What is the yellow wire on a Jeep Grand Cherokee?
The yellow wire with a bold black stripe around it is the airbag actuator wire. It is very obvious and not a problem when doing electrical work. Do not probe this wire. If a yellow wire with a big bold black stripe is probed it will likely set off the air bag and do bodily harm. Enough said! Check the battery for 12.5 volts.
Why does my Jeep Grand Cherokee have no power?
If there is no power, the problem is between the battery and relay. If there is power at the relay, have a helper hold the key in the start position. There should now be power to a second terminal. If there is no power, the problem is in the ignition switch or with the security system.
What does p0622 mean on a PCM?
A stored code P0622 means that the powertrain control module (PCM) has detected a malfunction with the generator field coil control circuit. The F simply reiterates the field coil control circuit is at fault. The field coil is probably most recognizable from its windings which are visible through the vent holes on most alternators.
Why does my p0622 generator keep resetting?
If voltage is discovered at the generator field coil control terminal, suspect a defective alternator/generator. If the alternator is charging, and the P0622 continues to reset, use the DVOM to test controller power supply fuses and relays.

When do you get a diagnostic trouble code?
Diagnostic Trouble Codes (DTC) are the codes generated and stored by the Powertrain Control Module (PCM) when the Onboard Diagnostic (OBD) system indicates a malfunction. Simply put, when your car system diagnoses that something went wrong, it will send a code indicating the specific fault.
What are the different types of trouble codes?
O2 sensor performance codes and O2 heater circuit codes are two types of oxygen sensor trouble codes. Circuit that warms up the oxygen sensor when your engine is first started, will be detected as fault by Oxygen Sensor, and it will set a heater codes. This is needed to decrease cold start emissions.
Can a check engine light show an OBD2 code?
When the system identifies an issue, it turns on the check engine light and provides real-time data in addition to a standardized series of Diagnostic Trouble Codes (or DTCs). With a code reader or scanner, you can access one or more OBD2 codes that indicate the issues.
What do you need to know about diagnostic trouble codes?
If your vehicle has this system, you need an OBD-II diagnostic scanner to communicate with its OBD system. The diagnostic trouble code is the code your OBD generates to tell you something is wrong.
Powertrain ( P -codes) category covers functions that include engine, transmission and associated drivetrain accessories. Network & Vehicle Integration ( U -codes) category covers functions that are shared among computers and systems on the vehicle. The first letter of the code will mark the system related to the trouble code.
What does the first letter of a trouble code mean?
Network & Vehicle Integration ( U -codes) category covers functions that are shared among computers and systems on the vehicle. The first letter of the code will mark the system related to the trouble code. The first digit in the code will tell you if the code is a generic or manufacturer specific code.
