ُ Go to "Component inspection" procedure.
ُ Check for open or short in harness. Repair as necessary and Go to "verification of vehicle repair"
procedure.
ُ If signal circuit in harness is OK, Substitute with a known-good PCM/TCM and check for proper

vehicle repair" procedure.
Component Inspection
1. IG "OFF" & Engine "OFF".
2. Disconnect ATM control Unit(CHG75-1 & CHG75-3) connector.
3. Measure resistance between signal and ground terminal of range switch connector (Component Side)

Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination,
deterioration, or damage. Repair or replace as necessary and then go to "Verification of Vehicle
Repair" procedure.
ُ Check for open or short in harness. Repair as necessary and Go to "verification of vehicle repair"
procedure.
ُ If signal circuit in harness is OK, Substitute with a known-good "TRANSMISSION RANGE SWITCH"
and check for proper operation. If the problem is corrected, replace "TRANSMISSION RANGE
SWITCH" as necessary and go to "verification of vehicle repair" procedure.
Verification of Vehicle Repair
1. Connect scan tool and select "Diagnostic Trouble Codes(DTCs)" mode.
