Galant L4-2.4L (4G69) (2004)
STEP 35. Check the powertrain control module for short circuit. Measure the resistance at powertrain control module connector B-19.
CAUTION: A digital multimeter should be used. For details refer to Service Precautions/Vehicle Damage Warnings.
1. Disconnect powertrain control module connector B-19, and measure the resistance at the component side of powertrain control module connector
B-19.
2. Measure the resistance between powertrain control module connector terminals 17 and 18.
OK: 120 ± 20 Ohms
Q: Does the resistance measure 120 ± 20 Ohms?
YES: If the resistance measures 120 ± 20 Ohms, diagnose CAN bus lines thoroughly. Refer to "Diagnostic Item 16".
NO: If the resistance does not measure 120 ± 20 Ohms, replace the powertrain control module.
Diagnostic Item 10
DIAGNOSTIC ITEM 10: Diagnose terminator resistors at both ends <Vehicles without ABS>
CAUTION: When servicing a CAN bus line, ground yourself by touching a metal object such as an unpainted water pipe. If you fail to do so, a
component connected to the CAN bus line may be damaged.
