/**
 * Specializes in retrieving pending/intermittent Diagnostic Trouble Codes
 *
 * The PendingDTCRetriever class uses OBD Service Mode 07 to retrieve pending DTCs
 * from the vehicle's diagnostic system. These are codes for issues that have been
 * detected but haven't yet triggered the Malfunction Indicator Light (MIL).
 *
 * Key features:
 * - Retrieves pending/intermittent fault codes
 * - Uses OBD service mode 07 (0x07)
 * - Helps identify developing problems before they become active DTCs
 * - Works across all OBD-II compliant vehicles that support Mode 07
 * - Provides early diagnostic indications
 *
 * Pending DTCs are especially valuable for:
 * - Preventative maintenance
 * - Detecting intermittent issues
 * - Verifying repairs before clearing active DTCs
 * - Monitoring borderline component performance
 *
 * @example
 * ```typescript
 * // Create a retriever instance
 * const pendingRetriever = new PendingDTCRetriever(sendCommand);
 *
 * // Retrieve and parse pending DTCs
 * const dtcResponse = await pendingRetriever.retrieveRawDTCs();
 *
 * if (dtcResponse) {
 *   if (dtcResponse.troubleCodes && dtcResponse.troubleCodes.length > 0) {
 *     console.log(`Found ${dtcResponse.troubleCodes.length} pending DTCs:`);
 *     dtcResponse.troubleCodes.forEach(dtc => {
 *       console.log(`- ${dtc}`); // e.g., "P0456", "P0442"
 *     });
 *   } else {
 *     console.log("No pending DTCs found.");
 *   }
 * } else {
 *   console.error("Failed to retrieve pending DTCs");
 * }
 * ```
