ACP Trouble Codes
After SERVICE MODE is entered, all existing trouble codes will be displayed. Each trouble code consists of system abbreviation, a 3-digit code identifier, and letter "C" or "H".
System abbreviations are "E" for PCM codes, "I" for IPC codes, "A" for ACP codes, and "R" for SIR codes. See ACP TROUBLE CODES table. A "C" or "H" at end of code indicates whether code is current (fault still exists) or code is historical (failure occurred during one of last 50 ignition cycles).
| Code | Circuit Affected | Figure |
|---|---|---|
| A010 | Outside Temperature Sensor | Figure & Figure |
| A011 | A/C High-Side Temperature Sensor | Figure & Figure |
| A012 | A/C Low-Side Temperature Sensor | Figure & Figure |
| A013 | In-Car Temperature Sensor | Figure & Figure |
| A015 | Sunload Temperature Sensor | Figure & Figure |
| A037 | IPC-To-ACP Serial Data | Figure |
| A040 | Air-Mix Valve | Figure & Figure |
| A047 | Low Refrigerant Warning | Figure & Figure |
| A048 | Very Low Refrigerant Warning | Figure & Figure |
| A050 | High A/C High-Side Temperature | Figure |
If codes do not exist in memory for ACP, a NO A CODES message will be displayed. If IPC cannot communicate with ACP, a NO A DATA message will be displayed.
To repair affected circuit, see the ACP TROUBLE CODE CHARTS. After all trouble codes have been displayed, ACP system may be selected for testing. See SERVICE MODE OPERATION & EXITING DIAGNOSTICS.
