E0695-04-HSW Lateral Tilt CCW Shorted to Low Source
(G.30.A.05.80 - G.30.B.53)
E0695-04 - HSW Lateral Tilt CCW Shorted to Low Source
Cause:
The Right Hand Module (RHM) has detected that the Handle Switch (HSW) Lateral Tilt CCW circuit voltage is <0.25
volts .
Possible failure modes:
1. The HSW Lateral Tilt CCW circuit is shorted to ground.
2. RHM internal failure.
3. Multi Function Handle (MFH) failure.
Solution:
1. Verify the fault is present. Enter the Infoview monitor - "Diagnose info" screen, "MFH" sub-menu. Select "HSW
Lateral Tilt CCW" and observe the voltage.
The normal operating range for the HSW Lateral Tilt CCW circuit is 0.25 - 5.5 volts .
A. If the voltage reading is <0.25 volts , continue with Step 2.
B. If the voltage reading is within the proper limits, the fault may be intermittent. Continue troubleshooting at
Step 3.
2. Verify the MFH is good. Turn off the ignition switch. Disconnect the Right Console Harness connector X028 .
Using an ohmmeter, measure the continuity between the positive (+) and negative (-) pins of the Right Console
Harness connector X028 according to the table below. Operate the respective switch while observing the ohm-
meter. When a switch is activated the meter should read between 1.5M - 1.7M ohms , and open when idle.
Check for shorted wiring to other pins as you test each circuit. Refer to the schematic as needed.

A. If all of the switches and wires test good, then the MFH is good. Reload the system software to see if
the fault code clears. If the fault is still present after reloading the software, replace the RHM. Continue
troubleshooting at Step 3.
