Ignition Sequence Troubleshoot

When diagnosing a remote start issue, one of the first steps is to troubleshoot the ignition sequence. This involves checking the voltage of the starter and ensuring that it is within an acceptable range. The voltage should be between 8V and 16V. If the starter voltage is outside of this range, it could indicate a problem with the starter itself or with other components in the ignition system. In addition to checking the voltage, it is also important to inspect all connections and wiring for corrosion or loose connections that could be causing an issue.

Battery Maintenance

Another important step when diagnosing a remote start issue is to check the batterys charge level and condition. A low charge level can prevent a remote start from engaging, so its important to check that the battery has enough charge before attempting any repairs or diagnostics. If necessary, use a multimeter to test the batterys voltage and ensure that it is between 12V and 15V. Its also important to check for corrosion on battery terminals, as this can prevent a good connection from being established between the battery and other components in the system.

Parts Replacement

If all other steps have been completed without success, then it may be necessary to replace some parts in order to get the remote start working again. The most common parts that need replacing are sensors, starters, and remote keyless entry systems (RKE). All of these components should be checked for wear and tear or damage before attempting any repairs or replacements. Also, if any parts have been replaced recently then they should be inspected again for any signs of damage or wear and tear that may have occurred during installation or use.

Electrical Connections Checkup

In addition to checking for worn out parts or damage, its also important to check all electrical connections for corrosion or loose connections that could be preventing a good connection from being established between components in the system. This includes inspecting all wiring in order to make sure that no wires are frayed or broken which could cause an issue with power delivery throughout the system. Its also important to ensure that all connectors are properly connected as well in order to ensure proper power delivery throughout different components in the system.

Fuse Box Testing & Replacement

The fuse box should also be tested during diagnosis of a remote start issue as fuses can blow due to overloading of electrical current which will cause an interruption of power supply throughout different components in the system. Checking main fuses for blown fuses as well as replacing any blown fuse parts are both important steps when trying diagnose why a remote start isn’t working properly on your 2012 Jeep Grand Cherokee.
