C1417 and C1241 Diagnostic Codes for 2012 Toyota Camry - Help Identifying Root Cause

Model: 2012 Camry Fault Code: C1241 Posted: 2020-11-27 23:51

I'm seeing two diagnostic trouble codes: C1417 and C1241 on my 2012 Toyota Camry. The battery was replaced in September, and the alternator has been recently replaced as well—previously it caused issues. I've checked the code book, but I'm looking for deeper mechanical insight from experienced technicians. What do these codes specifically indicate? Could they be related to voltage supply problems in the skid control ECU or elsewhere in the electrical system?

The C1417 and C1241 codes are typically associated with a voltage supply issue reported by the skid control ECU. It's essential to verify that the correct voltage is being supplied to the system using a multimeter. Refer to ALLDATA.com for detailed wiring diagrams and test procedures to ensure accurate diagnosis.

I've completed testing using the ALLDATA resources and narrowed down the problem to ABS harness pin 28, which shows no voltage when the key is in the 'on' position. The recommended fix is either a secure connection or replacement of the harness. However, I can't find any online guides on how to perform this repair. Is this a common issue? Does it require advanced tools or is it something a DIYer could handle?

If there's no voltage at pin 28, follow the circuit path to locate the fuse. Measure voltage across both sides of the fuse. If voltage is present at the fuse input but not reaching pin 28, this indicates an open circuit somewhere in between. If there's no voltage at the fuse input, trace the circuit backward to find the next test point—this method helps isolate whether the issue lies in wiring or a component failure.
