Ω
   S16-17 (NR) - C8-11	Below 1 Ω
   S16-18 (LO) - C8-10	Below 1 Ω
   S16-16 (HI) - Body ground	10 kΩ or higher
   S16-17 (NR) - Body ground	10 kΩ or higher
   S16-18 (LO) - Body ground	10 kΩ or higher

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR
