PINPOINT TEST B: POWERTRAIN CONTROL MODULE (PCM) POWER RELAY

 Introduction
Normal Operation and Fault Conditions
Refer to the DTC Fault Trigger Conditions.
DTC Fault Trigger Conditions
DTC |
Description |
Fault Trigger Condition |
PCM P0685:00 |
ECM/PCM Power Relay Control Circuit/Open: No Sub Type Information |
Sets when the ISP-R circuit indicates the
ignition is in the OFF, ACC, or LOCK mode, and the amount of time the
PCM remains powered through the PCM power relay exceeds a predetermined
amount of time.
Ability to communicate with the PCM when the ignition is in the OFF,
ACC, or LOCK mode indicates a hard fault.
|
PCM P0686:00 |
ECM/PCM Power Relay Control Circuit Low: No Sub Type Information |
Sets when the ISP-R circuit indicates the
ignition is in the OFF, ACC, or LOCK mode, and the amount of time the
PCM remains powered through the PCM power relay exceeds a predetermined
amount of time.
Ability to communicate with the PCM when the ignition is in the OFF,
ACC, or LOCK mode indicates a hard fault.
|
PCM P0687:00 |
ECM/PCM Power Relay Control Circuit High: No Sub Type Information |
Sets when the ISP-R circuit indicates the
ignition is in the OFF, ACC, or LOCK mode, and the amount of time the
PCM remains powered through the PCM power relay exceeds a predetermined
amount of time.
Ability to communicate with the PCM when the ignition is in the OFF,
ACC, or LOCK mode indicates a hard fault.
|
PCM P0689:00 |
ECM/PCM Power Relay Sense Circuit Low: No Sub Type Information |
Sets when the ISP-R and the INJPWRM circuit
voltages do not correspond for a calibrated period of time.
The INJPWRM PID voltage reading should be 0 volts when the ignition is in the OFF, ACC or LOCK mode.
|
PCM P068A:00 |
ECM/PCM Power Relay De-Energized - Too Early: No Sub Type Information |
Sets when the non volatile random access
memory write did not complete successfully after the ignition key was
turned OFF, prior to PCM shutdown. This DTC also sets when the PCM power relay is de-energized too early.
|
PCM P0690:00 |
ECM/PCM Power Relay Sense Circuit High: No Sub Type Information |
Sets when the voltage from the ISP-R, the
INJPWRM or the VPWR circuit does not correspond for a calibrated period
of time.
|
PCM P06B8:00 |
Internal Control Module Non-Volatile Random Access Memory (NVRAM) Error: No Sub Type Information |
Sets when the PCM detects a concern with the ability of the PCM to
correctly store permanent Diagnostic Trouble Codes (DTCs).
Check for other
Diagnostic Trouble Codes (DTCs) and diagnose those first. Check for
aftermarket performance products. Check for an electrical or charging
system concern.
If an updated
calibration is available, update the calibration to the latest level. If
an updated calibration is not available, clear the Diagnostic Trouble
Codes (DTCs) and repeat the self-test. If this DTC is retrieved after a
PCM reprogramming, turn the ignition OFF and allow the PCM to complete a
normal power down sequence.
|
PCM P1793:00 |
Ignition Supply Malfunction >16, <7 volts: No Sub Type Information |
Sets when the PCM detects the ISP-R circuit voltage is less than 7 volts or greater than 16 volts.
|
PCM P2510:00 |
ECM / PCM Power Relay Sense Circuit Range/Performance: No Sub Type Information |
Sets when the PCM detects the voltage on the ISP-R and the INJPWRM circuits do not correspond for a calibrated period of time.
The INJPWRM PID voltage reading should be 0 volts when the ignition is in the OFF, ACC or LOCK mode.
|
PCM U300C:00 |
Ignition Input Off/On/Start: No Sub Type Information |
Sets when the PCM does not receive (or cannot detect) the ignition mode.

PINPOINT TEST Z: INTERMITTENT

 Introduction
Normal Operation and Fault Conditions
This pinpoint test is intended to diagnose and isolate intermittent concerns for all EEC
subsystems. Parameter identifiers (PIDs) corresponding to a circuit
can be used to aid in identifying the intermittent cause. Some circuits
do not have an associated PID or the PID may not be available and must be measured using a digital multimeter.
Refer to the DTC Fault Trigger Conditions.
DTC Fault Trigger Conditions
DTC |
Description |
Fault Trigger Condition |
PCM P0219:00 |
Engine Overspeed Condition: No Sub Type Information |
Sets when the PCM detects the vehicle is operated in a manner which
caused the engine speed to exceed a calibrated limit. The engine RPM is
continuously monitored and evaluated by the PCM . This DTC sets when the
RPM exceeds the calibrated limit set within the PCM . This DTC may be
accompanied by other Diagnostic Trouble Codes (DTCs).
For additional information on the engine RPM limiter, refer to
Powertrain Control Software.
If DTC P1285 or P1299 is present, disregard DTC P0219 at this time.
Diagnose DTC P1285 or P1299 first.
If there are no other symptoms, return the vehicle to the customer with
information about the DTC.

PCM P0297:00 |
Vehicle Overspeed Condition: No Sub Type Information |
Sets when the PCM
detects the vehicle is operated in a manner which caused the vehicle
speed to exceed a calibration limit. The vehicle speed is continuously
monitored and evaluated by the PCM . For additional information on the
vehicle speed limiter, refer to Powertrain Control Software.
If there are no other symptoms, return the vehicle to the customer with
information about the DTC .
