2007 laredo 4.7 litre...

2007 laredo 4.7 litre, dash lights say check guages, service suspension, engine light on, abs light on, no high beams and signal lights and hazards work intermittently

Mechanic's Assistant: Does the light stay on, or does it blink?

Stays on and also tach works intermittently, checked all fluid levels and battery is good

Mechanic's Assistant: What is the model of your '07 Jeep?

Laredo, same as Grand Cherokee

Mechanic's Assistant: Are you fixing your Grand Cherokee yourself? What have you tried so far?

Checked all fluids, checked battery voltage, scanned for codes but there are no DTC's

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

Radio quit working also

ok, did what you suggested and looks like it all reset but after running and driving for approx 10 minutes, the probles all returned.
Customer reply replied 24 days ago
problems all returned

ok , I believe the BCM body control module or IP(Instrument panel ) module like I mentioned before is our issue,in some cases we can reflash them with new updated software in some we replace them , do not waist time ,take to dealer there scanner will have the software and / or the scanner needed here to confirm and check for faults in pending and history files in these modules , i have changed several for same issue ,bcm is most common but ip also ,so we need to scan with capable scanner

the fact it reset is ,for sure one of these modules is cutting ,what we call can bus line between modules and all goes haywire , both of these modules bcm or ip will need a scanner to be replaced , they are not plug and play parts ,will need programed to car
