6. Key off. Use a multimeter to test for continuity between connector X020 pin J3-18 on CCM1 and chassis
ground. There should be low resistance ( <1 ohms) to ground.
A. If no continuity is found, or there is high resistance (>1 ohms) to ground, the CCM1 module is not
supplying a ground path for the sensor due to an internal failure. Replace the CCM1 module.
B. If continuity is found, the ground path for the sensor tests okay. Reconnect all connectors and retest for
continuity to ground at Step 2.
7. Disconnect connector X306, and use a multimeter to test for voltage on connector X306 pin 2. There should
not be any voltage present.
A. If no voltage is found, continue with Step 8.
B. If high (>4.7 volts) voltage is found, continue with Step 7.
8. Disconnect connector X032, and use a multimeter to test for voltage on the feeder (FE) harness end of
connector X032 pin 2. There should not be any voltage present.
A. If no voltage is found, there is a short to voltage in the header (HH) harness between connector X306
and connector X032 wire 739 yellow. Locate the short and repair.
B. If high (>4.7 volts) voltage is found, continue with Step 7.
9. Disconnect connector X007, and use a multimeter to test for voltage on the front frame (FF) harness end
of connector X007 pin 16. There should not be any voltage present.
A. If high (>4.7 volts) voltage is found, there is a short to high voltage in the front frame (FF) harness
between connector X007 pin 16 and connector X020 pin J3-22 wire 739 yellow. Locate the short
and repair.
B. If no voltage is found, there is a short to high voltage in the feeder (FE) harness between connector X032
pin 2 and connector X007 pin 16 wire 739 yellow. Locate the short and repair.
10. Disconnect connector X306, and use a multimeter to test for voltage on connector X306 pin 3. There should
be 5 volts present.
A. If 5 volts is found, continue with Step 11.
B. If high (>5 volts) voltage is found, continue with Step 11.
NOTE: This supply circuit is also used to supply power to the lateral tilt potentiometer R-02 and the shoe
leveling sensor in the shoe leveling actuator M03, so a short to 12 volts anywhere on the supply circuit will
activate this error code.
11. Disconnect connector X032, and use a multimeter to test for voltage on the feeder (FE) harness end of
connector X032 pin 5. There should be 5 volts present.
A. If 5 volts is found, there is a short to high voltage in the header (HH) harness between connector X306
and connector X032 wire 848 pink. Locate the short and repair.
B. If high (>5 volts) voltage is found, continue with Step 9.
12. Disconnect connector X007, and use a multimeter to test for voltage on connector X007 pin 22. There
should be 5 volts present.
A. If 5 volts is found, there is a short to high voltage in the feeder (FE) harness between connector X032
pin 5 and connector X007 pin 22 wire 848 pink or 757 pink. Locate the short and repair.
B. If high (>5 volts) voltage is found, continue with Step 10.
13. Disconnect connector X023, and use a multimeter to test for voltage on the front frame (FF) harness end of
connector X023 pin 17.
A. If 5 volts is found, there is a short to high voltage in the lower frame (LF) harness between connector
X088 pin A on the shoe leveling actuator M03 and connector X023 pin 17 wire 727 pink. Locate the
short and repair.
