4. Checking for exhaust brake indicator light signal and ground circuits open
(a) Ignition switch: OFF.
(b) Disconnect connector of combination
switch B029.

(c) Ignition switch: ON.
(d) Use a multimeter to measure voltage 4
between connector pins 10 and 1 and
voltage to ground of pin 10 of
combination switch B029 respectively.
Voltage: battery voltage

Are check results normal?
Yes > Replace combination switch assembly.
No > If battery voltage is not available in either case, go to step 7.
If battery voltage is not available between connector pins 1 and 10 of combination switch
B029, go to step 5.
5. Checking ground circuit from combination switch to ECM signal
(a) Ignition switch: OFF.
(b) Use a multimeter to measure resistance
to ground of connector pin 1 of
combination switch B029.
Resistance: ≤2Ω

Is check result normal?
Yes > Go to step 7.
No > Go to step 6.
